The ZIP archives in this directory contain source and pre-built language models. LA-Strings now knows how to identify 1371 languages and 4466 language/encoding pairs. Using optional trigram models from the An Crubadan web crawler project, an additional 120+ languages in UTF-8 can potentially be identified. Alternatively, a subset of 103 of the most-spoken languages can be used for greater speed. v1.24 2014-08-19: Improved n-gram weighting for language identification yields ~3% relative reduction in classification errors in preliminary testing. Improved byte-based subsampling in 'subsample' results in much more accurate size of result. Eliminated subsample.C dependencies on FramepaC to allow standalone distribution. Added option to MkLangID to perform frequency smoothing using a logarithmic mapping rather than P^y mapping; specify a negative smoothing value for -S to activate. Boosted model size for a small number of highly-confusible language sets to 15000 n-grams for better discrimination. Added --yali flag to eval.sh and counts.sh to support use of Majlis's Yet Another Language Identifier as language identification program in evaluations. Fixed some compiler warnings for GCC 4.3.2 and 4.8. Replaced numerous Bibles with known-redistributable copies. [[Added 178 languages; updated dozens more.]] [languages.db: total languages=1371+3, total models=4652+5, lang/code pairs=4466+5, total encodings=38] v1.23 2013-08-28: Added missing initializations to scan_strings so that bulk_extractor plugin extracts the same strings as the standalone version. Fixed multi-threading crash. Added setlocale("en_US.UTF-8") for systems on which setlocale("UTF-8") fails. Added --batch flag to eval.sh to run all identifications in a single invocation of the identification program, to avoid startup overhead (particularly for LangDetect and langid.py). Added util/score.C to perform bulk scoring on batch-mode identification output. Fixed eval.sh line-counting with --utf16be and --utf16le. Added pseudo-model for HTML markup. [languages.db: total languages=1193+3, total models=4004+5, lang/code pairs=3860+5, total encodings=38] v1.22 2013-07-30: Fleshed out bulk_extractor interface in scan_strings.C. Requires bulk_extractor v1.4.0 (tested with beta3). Added support for running langid.py (https://github.com/saffsd/langid.py) from eval.sh, and --minlen/--maxlen options for characterizing error rates at varying string lengths. Corrected problem with line counting in eval.sh when using --utf16be and --utf16le. Fixed bug in mklangid when building UTF16 models without using -2b/-2l/-8b/-8l. MkLangID was not correctly filtering ngrams for ASCII-16BE and UTF-16BE, because the deciding byte of the second character is the fourth byte of the ngram, and the filtering took place at the trigram-counting stage. Added make targets for language databases omitting UTF16 models. Modified build process to eliminate warnings for "top100" databases. Added several missing UTF16 models. Added romanized Hindi language models. Updated Marshallese training data to full Bible. Replaced Sumo-Mayangna (sum_NI) by Mayangna (yan_NI), following ISO 639-3 update. [[69 additional languages.]] [languages.db: total languages=1188+2, total models=3980+4, lang/code pairs=3843+4, total encodings=38]
