A Web data Extraction technique based on label library is proposed for extracting information from data intensive Web pages in this paper. It eliminates conception ambiguity of the contents of Web pages with the label library, mines data regions by using MDR repeated patterns discovery algorithm, recognizes their structure and extracts data from them through a novel hierarchic pattern recognition and data extraction algorithm. Experiments showed it has perfect effect.
