摘要
本文针对信息技术这一特定领域,提出了一个通过元搜索引擎向特定用户群体—高校教师提供科研项目信息服务的系统,使其可以使用基于关键词的检索、目录式检索以及信息推送服务。该系统通过元搜索引擎提供统一的访问服务,同时利用用户检索行为信息动态反馈其兴趣主题并调整文档聚类结果,因此可有效提高项目信息检索的查准和查全率,更好地帮助用户快速检索到所需的科研项目信息。
Aimed at IT frontier area, this paper presented an information retrieval service system based on meta search engine technology for a specific user group which was consisted of universities or colleges＇ teachers. The system could offer users key retrieval, catalog searching and information pushing service by a unified access interface. It could dynamically catch the user＇s real interesting topics and feedback the clustering result set according to the user＇s operation log, and as a result, it could highly improve the accuracy and integrity of information retrieval for users to meet their real requirements for applying R＆D projects by using our custom search engine.
