| Abstract: | In the light of result returned currently by general-purpose search engines being excessive, and having no strong similarity with the topic, this paper covers a technique of dividing the web page to chunks to implement a focused crawler. With this method, Crawlerl, a prototype of a focused crawler has been realized. Experimental results indicate that Crawlerl has better performance. The number of topic web pages crawled by Crawlerl attains more than 55%. |
