Research on Bilingual Dependency Relationship Mapping for Chinese-English Lexicon Construction

Currently context-based approach is a popular approach for constructing bilingual lexicons from comparable bilingual corpora.Specifically,the dependency context model extracts context features from a sentence's dependency tree.This model improves the performance of the bilingual lexicon construction since dependency relationships can better capture the co-occurrence relationship between words.Following this line,this paper further proposes a dependency relationship mapping model,which constructs bilingual lexicon by mapping dependency context words,dependency relationship types and directions simultaneously.The experiments on the FBIS corpus show that,our approach significantly outperforms a state-of-the-art system in bilingual lexicon construction from both Chinese-English and English-Chinese.This justifies the effectiveness of our dependency relationship mapping model on bilingual lexicon construction.
