Current methods for the information extraction from HTML documentsare mostly based on wrappers that read the HTML code and identify thedata to be extracted by some properties of the surrounding HTML tagsand the text. The bottleneck of this approach is too tight binding ofthe wrapper to the HTML code. The nature of HTML allows to achieve thedesired document design by various ways that can be arbitrarilycombined, which makes the wrappers limited to a narrow set of documentsand a short time period. By contrast, there exist some generallyaccepted rules for the visual data presentation in the documents. Ourapproach is based on using the visual information for identifying thedata in the documents. We define formal models of the visualinformation and we propose the method for information extraction basedon the unordered tree matching algorithms.
