Information Extraction from Web Pages
Róbert Novotný, Peter Vojtáš, Duan Maruscak · 2009
We present a chain of techniques for extraction of object attribute data from web pages which contain either multiple object data or detailed data about a single object. We discover data regions containing multiple data records, which will be extracted with help of extraction ontology. Furthermore, we present an additional algorithm for detail-page extraction based on the comparison of two HTML subtrees.
