Abstract

The invention provides a system and method for extracting webpage kernel contents, and the system receives HTML documents (web pages) and extracts the kernel contents, and comprises: text block analyzer for using HTML label as delimiter to divide the text fragments in each available basic structure in the input HTML documents into one or plural independent file blocks and in order connecting all the file blocks together to output, where the available basic structure comprises webpage kernel contents; and text block checker for removing the file blocks without the kernel contents and outputting the rest as the webpage kernel contents. The invention determines if each file block contains advertisements and navigation information, thus able to accurately determine the webpage kernel contents and also raises the processing efficiency.

Description

technical field [0001] In general, the present invention relates to a system and method for extracting core content of a web page and a computer program product for realizing the method. Specifically, the present invention relates to a system and a method for extracting the core content of a webpage by using the layout of the webpage and a computer program product for realizing the method.
