Adaptive Web Data Extraction Method
摘要
Abstract
According to the web page extraction,an adaptive web data extraction method based on extraction template was proposed.The adaptive web extraction process was given.The extraction rules and the adaptive search rules were de-fined,the matching method of the web page and the extraction template was presented,and the process of target data search and extraction template adaptive repair was described in details.Experimental results showed that the recall rate and preci-sion rate were more than 95%,and the method can effectively reduce the quantity of extraction templates.关键词
