Abstract
In order to implement the information fusion ofelectronic products, the widely adopted approach is toextract information from HTML structure of businessWebsite with deeply data processing. However, modelingWeb application is hard to be solved that the data in HTMLis semi-formal which displayed as DOM (Document ObjectModel) tree when using XML schema to data analysis. Howto understand and extract information is first to beresearched. The general model Anchor-Hop considering thetext property and label property is simple to handle thisproblem. Therefore, it has low effectiveness. This model issensitive to the data of HTML structure, that if the websitestructure is slightly changed the issue of extraction accuracyis encountered. As a result, the extraction rules should beredefined because of the changed structure. In order toimprove extraction efficiency, this paper proposed a DOMbaseddynamic model Anchor-Hop-T information extractionmodel. The HTML tags including table, ol and ul can besearched and processed using XPath so that it isconvenience to extract corresponding Anchor data block.Furthermore, the location of Hop point is considered asinvariant, by which our new model based on Anchor andHop point introduces more concepts for extractinginformation, such as Anchor data block, Anchor locatinglibrary and AH relevance value. Finally, we try to give outan experiment to demonstrate the applicability of ourapproach.
