摘　　要：由于网络的快速发展,人们每天被大量的信息包围。如何从中找出有价值的信息成为急需解决的问题。而现在大多数搜索引擎采用的是关键词匹配的方式,无法从语义的层面上理解用户的需求,导致查不准和查不全的情况,最终不能满足用户的需求。提出了基于本体的语义查询系统模型,通过本体来组织知识,让计算机能读懂查询条件,同时用wordnet来辅助查询,从而提高信息的查准率和查全率。还提出借助wordnet实现本体自我完善的方法,并增加了关键词快速查找表来加快查询的速度。With the rapid development of web, people is always surrounded by lots of information. How to search a way to find the valuable information is a question to be dealt with immediately. At present, most searching engines use the method of key word matching to find the information. So the computer can not understand people＇s request based on semantic meaning. At last, the collected information is not full and precise, and people will not satisfy with the results. This paper designs a semantic searching system model based on ontology, which organizes information with ontology to make the computer know the request well and improves the precision and the completeness of information searched by users through the help of wordnet. At the same time, this paper puts forward a method to amend ontology by itself with wordnet. It also designs a table of key words finding to raise the speed of searching.
