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).
Unzip the embeddings:
cd resources && unzip acl15-cl-wemb.zip && mv acl15-cl-wemb/cca cca && mv acl15-cl-wemb/projected projected && rm -r acl15-cl-wemb && cd ..
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: ./scripts/train-PROJ.sh
- set
fix_word_embeddings=false(conf/nndep.cfg)
For CCA: ./scripts/train-CCA.sh
Learning parameters are defined in conf/nndep.cfg.
