P2P Web搜索中一种有效的查询路由策略
An Effective Query Routing Strategy over P2P Web Search
摘要
Abstract
Effective multi-keyword query routing is the key problem over P2P Web search. A novel query processing strategy based on benefit cost ratio was proposed A P2P overlay based on DHT has been built, and take into account of the correlation of keywords as well as the coverage and overlap among peers. Min-wise independent permutation was applied for overlap detection, so the redundant routing to the same result is avoided. The experimental results show that the method improves the search performance greatly.关键词
