Notes on the current release

The current version is based on the frwikinews-20130110 articles dump [3]. It has 28000 news articles covering a period from January 2005 to now. After filtering of sentences with less than 5 tokens the version has 87461 sentences and 2535396 tokens. Texts are available under Creative Commons Attribution 2.5 (CC-BY 2.5) licence. Prior versions from September 2005 are in public domain. The text format have been cleaned up by using a Java Wikipedia API [4], then tokenized using a rule-/dictionary-based tokenizer [5], then POS tagged by the Stanford tagger [6]. Models were built on the human verified corpus [7]. In the associate paper, we show that automatically annotated data can be used to train a pos tagger with similar performance than the original one (no statistically significant difference) if the automatically annotated corpus is large enough.
