Abstract:
This Ontologies are widely used as a means for
solving the information heterogeneity problems on the web
because of their capability to provide explicit meaning to the
information. They become an efficient tool for knowledge
representation in a structured manner. There is always more
than one ontology for the same domain. Furthermore, there is no
standard method for building ontologies, and there are many
ontology building tools using different ontology languages.
Because of these reasons, interoperability between the ontologies
is very low. Current ontology tools mostly use functions to build,
edit and inference the ontology. Methods for merging
heterogeneous domain ontologies are not included in most tools.
This paper presents ontology merging methodology for building a
single global ontology from heterogeneous eXtensible Markup
Language (XML) data sources to capture and maintain all the
knowledge which XML data sources can contain.
