摘要
在分析已有相关研究的基础上设计一个基于会话管理的W eb即时信息检索代理JITIRA,该代理对用户提交给搜索引擎的查询或打开的新网页进行处理,并在此基础上即时构造新查询,并代替用户提交给搜索引擎。实验表明该方法有助于提高查准率。
On the basis of analyzing related works, JITIRA, a just-in-time information retrieval agent is designed. The agent processes the queries which submitted to search engines or the newly opened webpage by users. Then, the agent forms automatically a new query immediately, and submits it to search engines. The experiment demonstrates that the above method is helpful to improve the re- trieval precision of search engines.
