基于后向链接的查询路由研究

Study of Query Routing Based on Backward Links

尽管通用搜索引擎已经被广泛使用，但它们筛选用户查询结果中无关结果的功能一直不能任人满意，因此有些搜索需要使用专题搜索引擎。文章提出了一种基于中文专题搜索引擎的查询路由架构，该架构为用户的查询寻找合适的专题搜索引擎路由，并找出最佳搜索引擎。除了描述构架外，其中使用到的查询扩展和聚类算法文章也一并给出。

Though general-purpose search engines are widely used, their ability to filter irrelevant results in response to user queries are still not satisfying. Consequently, specialized topic-specific search engines are needed. This paper proposes an automatic query routing architecture, this architecture attempts to dynamically route each user query to the appropriate topic-specific search engines, and picks up the best search engine for the query. Besides describing the architecture , the query expansion and clustering algorithms it relies on are also included.
