Retrieving Bilingual Verb–noun Collocations by Integrating Cross-Language Category Hierarchies

This paper presents a method of retrieving bilingual collocations of a verb and its objective noun from cross-lingual documents with similar contents. Relevant documents are obtained by integrating crosslanguage hierarchies. The results showed a 15.1 % improvement over the baseline nonhierarchy model, and a 6.0 % improvement over use of relevant documents retrieved from a single hierarchy. Moreover, we found that some of the retrieved collocations were domain-specific.
