摘　　要：采用传统基于关键字的全文搜索技术对政务信息进行检索,检索质量比较低。将本体技术与传统检索技术相结合,有利于用户的查询语义充分表达,进而提高检索质量。提出了具体实现方案,以及结合相关领域主题词表来设计政务本体、用本体概念的高频组合词汇提高辅助查询能力的方法。最后通过实例验证了理论的正确性。When traditional full-text searching technologies based on keywords are applied on government information, low quality results will be return. It is helpful to express searcher＇s meaning more completely by combining traditional full-text searching technology with ontology technology. Quality of information retrieval will be improved. A detailed solution is proposed. Later method of designing government ontology utilizing domain oriented thesaurus is discussed. How to use combined words with high frequency to assist searching is also discussed. At last a case verifies that it is right.
