中文摘要：

在分析已有检索工具和理论的基础上，提出基于构件的协同检索的桠架模型．对检索模型的信息收集、整理、分析、展示等功能进行模块设计，使用构件技术使检索模型具有较大的扩展性；利用协同技术实现用户指定的构件间的自动整合．通过定义一个架构让使用者能够根据自己的需求，设计相应的处理模块．通过对检索请求的理解和对数据内容的分析，利用合适的构件对用户的查询计划、意图、兴趣方向进行推理，内动进行信息搜集过滤，将用户感兴趣的、对用户有用的信息提交给用户．

英文摘要：

Based on the comprehensive, systematical and thorough analysis of existing tools and theoretical basis, a cooperative retrieval model based on components is proposed. The model consists of information gathering part, storing part ,reasoning part and searching part. Using component technology, the retrieval model has greater expansibility. Using collaborative technology the retrieval model can achieve user-specified automatic integration between components. This paper defines a framework which allows users to design the appropriate processing module according to their needs. Using appropriate component to deal with data, it will submit useful information to user.
