目的探讨一种基于中医古籍文献数据库的语义检索系统的构建方法。方法以本体作为知识组织的方法,以protégé作为本体构建的工具,通过调用protégé OWL API接口,建立领域本体与传统数据库之间的访问机制。结果构建了一种基于领域本体的语义检索系统原型。结论该系统通过领域本体的语义扩展,提高了中医古籍文献数据库的查全率和查准率。
Objective To explore a method of constructing a semantic retrieval system based on the ancient Chinese medical literature database. Methods Using ontology as a method of knowledge organization and using protégé as a tool for ontology construction, an access mechanism between domain ontology and traditional database was established by calling Protégé OWL API. Results A prototype of semantic retrieval system based on domain ontology was constructed. Conclusion The system improves the recall rate and precision of ancient Chinese literature database by semantic extension of domain ontology.
