Semantic Extraction from List Web Pages
Extracting structured information from web pages is a problem that has many applications and that gained increased interest in recent years.
We propose an approach that can achieve extraction and semantic description of data contained in a list web page. Our approach is fully automatic and is based on a \seed\ ontology that contains minimal information about the domain. It uses an instance-based classifier to characterize the attributes of the ontology. In opposition to existing methods, our approach does not make any assumption on the design of web pages ; it is totally layout independent.
Experimental results obtained from different web pages of different web sites from different domains show that our approach is effective.
