Web Forums have been one of dominating ways for information release and exchange in Internet. Crawling is the groundwork of searching and mining information from Web Forums. However, traditional crawling component usually using “Broad-first” strategy can not fetch information from Web Forums effectively. Exploring inner structure-features of forums, this paper presents a crawling strategy, which is based on “board-topic correlation judgments” algorithm. Compared with “board-first” strategy, this solution performs remarkably better both in precisions and recall. In practice, the algorithm is performed over 12 000 different Web forums and achieves a good result.
