Open-source dependency parser, part-of-speech tagger, and text normalizer for Farsi (Persian).
(1) Dependency Parser: Downloadable as TurboParser model file from www.ark.cs.cmu.edu/TurboParser. Compatible with TurboParser v2.0.2. Please note this is not the current version of TurboParser; this dependency parser model is not tested with newer versions of TurboParser.
(2) Part-of-Speech Tagger: farsi_tagger.model file downloadable here. Please see www.ark.cs.cmu.edu/TurboParser for instructions on how to use this POS tagger. Compatible with TurboTagger v2.0.2. Please note this is not the current version of TurboTagger; this part-of-speech tagger model is not tested with newer version of TurboTagger.
(3) Farsi Text Normalizer: Downloadable as a python script.
Usage: python farsiNorm.py (-a for Arabic text) (-e for normalize ellipsis) infile > outfile
Please also download our Farsi Verb Tokenizer here: www.github.com/mehdi-manshadi/Farsi-Verb-Tokenizer
Pre-process your Farsi text using a sentence segmenter and tokenizer such as the Mojgan Seraji's SeTPer (http://stp.lingfil.uu.se/~mojgan/setper.html). Then, use our Farsi Verb Tokenizer (see above) and our Farsi Text Normalizer (see above) as two additional pre-processing steps. Finally, tag and parse your line-separated sentences using TurboTagger and TurboParser, with our POS tagger model file (see above) and dependency parser model file (see above). Use the TurboParser documentation (http://www.cs.cmu.edu/~afm/TurboParser/README) to learn how to tag and parse data.
