Annotator Generator

Annotator Generator is an examples-driven generator of fast text annotators. “Annotate” in this context means to add pronunciation or other information to each word, and/or to split text into words in a language that does not use spaces.

• You supply a corpus of pre-annotated texts for Annotator Generator to work out the rules and exceptions
• Annotator Generator creates code (in C, C#, Java, Go, Javascript, Dart, or Python with 2 and 3 compatibility) that hard-codes the rules for fast processing
• The resulting program should be able to annotate any text that contains words or phrases similar to those found in the examples
• It can output the annotations alone or it can combine them with the original text using HTML Ruby markup or simple braces
• If anything is unclear (didn’t happen in the examples, or there’s not enough context to figure out which example should be applied) then the program will leave it unannotated so you can pass it to a backup annotation program if you have one.
• If you have no backup annotator then try setting the -y option, which makes Annotator Generator try harder to find context-independent rules with context-dependent exceptions, so as to annotate as much text as possible. 
• Generated annotators can act as filters for Web Adjuster; options are also provided for generating Android apps, browser extensions, and clipboard annotators for Windows and Windows Mobile, or you could format the annotations on a Unix terminal

Legal considerations

Annotator code will contain individual words and some phrases from the original corpus (and these can be read even by people who do *not* have the unannotated version); with regards to copyright law, I expect the annotator code will count as an “index” to the collection, the copyright of which exists separately to that of the original collection, but laws do vary by country and I am not a solicitor so please act judiciously. 

Legally obtaining that original annotated corpus is up to you. If you are in the UK the government says non-commercial text mining is allowed (terms of use prohibiting *non-commercial* mining are unenforceable), provided you:

1. respect network stability (i.e. wait a long time between each download),

2. connect directly to the publisher (this law bypasses the *publisher’s* terms of use, not those of third-party search engines like Google),

3. use the result *only* for mining, not for republishing the original text (so you can’t publish your unprocessed crawl dumps either),

4. and still respect any prohibitions against sharing whatever mining tools you made for the site (as this law is only about text mining, not about the sharing of tools).

Laws outside the UK are different (and I’m not a lawyer) so check carefully. But if the website’s terms don’t actually prohibit writing an *unpublished* scraper for non-commercial mining purposes, perhaps you won’t need a legal exception—but you should still respect their bandwidth and do it slowly, both for moral reasons (it’s the right thing to do) and pragmatic ones (you won’t want their sysadmins and service providers taking action against you). 

Download and Usage

Download annogen.py; you will need Python (compatible with both Python 2.7 and Python 3+) and you will need a command prompt. 

annogen.py

Version 3.248

Usage: annogen.py [options]

Options:

• -h, --help show this help message and exit
• --infile=INFILE Filename of a text file (or a compressed .gz, .bz2 or .xz file or URL) to read the input examples from. If this is not specified, standard input is used.
• --incode=INCODE Character encoding of the input file (default utf-8)
• --mstart=MARKUPSTART The string that starts a piece of text with annotation markup in the input examples; default <ruby><rb>
• --mmid=MARKUPMID The string that occurs in the middle of a piece of markup in the input examples, with the word on its left and the added markup on its right (or the other way around if mreverse is set); default </rb><rt>
• --mend=MARKUPEND The string that ends a piece of annotation markup in the input examples; default </rt></ruby>
• -r, --mreverse Specifies that the annotation markup is reversed, so the text before mmid is the annotation and the text after it is the base text
• --no-mreverse Cancels any earlier --mreverse option in Makefile variables etc
• --reference-sep=REFERENCE_SEP Reference separator code used in the example input. If you want to keep example source references for each rule, you can label the input with ‘references’ (chapter and section numbers or whatever), and use this option to specify what keyword or other markup the input will use between each ‘reference’. The name of the next reference will be whatever text immediately follows this string. Note that the reference separator, and the reference name that follows it, should not be part of the text itself and should therefore not be part of any annotation markup. If this option is not set then references will not be tracked.
• --ref-name-end=REF_NAME_END Sets what the input uses to END a reference name. The default is a single space, so that the first space after the reference-sep string will end the reference name.
• --ref-pri=REF_PRI Name of a reference to be considered “high priority” for Yarowsky-like seed collocations (if these are in use). Normally the Yarowsky-like logic tries to identify a “default” annotation based on what is most common in the examples, with the exceptions indicated by collocations. If however a word is found in a high priority reference then the first annotation found in that reference will be considered the ideal “default” even if it’s in a minority in the examples; everything else will be considered as an exception.
• -s, --spaces Set this if you are working with a language that uses whitespace in its non-markedup version (not fully tested). The default is to assume that there will not be any whitespace in the language, which is correct for Chinese and Japanese.
• --no-spaces Cancels any earlier --spaces option in Makefile variables etc
• -c, --capitalisation Don’t try to normalise capitalisation in the input. Normally, to simplify the rules, the analyser will try to remove start-of-sentence capitals in annotations, so that the only remaining words with capital letters are the ones that are always capitalised such as names. (That’s not perfect: some words might always be capitalised just because they never occur mid-sentence in the examples.) If this option is used, the analyser will instead try to “learn” how to predict the capitalisation of all words (including start of sentence words) from their contexts.
• --no-capitalisation Cancels any earlier --capitalisation option in Makefile variables etc
• -w, --annot-whitespace Don’t try to normalise the use of whitespace and hyphenation in the example annotations. Normally the analyser will try to do this, to reduce the risk of missing possible rules due to minor typographical variations.
• --no-annot-whitespace Cancels any earlier --annot-whitespace option in Makefile variables etc
• --keep-whitespace=KEEP_WHITESPACE Comma-separated list of words (without annotation markup) for which whitespace and hyphenation should always be kept even without the --annot-whitespace option. Use when you know the variation is legitimate. This option expects words to be encoded using the system locale (UTF-8 if it cannot be detected).
• --normalised-file=NORMALISED_FILE Filename of an optional text file (or compressed .gz, .bz2 or .xz file) to write a copy of the normalised input for diagnostic purposes. If this is set to the same as --infile then it will be assumed the input file has already been normalised (use with care).
• --normalise-only Exit after normalising the input
• --no-normalise-only Cancels any earlier --normalise-only option in Makefile variables etc
• --post-normalise=POST_NORMALISE Filename of an optional Python module defining a dictionary called ‘table’ mapping integers to integers for arbitrary single-character normalisation on the Unicode BMP. This is meant for reducing the size of generated Android apps, and is applied in post-processing (does not affect rules generation itself). For example this can be used to merge the recognition of Full, Simplified and Variant forms of the same Chinese character in cases where this can be done without ambiguity, if it is acceptable for the generated annotator to recognise mixed-script words should they occur.
• --glossfile=GLOSSFILE Filename of an optional text file (or compressed .gz, .bz2 or .xz file or URL) to read auxiliary “gloss” information. Each line of this should be of the form: word (tab) annotation (tab) gloss. Extra tabs in the gloss will be converted to newlines (useful if you want to quote multiple dictionaries). When the compiled annotator generates ruby markup, it will add the gloss string as a popup title whenever that word is used with that annotation (before any reannotator option is applied). The annotation field may be left blank to indicate that the gloss will appear for all other annotations of that word. The entries in glossfile do not affect the annotation process itself, so it’s not necessary to completely debug glossfile’s word segmentation etc.
• -C, --gloss-closure If any Chinese, Japanese or Korean word is missing from glossfile, search its closure of variant characters also. This option requires the cjklib package.
• --no-gloss-closure Cancels any earlier --gloss-closure option in Makefile variables etc
• --glossmiss=GLOSSMISS Name of an optional file to which to write information about words recognised by the annotator that are missing in glossfile (along with frequency counts and references, if available)
• --glossmiss-hide=GLOSSMISS_HIDE Comma-separated list of references to hide from the glossmiss file (does not affect the glossmiss-omit option)
• --glossmiss-match=GLOSSMISS_MATCH If supplied, any references not matching this regular expression will be hidden from the glossmiss file (does not affect the glossmiss-omit option)
• -M, --glossmiss-omit Omit rules containing any word not mentioned in glossfile. Might be useful if you want to train on a text that uses proprietary terms and don’t want to accidentally ‘leak’ those terms (assuming they’re not accidentally included in glossfile also). Words may also be listed in glossfile with an empty gloss field to indicate that no gloss is available but rules using this word needn’t be omitted.
• --no-glossmiss-omit Cancels any earlier --glossmiss-omit option in Makefile variables etc
• --words-omit=WORDS_OMIT File (or compressed .gz, .bz2 or .xz file or URL) containing words (one per line, without markup) to omit from the annotator. Use this to make an annotator smaller if for example if you’re working from a rules file that contains long lists of place names you don’t need this particular annotator to recognise but you still want to keep them as rules for other annotators, but be careful because any word on such a list gets omitted even if it also has other meanings (some place names are also normal words).
• --manualrules=MANUALRULES Filename of an optional text file (or compressed .gz, .bz2 or .xz file or URL) to read extra, manually-written rules. Each line of this should be a marked-up phrase (in the input format) which is to be unconditionally added as a rule. Use this sparingly, because these rules are not taken into account when generating the others and they will be applied regardless of context (although a manual rule might fail to activate if the annotator is part-way through processing a different rule); try checking messages from --diagnose-manual.
• --rulesFile=RULESFILE Filename of an optional auxiliary binary file to hold the accumulated rules. Adding .gz, .bz2 or .xz for compression is acceptable. If this is set then the rules will be written to it (in binary format) as well as to the output. Additionally, if the file already exists then rules will be read from it and incrementally updated. This might be useful if you have made some small additions to the examples and would like these to be incorporated without a complete re-run. It might not work as well as a re-run but it should be faster. If using a rulesFile then you must keep the same input (you may make small additions etc, but it won’t work properly if you delete many examples or change the format between runs) and you must keep the same ybytes-related options if any.
• -n, --no-input Don’t process new input, just use the rules that were previously stored in rulesFile. This can be used to increase speed if the only changes made are to the output options. You should still specify the input formatting options (which should not change), and any glossfile or manualrules options (which may change). For the glossmiss and summary options to work correctly, unchanged input should be provided.
• --no-no-input Cancels any earlier --no-input option in Makefile variables etc
• --c-filename=C_FILENAME Where to write the C, C#, Python, Javascript, Go or Dart program. Defaults to standard output, or annotator.c in the system temporary directory if standard output seems to be the terminal (the program might be large, especially if Yarowsky-like indicators are not used, so it’s best not to use a server home directory where you might have limited quota).
• --c-compiler=C_COMPILER The C compiler to run if generating C and standard output is not connected to a pipe. The default is to use the “cc” command which usually redirects to your “normal” compiler. You can add options (remembering to enclose this whole parameter in quotes if it contains spaces), but if the C program is large then adding optimisation options may make the compile take a long time. If standard output is connected to a pipe, then this option is ignored because the C code will simply be written to the pipe. You can also set this option to an empty string to skip compilation. Default: cc -o annotator
• --max-or-length=MAX_OR_LENGTH The maximum number of items allowed in an OR-expression in non table-driven code (used when ybytes is in effect). When an OR-expression becomes larger than this limit, it will be made into a function. 0 means unlimited, which works for tcc and gcc; many other compilers have limits. Default: 100
• --nested-if Allow C/C#/Java/Go if() blocks (but not switch() constructs) to be nested to unlimited depth. This probably increases the workload of the compiler’s optimiser when reducing size, but may help when optimising for speed.
• --no-nested-if Cancels any earlier --nested-if option in Makefile variables etc
• --nested-switch=NESTED_SWITCH Allow C/C#/Java/Go switch() constructs to be nested to about this depth. Default 0 tries to avoid nesting, as it slows down most C compilers for small savings in executable size. Setting 1 nests 1 level deeper which can occasionally help get around memory problems with Java compilers. -1 means nest to unlimited depth, which is not recommended. Setting this to anything other than 0 implies --nested-if also.
• --outcode=OUTCODE Character encoding to use in the generated parser and rules summary (default utf-8, must be ASCII-compatible i.e. not utf-16)
• -S, --summary-only Don’t generate a parser, just write the rules summary to standard output
• --no-summary-only Cancels any earlier --summary-only option in Makefile variables etc
• -N, --no-summary Don’t add a large rules-summary comment at the end of the parser code
• --no-no-summary Cancels any earlier --no-summary option in Makefile variables etc
• -O SUMMARY_OMIT, --summary-omit=SUMMARY_OMIT Filename of a text file (or a compressed .gz, .bz2 or .xz file or URL) specifying what should be omitted from the rules summary. Each line should be a word or phrase, a tab, and its annotation (without the mstart/mmid/mend markup). If any rule in the summary exactly matches any of the lines in this text file, then that rule will be omitted from the summary (but still included in the parser). Use for example to take out of the summary any entries that correspond to things you already have in your dictionary, so you can see what’s new.
• --maxrefs=MAXREFS The maximum number of example references to record in each summary line, if references are being recorded (0 means unlimited). Default is 3.
• -R, --norefs Don’t write references in the rules summary (or the glossmiss file). Use this if you need to specify reference-sep and ref-name-end for the ref-pri option but you don’t actually want references in the summary (which speeds up summary generation slightly). This option is automatically turned on if --no-input is specified.
• --no-norefs Cancels any earlier --norefs option in Makefile variables etc
• -E, --newlines-reset Have the annotator reset its state on every newline byte. By default newlines do not affect state such as whether a space is required before the next word, so that if the annotator is used with Web Adjuster’s htmlText option (which defaults to using newline separators) the spacing should be handled sensibly when there is HTML markup in mid-sentence.
• --no-newlines-reset Cancels any earlier --newlines-reset option in Makefile variables etc
• -z, --compress Compress annotation strings in the C code. This compression is designed for fast on-the-fly decoding, so it saves only a limited amount of space (typically 10-20%) but might help if RAM is short; see also --data-driven.
• --no-compress Cancels any earlier --compress option in Makefile variables etc
• -D, --data-driven Generate a program that works by interpreting embedded data tables for comparisons, instead of writing these as code. This can take some load off the compiler (so try it if you get errors like clang’s “section too large”), as well as compiling faster and reducing the resulting binary’s RAM size (by 35-40% is typical), at the expense of a small reduction in execution speed. Javascript, Python and Dart output is always data-driven anyway.
• --no-data-driven Cancels any earlier --data-driven option in Makefile variables etc
• -F, --fast-assemble Skip opcode compaction when using data-driven (slightly speeds up compilation, at the expense of larger code size)
• --no-fast-assemble Cancels any earlier --fast-assemble option in Makefile variables etc
• -Z, --zlib Enable --data-driven and compress the embedded data table using zlib (or pyzopfli if available), and include code to call zlib to decompress it on load. Useful if the runtime machine has the zlib library and you need to save disk space but not RAM (the decompressed table is stored separately in RAM, unlike --compress which, although giving less compression, at least works ‘in place’). Once --zlib is in use, specifying --compress too will typically give an additional disk space saving of less than 1% (and a runtime RAM saving that’s greater but more than offset by zlib’s extraction RAM). If generating a Javascript annotator with zlib, the decompression code is inlined so there’s no runtime zlib dependency, but startup can be ~50% slower so this option is not recommended in situations where the annotator is frequently reloaded from source (unless you’re running on Node.js in which case loading is faster due to the use of Node’s “Buffer” class).
• --no-zlib Cancels any earlier --zlib option in Makefile variables etc
• -l, --library Instead of generating C code that reads and writes standard input/output, generate a C library suitable for loading into Python via ctypes. This can be used for example to preload a filter into Web Adjuster to cut process-startup delays.
• --no-library Cancels any earlier --library option in Makefile variables etc
• -W, --windows-clipboard Include C code to read the clipboard on Windows or Windows Mobile and to write an annotated HTML file and launch a browser, instead of using the default cross-platform command-line C wrapper. See the start of the generated C file for instructions on how to compile for Windows or Windows Mobile.
• --no-windows-clipboard Cancels any earlier --windows-clipboard option in Makefile variables etc
• -#, --c-sharp Instead of generating C code, generate C# (not quite as efficient as the C code but close; might be useful for adding an annotator to a C# project; see comments at the start for usage)
• --no-c-sharp Cancels any earlier --c-sharp option in Makefile variables etc
• --java=JAVA Instead of generating C code, generate Java, and place the *.java files in the directory specified by this option. See --android for example use. The last part of the directory should be made up of the package name; a double slash (//) should separate the rest of the path from the package name, e.g. --java=/path/to/wherever//org/example/package and the main class will be called Annotator.
• --android=ANDROID URL for an Android app to browse. If this is set, code is generated for an Android app which starts a browser with that URL as the start page, and annotates the text on every page it loads. Use file:///android_asset/index.html for local HTML files in the assets directory; a clipboard viewer is placed in clipboard.html, and the app will also be able to handle shared text. If certain environment variables are set, this option can also compile and sign the app using Android SDK command-line tools (SDK 24 or higher is required on the build machine, but the resulting app will be compatible with all versions of Android back to 1.x); if the necessary environment variables are not set, this option will just write the files and print a message on stderr explaining what needs to be set for automated command-line building.
• --android-template=ANDROID_TEMPLATE File to use as a template for Android start HTML. This option implies --android=file:///android_asset/index.html and generates that index.html from the file specified (or from a built-in default if the special filename ‘blank’ is used). The template file may include URL_BOX_GOES_HERE to show a URL entry box and related items (offline-clipboard link etc) in the page, in which case you can optionally define a Javascript function ‘annotUrlTrans’ to pre-convert some URLs from shortcuts etc and ‘desktopURL’ if you have a page about how to get a desktop version (e.g. via browser extension); also enables better zoom controls on Android 4+, a mode selector if you use --annotation-names, a selection scope control on recent-enough WebKit, and a visible version stamp (which, if the device is in ‘developer mode’, you may double-tap on to show missing glosses). VERSION_GOES_HERE may also be included if you want to put it somewhere other than at the bottom of the page. If you do include URL_BOX_GOES_HERE you’ll have an annotating Web browser app that allows the user to navigate to arbitrary URLs: as of 2020, this is acceptable on Google Play and Huawei AppGallery, but not Amazon AppStore as they don’t want ‘competition’ to their Silk browser.
• -L, --pleco-hanping In the Android app, make popup definitions link to Pleco or Hanping if installed
• --no-pleco-hanping Cancels any earlier --pleco-hanping option in Makefile variables etc
• --bookmarks=BOOKMARKS Android bookmarks: comma-separated list of package names that share our bookmarks. If this is not specified, the browser will not be given a bookmarks function. If it is set to the same value as the package specified in --java, bookmarks are kept in just this Android app. If it is set to a comma-separated list of packages that have also been generated by annogen (presumably with different annotation types), and if each one has the same android:sharedUserId attribute in AndroidManifest.xml’s ‘manifest’ tag (you’ll need to add this manually), and if the same certificate is used to sign all of them, then bookmarks can be shared across the set of browser apps. But beware the following two issues: (1) adding an android:sharedUserId attribute to an app that has already been released without one causes some devices to refuse the update with a ‘cannot install’ message (details via adb logcat; affected users would need to uninstall and reinstall instead of update, and some of them may not notice the instruction to do so); (2) this has not been tested with Google’s new “App Bundle” arrangement, and may be broken if the Bundle results in APKs being signed by a different key. In June 2019 Play Console started issuing warnings if you release an APK instead of a Bundle, even though the “size savings” they mention are under 1% for annogen-generated apps.
• -e, --epub When generating an Android browser, make it also respond to requests to open EPUB files. This results in an app that requests the ‘read external storage’ permission on Android versions below 6, so if you have already released a version without EPUB support then devices running Android 5.x or below will not auto-update past this change until the user notices the update notification and approves the extra permission.
• --no-epub Cancels any earlier --epub option in Makefile variables etc
• --android-print When generating an Android browser, include code to provide a Print option (usually print to PDF) and a simple highlight-selection option. The Print option will require Android 4.4, but the app should still run without it on earlier versions of Android.
• --no-android-print Cancels any earlier --android-print option in Makefile variables etc
• --android-audio=ANDROID_AUDIO When generating an Android browser, include an option to convert the selection to audio using this URL as a prefix, e.g. https://example.org/speak.cgi?text= (use for languages not likely to be supported by the device itself). Optionally follow the URL with a space (quote carefully) and a maximum number of words to read in each user request. Setting a limit is recommended, or somebody somewhere will likely try ‘Select All’ on a whole book or something and create load problems. You should set a limit server-side too of course.
• --android-urls=ANDROID_URLS Whitespace-separated list of URL prefixes to offer to be a browser for, when a matching URL is opened by another application in Android 1 through 11. If any path (but not scheme or domain) contains .* then it is treated as a pattern instead of a prefix, but Android cannot filter on query strings (i.e. text after question-mark). On Android 12+ this option won’t work at all unless the specified domain(s) approved your app.
• --extra-js=EXTRA_JS Extra Javascript to inject into sites to fix things in the Android browser app. The snippet will be run before each scan for new text to annotate. You may also specify a file to read: --extra-js=@file.js or --extra-js=@file1.js,file2.js (do not use // comments in these files, only /* ... */ because newlines will be replaced), and you can create variants of the files by adding search-replace strings: --extra-js=@file1.js:search:replace,file2.js
• --tts-js Make Android 5+ multilingual Text-To-Speech functions available to extra-js scripts (see TTSInfo code for details)
• --no-tts-js Cancels any earlier --tts-js option in Makefile variables etc
• --existing-ruby-js-fixes=EXISTING_RUBY_JS_FIXES Extra Javascript to run in the Android browser app whenever existing RUBY elements are encountered; the DOM node above these elements will be in the variable n, which your code can manipulate or replace to fix known problems with sites’ existing ruby (such as common two-syllable words being split when they shouldn’t be). Use with caution. You may also specify a file to read: --existing-ruby-js-fixes=@file.js
• --delete-existing-ruby Set the Android app or browser extension to completely remove existing ruby elements. Use this when you expect to replace a site’s own annotation with a completely different type of annotation. If you also supply --existing-ruby-js-fixes and/or --existing-ruby-shortcut-yarowsky, then --delete-existing-ruby specifies that only the first --sharp-multi option should have existing ruby preserved.
• --existing-ruby-shortcut-yarowsky Set the Android browser app to ‘shortcut’ Yarowsky-like collocation decisions when adding glosses to existing ruby over 2 or more characters, so that words normally requiring context to be found are more likely to be found without context (this may be needed because adding glosses to existing ruby is done without regard to context)
• --extra-css=EXTRA_CSS Extra CSS to inject into sites to fix things in the Android browser app. You may also specify a file to read --extra-css=@file.css
• --app-name=APP_NAME User-visible name of the Android app
• --compile-only Assume the code has already been generated by a previous run, and just run the compiler
• --no-compile-only Cancels any earlier --compile-only option in Makefile variables etc
• -j, --javascript Instead of generating C code, generate JavaScript. This might be useful if you want to run an annotator on a device that has a JS interpreter but doesn’t let you run your own binaries. The JS will be table-driven to make it load faster (and --no-summary will also be set). See comments at the start for usage.
• --no-javascript Cancels any earlier --javascript option in Makefile variables etc
• -6, --js-6bit When generating a Javascript annotator, use a 6-bit format for many addresses to reduce escape codes in the data string by making more of it ASCII. Not relevant if using zlib.
• --no-js-6bit Cancels any earlier --js-6bit option in Makefile variables etc
• -8, --js-octal When generating a Javascript annotator, use octal instead of hexadecimal codes in the data string when doing so would save space. This does not comply with ECMAScript 5 and may give errors in its strict mode. Not relevant if using zlib.
• --no-js-octal Cancels any earlier --js-octal option in Makefile variables etc
• -9, --ignore-ie8 When generating a Javascript annotator, do not make it backward-compatible with Microsoft Internet Explorer 8 and below. This may save a few bytes. Not relevant if using zlib.
• --no-ignore-ie8 Cancels any earlier --ignore-ie8 option in Makefile variables etc
• -u, --js-utf8 When generating a Javascript annotator, assume the script can use UTF-8 encoding directly and not via escape sequences. In some browsers this might work only on UTF-8 websites, and/or if your annotation can be expressed without the use of Unicode combining characters.
• --no-js-utf8 Cancels any earlier --js-utf8 option in Makefile variables etc
• --browser-extension=BROWSER_EXTENSION Name of a Chrome or Firefox browser extension to generate. The extension will be placed in a directory of the same name (without spaces), which may optionally already exist and contain icons like 32.png and 48.png to be used.
• --dart Instead of generating C code, generate Dart. This might be useful if you want to run an annotator in a Flutter application.
• --no-dart Cancels any earlier --dart option in Makefile variables etc
• --dart-datafile=DART_DATAFILE When generating Dart code, put annotator data into a separate file and open it using this pathname. Not compatible with Dart’s “Web app” option, but might save space in a Flutter app (especially along with --zlib)
• -Y, --python Instead of generating C code, generate a Python module. Similar to the Javascript option, this is for when you can’t run your own binaries, and it is table-driven for fast loading.
• --no-python Cancels any earlier --python option in Makefile variables etc
• --golang=GOLANG [Deprecated] Package name for a Go library to generate instead of C code. See comments in the generated file for how to run this on a first-generation AppEngine runtime (Go 1.11 or below). Deprecated because second-generation AppEngine runtimes work differently and the “flexible” option can run C code; this option will probably be removed if they shut down the non-flexible free-tier runtimes.
• --reannotator=REANNOTATOR Shell command through which to pipe each word of the original text to obtain new annotation for that word. This might be useful as a quick way of generating a new annotator (e.g. for a different topolect) while keeping the information about word separation and/or glosses from the previous annotator, but it is limited to commands that don’t need to look beyond the boundaries of each word. If the command is prefixed by a # character, it will be given the word’s existing annotation instead of its original text, and if prefixed by ## it will be given text#annotation. The command should treat each line of its input independently, and both its input and its output should be in the encoding specified by --outcode.
• -A, --reannotate-caps When using --reannotator, make sure to capitalise any word it returns that began with a capital on input
• --no-reannotate-caps Cancels any earlier --reannotate-caps option in Makefile variables etc
• --sharp-multi Assume annotation (or reannotator output) contains multiple alternatives separated by # (e.g. pinyin#Yale) and include code to select one by number at runtime (starting from 0). This is to save on total space when shipping multiple annotators that share the same word grouping and gloss data, differing only in the transcription of each word.
• --no-sharp-multi Cancels any earlier --sharp-multi option in Makefile variables etc
• --annotation-names=ANNOTATION_NAMES Comma-separated list of annotation types supplied to sharp-multi (e.g. Pinyin,Yale), if you want the Android app etc to be able to name them. You can also set just one annotation names here if you are not using sharp-multi.
• -o, --allow-overlaps Normally, the analyser avoids generating rules that could overlap with each other in a way that would leave the program not knowing which one to apply. If a short rule would cause overlaps, the analyser will prefer to generate a longer rule that uses more context, and if even the entire phrase cannot be made into a rule without causing overlaps then the analyser will give up on trying to cover that phrase. This option allows the analyser to generate rules that could overlap, as long as none of the overlaps would cause actual problems in the example phrases. Thus more of the examples can be covered, at the expense of a higher risk of ambiguity problems when applying the rules to other texts. See also the -y option.
• --no-allow-overlaps Cancels any earlier --allow-overlaps option in Makefile variables etc
• -P, --primitive Don’t bother with any overlap or conflict checks at all, just make a rule for each word. The resulting parser is not likely to be useful, but the summary might be.
• --no-primitive Cancels any earlier --primitive option in Makefile variables etc
• -y YBYTES, --ybytes=YBYTES Look for candidate Yarowsky seed-collocations within this number of bytes of the end of a word. If this is set then overlaps and rule conflicts will be allowed when seed collocations can be used to distinguish between them, and the analysis is likely to be faster. Markup examples that are completely separate (e.g. sentences from different sources) must have at least this number of (non-whitespace) bytes between them.
• --ybytes-max=YBYTES_MAX Extend the Yarowsky seed-collocation search to check over larger ranges up to this maximum. If this is set then several ranges will be checked in an attempt to determine the best one for each word, but see also ymax-threshold and ymax-limitwords.
• --ymax-threshold=YMAX_THRESHOLD Limits the length of word that receives the narrower-range Yarowsky search when ybytes-max is in use. For words longer than this, the search will go directly to ybytes-max. This is for languages where the likelihood of a word’s annotation being influenced by its immediate neighbours more than its distant collocations increases for shorter words, and less is to be gained by comparing different ranges when processing longer words. Setting this to 0 means no limit, i.e. the full range will be explored on all Yarowsky checks.
• --ymax-limitwords=YMAX_LIMITWORDS Comma-separated list of words (without annotation markup) for which the ybytes expansion loop should run at most two iterations. This may be useful to reduce compile times for very common ambiguous words that depend only on their immediate neighbours. Annogen may suggest words for this option if it finds they take inordinate time to process.
• --ybytes-step=YBYTES_STEP The increment value for the loop between ybytes and ybytes-max
• -k, --warn-yarowsky Warn when absolutely no distinguishing Yarowsky seed collocations can be found for a word in the examples
• --no-warn-yarowsky Cancels any earlier --warn-yarowsky option in Makefile variables etc
• -K, --yarowsky-all Accept Yarowsky seed collocations even from input characters that never occur in annotated words (this might include punctuation and example-separation markup)
• --no-yarowsky-all Cancels any earlier --yarowsky-all option in Makefile variables etc
• --yarowsky-multiword Check potential multiword rules for Yarowsky seed collocations also. Without this option (default), only single-word rules are checked.
• --no-yarowsky-multiword Cancels any earlier --yarowsky-multiword option in Makefile variables etc
• --yarowsky-thorough Recheck Yarowsky seed collocations when considering if any multiword rule would be needed to reproduce the examples. This could risk ‘overfitting’ the example set.
• --no-yarowsky-thorough Cancels any earlier --yarowsky-thorough option in Makefile variables etc
• --yarowsky-half-thorough Like --yarowsky-thorough but check only what collocations occur within the proposed new rule (not around it), less likely to overfit
• --no-yarowsky-half-thorough Cancels any earlier --yarowsky-half-thorough option in Makefile variables etc
• --yarowsky-debug=YAROWSKY_DEBUG Report the details of seed-collocation false positives if there are a large number of matches and at most this number of false positives (default 1). Occasionally these might be due to typos in the corpus, so it might be worth a check.
• --normalise-debug=NORMALISE_DEBUG When --capitalisation is not in effect. report words that are usually capitalised but that have at most this number of lower-case exceptions (default 1) for investigation of possible typos in the corpus
• -1, --single-words Do not consider any rule longer than 1 word, although it can still have Yarowsky seed collocations if -y is set. This speeds up the search, but at the expense of thoroughness. You might want to use this in conjuction with -y to make a parser quickly. It is like -P (primitive) but without removing the conflict checks.
• --no-single-words Cancels any earlier --single-words option in Makefile variables etc
• --max-words=MAX_WORDS Limits the number of words in a rule; rules longer than this are not considered. 0 means no limit. --single-words is equivalent to --max-words=1. If you need to limit the search time, and are using -y, it should suffice to use --single-words for a quick annotator or --max-words=5 for a more thorough one (or try 3 if --yarowsky-half-thorough is in use).
• --multiword-end-avoid=MULTIWORD_END_AVOID Comma-separated list of words (without annotation markup) that should be avoided at the end of a multiword rule (e.g. sandhi likely to depend on the following word)
• --checkpoint=CHECKPOINT Periodically save checkpoint files in the specified directory. These files can save time when starting again after a reboot (and it’s easier than setting up Condor etc). As well as a protection against random reboots, this can be used for scheduled reboots: if file called ExitASAP appears in the checkpoint directory, annogen will checkpoint, remove the ExitASAP file, and exit. After a run has completed, the checkpoint directory should be removed, unless you want to re-do the last part of the run for some reason.
• --checkpoint-period=CHECKPOINT_PERIOD Approximate number of seconds between checkpoints (default 1000). Setting this to 0 disables periodic checkpoints but still allows use of checkpoint directory for concurrency or ExitASAP processing.
• -d DIAGNOSE, --diagnose=DIAGNOSE Output some diagnostics for the specified word. Use this option to help answer “why doesn’t it have a rule for...?” issues. This option expects the word without markup and uses the system locale (UTF-8 if it cannot be detected).
• --diagnose-limit=DIAGNOSE_LIMIT Maximum number of phrases to print diagnostics for (0 means unlimited); can be useful when trying to diagnose a common word in rulesFile without re-evaluating all phrases that contain it. Default: 10
• -m, --diagnose-manual Check and diagnose potential failures of --manualrules
• --no-diagnose-manual Cancels any earlier --diagnose-manual option in Makefile variables etc
• -q, --diagnose-quick Ignore all phrases that do not contain the word specified by the --diagnose option, for getting a faster (but possibly less accurate) diagnostic. The generated annotator is not likely to be useful when this option is present. You may get quick diagnostics without these disadvantages by loading a --rulesFile instead.
• --no-diagnose-quick Cancels any earlier --diagnose-quick option in Makefile variables etc
• --priority-list=PRIORITY_LIST Instead of generating an annotator, use the input examples to generate a list of (non-annotated) words with priority numbers, a higher number meaning the word should have greater preferential treatment in ambiguities, and write it to this file (or compressed .gz, .bz2 or .xz file). If the file provided already exists, it will be updated, thus you can amend an existing usage-frequency list or similar (although the final numbers are priorities and might no longer match usage-frequency exactly). The purpose of this option is to help if you have an existing word-priority-based text segmenter and wish to update its data from the examples; this approach might not be as good as the Yarowsky-like one (especially when the same word has multiple readings to choose from), but when there are integration issues with existing code you might at least be able to improve its word-priority data.
• -t, --time-estimate Estimate time to completion. The code to do this is unreliable and is prone to underestimate. If you turn it on, its estimate is displayed at the end of the status line as days, hours or minutes.
• --no-time-estimate Cancels any earlier --time-estimate option in Makefile variables etc
• -0, --single-core Use only one CPU core even when others are available on Unix
• --no-single-core Cancels any earlier --single-core option in Makefile variables etc
• -p STATUS_PREFIX, --status-prefix=STATUS_PREFIX Label to add at the start of the status line, for use if you batch-run annogen in multiple configurations and want to know which one is currently running
