wordfreq/CHANGELOG.md

4.0 KiB
Raw Blame History

Version 1.7.0 (2017-08-25)

  • Tokenization will always keep Unicode graphemes together, including complex emoji introduced in Unicode 10
  • Update the Wikipedia source data to April 2017
  • Remove some non-words, such as the Unicode replacement character and the pilcrow sign, from frequency lists
  • Support Bengali and Macedonian, which passed the threshold of having enough source data to be included

Version 1.6.1 (2017-05-10)

  • Depend on langcodes 1.4, with a new language-matching system that does not depend on SQLite.

    This prevents silly conflicts where langcodes' SQLite connection was preventing langcodes from being used in threads.

Version 1.6.0 (2017-01-05)

  • Support Czech, Persian, Ukrainian, and Croatian/Bosnian/Serbian
  • Add large lists in Chinese, Finnish, Japanese, and Polish
  • Data is now collected and built using Exquisite Corpus (https://github.com/LuminosoInsight/exquisite-corpus)
  • Add word frequencies from OPUS OpenSubtitles 2016
  • Add word frequencies from the MOKK Hungarian Webcorpus
  • Expand Google Books Ngrams data to cover 8 languages
  • Expand language detection on Reddit to cover 13 languages with large enough Reddit communities
  • Drop the Common Crawl; we have enough good sources now that we don't have to deal with all that spam
  • Add automatic transliteration of Serbian text
  • Adjust tokenization of apostrophes next to vowel sounds: the French word "l'heure" is now tokenized similarly to "l'arc"
  • Multi-digit numbers of each length are smashed into the same word frequency, to remove meaningless differences and increase compatibility with word2vec. (Internally, their digits are replaced by zeroes.)
  • Another new frequency-merging strategy (drop the highest and lowest, average the rest)

Version 1.5.1 (2016-08-19)

  • Bug fix: Made it possible to load the Japanese or Korean dictionary when the other one is not available

Version 1.5.0 (2016-08-08)

  • Include word frequencies learned from the Common Crawl
  • Support Bulgarian, Catalan, Danish, Finnish, Hebrew, Hindi, Hungarian, Norwegian Bokmål, and Romanian
  • Improve Korean with MeCab tokenization
  • New frequency-merging strategy (weighted median)
  • Include Wikipedia as a Chinese source (mostly Traditional)
  • Include Reddit as a Spanish source
  • Remove Greek Twitter because its data is poorly language-detected
  • Add large lists in Arabic, Dutch, Italian
  • Remove marks from more languages
  • Deal with commas and cedillas in Turkish and Romanian
  • Fix tokenization of Southeast and South Asian scripts
  • Clean up Git history by removing unused large files

  • Add zipf_frequency function

Announcement blog post

Version 1.3 (2016-01-14)

  • Add Reddit comments as an English source

Version 1.2 (2015-10-29)

  • Add SUBTLEX data
  • Better support for Chinese, using Jieba for tokenization, and mapping Traditional Chinese characters to Simplified
  • Improve Greek
  • Add Polish, Swedish, and Turkish
  • Tokenizer can optionally preserve punctuation
  • Detect when sources stripped "'t" off of English words, and repair their frequencies

Announcement blog post

Version 1.1 (2015-08-25)

  • Use the 'regex' package to implement Unicode tokenization that's mostly consistent across languages
  • Use NFKC normalization in Japanese and Arabic

Version 1.0 (2015-07-28)

  • Create compact word frequency lists in English, Arabic, German, Spanish, French, Indonesian, Japanese, Malay, Dutch, Portuguese, and Russian
  • Marginal support for Greek, Korean, Chinese
  • Fresh start, dropping compatibility with wordfreq 0.x and its unreasonably large downloads
