主题搜索引擎中爬虫搜索策略的研究
Research on search strategy of web spider in topic-oriented search engines
摘要
Abstract
In order to solve the low efficiency problem of traditional focused crawler, web spider always selects the most valuable links to visit, so how to focus the search around a given topic is a key problem. The traditional method always only computes the relevance of the links, but ignores the relevance among the unlabeled URL, now it proposes the algorithm based on link model which combines the seed URL with unlabeled URL to compute the relevance of the other URL, and it deduces the point that initial iterative is insensitivity of the results. Compared with the methods based on traditional algorithm, experimental result proves the performance of the new algorithm is more efficient than the traditional ones.关键词
