基于多语本体的语义查询扩展研究
Semantic Query Expansion Based on Multilingual Ontology
摘要
Abstract
Query expansion is an effective method to enhance information retrieval performance. Aiming at the requirements of acquiring multilingual information and solving the problems of semantic disambiguation of cross language information retrieval (CLIR), the article proposed a new semantic query expansion method based on multilingual ontology, and introduced its fundamentals, model and realization process, to turn character-matching into semantic matching for CLIR, implementing query expansion in CLIR, which may optimize system’s recal and precision.关键词
