| 摘 要： | 人们借助搜索引擎在网络资源中查找所需信息,但搜索引擎本身并不理解要检索内容的真正含义,只是严格的按照关键词进行匹配.语义Web的目标是实现网络资源的机器理解,成为近年来一个新的研究热点.将Agent思想应用到语义Web中,提出了语义Web环境下的信息检索模型,介绍了模型中每个组成部分的功能.然后以图书信息检索为应用背景,将提出的信息检索模型进行了应用.结果表明,信息检索的查准率和查全率都有了较好的改善.

| Abstract: | Search engine is often employed to retrieve information needed.Regretfully,search engine only strictly does the match work according to the keywords,because it does not comprehend the real meaning of the information.Semantic web technology,due to its efforts to make the web resource understood by computers,is becoming a new research hotspot in recent years.With agent technology,an information retrieval model is put forward and specific functions of each component are explained.To further attest its feasibility,the information retrieval model is adopted in books information retrieval.The results show that the model improve the efficiency of infor-mation retrieval. |
