Construction of Chinese-English Semantic Hierarchy for Information Retrieval

Abstract

This paper describes an approach to large-scale construction of a semantic hierarchy for Chinese verbs. Leveraging off of an existing Chinese conceptual database called HowNet and a Levin-based English verb classification, we use thematic-role information to create links between Chinese concepts and English classes. The resulting hierarchy is used for multilingual lexicons in an English-Chinese cross-language information retrieval application. We demonstrate a structured syntax interface that exploits this large-scale hierarchy and its linkages to WordNet for English-Chinese cross-language information retrieval.
