中文摘要：

目前信息检索正在向着领域化、智能化方向发展。针对农业领域的分支领域茶虫害为研究对象,通过构建茶虫害领域本体,设计并实现了基于茶虫害本体的智能检索系统。该系统在特定主题的限定下进行信息的搜集和检索,能识别所搜索的网页与主题是否相关,而且能产生智能导航链接在主题最相关的范围内搜索,把信息检索从目前基于关键词层面提升到基于知识的层面,从而能够帮助用户更容易地找到感兴趣的信息,提高信息服务的质量和信息检索的准确率。

英文摘要：

At present information retrieval is developing to the direction of domain and intelligence.With the tea pest of agricultural sub-field as the research object and the construction of the tea pest domain ontology,an intelligent retrieval system is setup based on the ontology,which can collect and retrieve information with a limited subject,and can give the relationship between the collected website and the subject,and the link of intelligent navigation can be produced to retrieve information under the scope of the most relevant subject.It upgrades the information retrieval from the level of keywords-based to the level of knowledge-based.The system can help users to find the interesting information more easily,and enhance the quality of information services and the accuracy of information retrieval.
