This project is to develop enabling techniques for a large-scalemetasearch engine that aims at covering a much larger portion of theWeb and at the same time retrieving more up-to-date and more usefuldocuments than existing search engines and metasearch engines. Ametasearch engine is a system that supports unified access to multipleexisting search engines. It is estimated that there are hundreds ofthousands of search engines on the Web (including deep Web). Theproposed metasearch engine (WebScales) will attempt to connect toas many of these search engines as possible. The focus of the researchis on advancing highly scalable distributed information retrievaltechnology and the research issues to be investigated in this project include (1) how to discover these search engines automatically, (2) how to incorporate them into the proposed metasearch engine automatically, (3) how to identify potentially useful search engines to use for any given user query submitted to the metasearch engine, and (4) how to achieve high retrieval effectiveness.

该项目旨在为大规模搜索引擎开发使能技术，其目标是覆盖更大的网络部分，同时检索比现有搜索引擎和元搜索引擎更新、更有用的文档。元搜索引擎是一个支持对多个现有搜索引擎进行统一访问的系统。据估计，网络上有数十万个搜索引擎(包括深层网络)。拟议中的元搜索引擎(WebScales)将尝试连接尽可能多的这些搜索引擎。研究的重点是推进高可伸缩性的分布式信息检索技术，本项目要研究的问题包括(1)如何自动发现这些搜索引擎，(2)如何将它们自动整合到所提出的元搜索引擎中，(3)如何识别潜在有用的搜索引擎来用于提交给元搜索引擎的任何给定用户查询，以及(4)如何获得高检索效率。
