Abstract

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 cross-language hierarchies. The results showed a 15.1% improvement over the baseline non-hierarchy 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.
