【摘要】：用戶需要檢索的信息往往分散存儲在多個搜索引擎各自的數(shù)據(jù)庫里 .對普通用戶而言 ,訪問多個搜索引擎并從返回的結(jié)果中分辨出確實有用的網(wǎng)頁是一件費時費力的工作 .集成搜索引擎則可以提供給用戶一個同時訪問多個搜索引擎的集成環(huán)境 .集成搜索引擎能將其接收到的用戶查詢提交給底層的多個搜索引擎進行搜索 .作為一種搜索工具 ,集成搜索引擎具有如 WEB查詢覆蓋面比傳統(tǒng)引擎更大 ,引擎有更好的可擴展性等優(yōu)點 .討論了解決集成搜索引擎的數(shù)據(jù)庫選擇問題的多種技術(shù) .針對用戶提交的查詢要求 ,通過數(shù)據(jù)庫選擇可以選定最有可能返回有用信息的底層搜索引擎
[Abstract]:The information that users need to retrieve is often stored in the respective databases of multiple search engines. It is a time-consuming and laborious task for ordinary users to visit multiple search engines and identify useful web pages from the results returned. Integrated search engine can provide users with an integrated environment to access multiple search engines at the same time. An integrated search engine can submit the user queries it receives to multiple search engines at the bottom. As a search tool, integrated search engine has many advantages, such as WEB query coverage is greater than traditional engine, engine has better scalability and so on. This paper discusses a variety of techniques to solve the database selection problem of integrated search engine. For user-submitted query requirements, database selection allows you to select the underlying search engine that is most likely to return useful information
