Generating topic maps from XML/XSD documents

Abstract

Over the years, XML has become a prominent standard for data exchange on the Web. Although XML can support syntactic inter-operability, problems arise when data sources represented as XML documents are needed to be integrated. The reason is that XML does not support sharing of concepts. This issues can be overcome by having suitable ontology representations of XML documents. The Semantic Web languages can play an important role here as they support ontology representation. Topic Map is a Semantic Web formalism (an ISO standard) for knowledge representation and interchange with an emphasis on navigation and retrieval of information. In this work we propose a framework for automatically generating Topic Map ontology from XML. We make use of XQuery and Tolog to validate our method. We illustrate our technique on examples. We also provide performance measures of our approach on some standard data sets.
