Abstract: According to the characters of Web forum site such as the complex structure and quickly updating contents, an algorithm of forum incremental information sampling is presented. The technologies of site map rebuilding and estimating the frequency of page update are used. According to the site map, the crawler selects effective links. According to the frequency of Web page update, the crawler determines the crawling frequency of the Web page. Experimental results indicate this method is effective.

Key words: Web forum, incremental crawler, site map, Poisson model
