Cross-lingual Dependency Parsing Based on Distributed Representations

##Cross-lingual Dependency Parsing Based on Distributed Representations Jiang Guo, [email protected]

This parser can be used both for monolingual and cross-lingual dependency parsing. The monolingual component has been optimized and integrated into LTP.

###Compile

Require: cmake (available in most Linux systems)

• ./configure
• make

###Resources

Alignment dictionaries:

• resources/align/PROJ (target->source)
• resources/align/CCA (source->target).

Note that the EN word embeddings in PROJ are used only for initialization, they get updated/finetuned while training.

###Running the executable

For robust projection: ./train-PROJ.sh

• set fix_word_embeddings=false (conf/nndep.cfg)

For CCA: ./train-CCA.sh

Learning parameters are defined in conf/nndep.cfg.
