Abstract

The invention discloses a thematic word relevance processing method and system and a thematic word recommendation method and system. The webpage thematic word recommendation method comprises extracting a plurality of thematic words from a plurality of webpages to form a target word library, and obtaining webpage content data from the plurality of webpages to form a source database; calculating the number of webpages in the source database, where every thematic word of the target word library appears; calculating the number of concurrence webpages in the source database, wherein any two thematic words of the target word library appear; according to the rules in proportion to the number of the webpages, the number of the concurrence webpages and the concurrence frequency and in inverse proportion to the difference of the number of the webpages, calculating the relevance numeric values among the thematic words. The thematic word relevance processing method and system can greatly improve the accuracy of thematic word relevance calculation.

Description

technical field [0001] The present invention relates to the technical field of networks and computers, in particular to a method and system for processing the relevance of subject words, and a method and system for recommending subject words. Background technique [0002] The exponential explosion of network information has created a huge obstacle for users to browse and filter the web pages they are interested in, which is called "information overload". How to better mine, extract and organize these web pages has become an important topic. Keyword extraction is widely used as an effective organizational means to highlight the core content of web pages. [0003] Keyword extraction solves the organization problem of a single webpage. On the other hand, it is increasingly important to associate so many webpages so that users can browse and recommend reading. The keyword correlation calculation can find keywords with similar semantics and the set of webpages they contain, so ...
