为解决中药新药研发中的信息集成和检索问题，设计并实现了语义搜索系统TCMSearch。为实现分布式、异构数据库的语义集成和一致性访问，提出语义视图，来定义关系型数据库与领域本体之间的模式映射。该系统根据关系型数据库的语义视图，将用户提出的语义查询重写为结构查询语言（SQL）查询，再分派给各个关系型数据库，最终将查询结果进行语义封装。它还基于本体构建文本内容的语义索引，从而实现了基于概念的内容检索。这些本体驱动的方法，使该系统与关键词搜索系统相比，具有更高的查准率与查全率。该系统已成功部署，它基于一个大型中药领域本体，通过Web方式为中药领域专家提供智能搜索服务。

Objective: To facilitate the integration and retrieval of information in Traditional Chinese Medicine (TCM) pharmaceutics, a semantic search system named TCMSearch was designed and implemented. To enable the semantic integration and consistent access of distributed and heterogeneous databases, semantic views were proposed to define the mappings between relational databases and ontologies. Guided by semantic views, the system translated user-posed semantic queries into SQL queries against source databases, and generated the semantic encapsulation of SQL results. The system constructed semantic index for textual content, to enable concept-based content retrieval. By using these ontology-driven methods, the system achieved better performance in precision and recall than keyword-based search systems. After its deployment, the system provided intelligent search services to domain experts.
