摘要
数字图书馆现有的检索引擎和检索技术由于无法提供上下文的语义信息,已经无法满足用户的检索需求。语义网技术可以很好的表达数字图书馆的内容,因此将语义网相关技术引入数字图书馆检索可以提高检索的精度。虽然数字图书馆的信息资源利用元数据表达并可以通过OAI-PMH进行访问,但是仍有很大部分需要语义网组件进行完善。在此基础上,提出了一个面向数字图书馆的通用模型的语义框架,这个框架可以满足用户高度个性化的信息需求。
Search engines and search techniques have fallen short of user expectations as they do not give context based retrieval.Deploying semantic web technologies would lead to efficient and more precise representation of digital library content and hence better retrieval.Though digital libraries often have metadata of information resources which can be accessed through OAI-PMH,much remains to be accomplished in making digital libraries semantic web compliant.This paper presented a semantic infrastructure for digital libraries,that will go a long way in providing them and web based information services with products highly customized to users needs.
