| 摘 要： | 分析了信息检索和信息过滤的搜索过程，前者是在静态信息源中搜索用户短期的特定信息需求的过程；后者是在动态信息源中搜索用户长期的特定信息需求的过程。通过对信息需求与信息源关系图的分析，可以采用整合信息检索技术和信息过滤技术的方法，也可以在信息检索技术和信息过滤技术的基础上，研究新的信息搜索技术，来实现在动态信息源中搜索用户短期的特定信息需求。

| Abstract: | The paper analyzed the information seeking processes of information retrieval and information filtering. The former is an information seeking process that information is selected from the static information sources to satisfy users' specific short term information needs,and the latter is an information seeking process that information is selected from the dynamic information sources to satisfy users' specific long term information needs. In order to carry out an information seeking process that information is selected from the dynamic information sources to satisfy users' specific short term information needs, after analyzing relationship of diagram on information need and information sources, we can use method of integrating information retrieval technology with information filtering technology,and we can also use method of researching sophisticated technology on the basis of information retrieval technology and information filtering technology. |
