This paper introduces primarily a core Algorithm of Web topic information gathering system that we designed——the Forecast URL-Topic Algorithm. It bases on the related theories, analyzes the experiment data and discovers the topic of the hyperlink be decided by three factors primarily: the topic Similarity of the parent Web page, the topic Similarity of the (ex-)anchor text and the structure characteristic of Web graph, then puts forward the algorithm of Forecasting URL-Topic based on Web structure and Web page contents, the system evaluation result shows that the algorithm has great efficiency.

Key wordsWeb structure      Hyperlink      Topic      Forecast      Algorithm
