Abstract

We present a general framework for information extraction from web pages based on a special wrapper language, called token-templates. By using token-templates in conjunction with logic programs we are able to reason about web page contents, search and collect facts and derive new facts from various web pages. We give a formal definition for the semantics of logic programs extended by token-templates and define a general answer-complete calculus for these extended programs. These methods and techniques are used to build intelligent mediators and web information systems.
