集成搜索引擎的文本数据库选择
发布时间：2019-04-17 14:12
【摘要】：用户需要检索的信息往往分散存储在多个搜索引擎各自的数据库里 .对普通用户而言 ,访问多个搜索引擎并从返回的结果中分辨出确实有用的网页是一件费时费力的工作 .集成搜索引擎则可以提供给用户一个同时访问多个搜索引擎的集成环境 .集成搜索引擎能将其接收到的用户查询提交给底层的多个搜索引擎进行搜索 .作为一种搜索工具 ,集成搜索引擎具有如 WEB查询覆盖面比传统引擎更大 ,引擎有更好的可扩展性等优点 .讨论了解决集成搜索引擎的数据库选择问题的多种技术 .针对用户提交的查询要求 ,通过数据库选择可以选定最有可能返回有用信息的底层搜索引擎
[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
