HPG: a tool for presentation generation in WIS

Abstract

Web Information Systems (WIS) support the process of retrieving information from sources on the Web and of presenting them as a hypermedia presentation. Most WIS design methodologies focus on the engineering of the abstract navigation (hyperlinks). The actual presentation generation is less supported. Hera is one of the few WIS methodologies that offer a tool for presentation generation (HPG). The HPG transforms RDF data obtained as the result of a query into a Web presentation suited to the user (in HTML or WML).
