As a huge data source the internet contains a large number of valuable information, and the data of information is usually in the form of semi-structured in HTML web pages. In order to extract the web data and organize the data with the relationships which are similar to the real world, this paper has proposed a method for automatic data extraction from the web. With the combination of keywords and database content matching, the target web pages which contain valuable data will be crawled. Via HTML structure and visual features, extracting the data from the web pages crawled. Eventually, the data been extracted will be integrated to the structure of information network model. Experimental results indicate that this method can be able to apply to semi-structured data extraction in the web, and this paper has provided positive significance to extraction and manage semi- structured web data.
