DepPattern
DepPattern toolkit (also in github) is a linguistic package providing a grammar compiler, PoS taggers, and dependency based parsers for several languages. It's provided with an user guide (pdf).
The compiler, named 'compi', was implemented in Ruby. It generates parsers in PERL from DepPattern grammars. To write formal grammars using the formalism ”DepPattern”, please, look up the tutorial (pdf).
In addition, DepPattern is provided with parsers for 5 languages: English, Spanish, Galician, French, and Portuguese. The parsers were implemented in PERL and are stored in the directory “parsers”.
Three demos are available: a basic demo allowing some sentences to be analyzed, a grammar-based demo where the user inserts his/her own grammar, and advanced demo to analyze text files.
Software download
Click here to download DepPattern (a more recent version available at github), a toolkit containing both multilingua natural language parsers implemented with Perl and a compiler implemented in ruby. Machine requirements are the following:
- A GNU Linux distribution
- Perl interpreter in /usr/bin
- Ruby interpreter in /usr/bin (how to install)
- (Optional) POS tagger Freeling
Click here to download the different grammars and source files we have written so far. In order the grammars to be compiled into the corresponding parsers, please follow the user guide.
