Our initial tasks were to select a semantic language to model our ontologies (local
and shared global ontologies), select an ontology editor to construct, browse, and
manage the ontologies under development, and adopt a methodology to develop
the ontologies. These tasks are described in the following sections.
Ontology Language Selection
Several languages have been developed to support the Semantic Web. These structured
languages can carry meaning besides giving structure to data. Some languages are
more directed to providing meaning to data, while others go further and can make
assertions and infer knowledge.
In this area, the major developments are being made by an international Semantic
Web research activity, spearheaded by the World Wide Web Consortium (W3C)
(www.w3.org) and the Defense Advanced Projects Research Agency (DARPA)
Agent Markup Language (DAML, 2005) program. The newest languages are developed
based on the progress from previous ones, evolving and improving their
characteristics. The most relevant semantic languages that need to be considered
for developing ontologies for e-tourism are the following:
