摘要With the rapid development of network and information technology, there are huge amounts of data on the internet. But the major problem faced by researchers is how to filter out information on specific fields among them efficiently. In this paper, we try to build a focused crawler based on VSM (Vector Space Model) and TF-IDF (Term Frequency - Inverse Document Frequency) text correlation analysis. Particularly, we primarily take the seed URL as a collection entrance and fetch web pages from internet. Then we analyze page information though technologies, such as web content extraction, page link analysis technology. So we ultimately get the main content of the page. Through correlation analysis method based on VSM and TF-IDF, we calculate the relevance between pages and topics that have been defined, to get information we need.
