| Abstract(in English) | Recent research efforts on extracting information from Web pages have mainly focused on semi-automatic and automatic approaches to generating Web wrappers. This paper aim at establishing a structure-based approach to finding a common structured pattern from semistructured data such as HTML documents and XML documents through approximate tree matching by a tree edit distance measure for generating Web wrappers. The common structured pattern is generated by finding a similarity among parsed trees of Web pages, and merging these trees by alignment of trees. Each node of the pattern tree is weighted according to its frequency of occurrence in the tree. We present a method for generating Web wrappers from manually edited Web pages including a number of grammatical mistakes in HTML, redundant or missing fragments. |
