Result integration in a meta Web search engine

摘要

A meta Web search engine first sends a user's search requests to its referenced search engines. The results returned by these search engines are then integrated by one result-integrating algorithm and returned to the user. Query precision, completeness and response speed are directly affected by the choice of result integration algorithm. By analyzing common result-integrating algorithms, this paper recommends several unproved algorithms to improve the coherence of search results.
