Section III: Techniques and Tools
In this section we introduce some of major techniques and tools developed in the
domain of ontology building and analysis and Semantic Web.
Chapter V, “A Tool for Working with Web Ontologies,” by Kalyanpur, Parsia, and
Hendler, presents a tool (SWOOP) for building, modifying and searching ontologies.
SWOOP is a stand alone application program to work with OWL ontologies.
The authors discuss some insights into Web ontologies that were gained through
the experience with SWOOP, including issues related to display, navigation, editing
and collaborative annotation of OWL ontologies.
Chapter VI, “An Ontology-Based Multimedia Annotator for the Semantic Web of
Language Engineering,” by Chebotko, Deng, Lu, Fotouhi, and Aristar, present an
ontology-bases linguistic multimedia annotation tool called OntoELAN. The tool
features:
• The support for OWL ontologies
• The management of language profiles that allow the user to choose a subset
of ontological term for annotation
• The management of ontological tires that can be annotated by language profile
terms and therefore, corresponding ontological terms
• Storing OntoELAN annotation documents in XML format based on multimedia
and domain ontologies
Chapter VII titled “A Layered Model for Building Ontology Translation Systems,”
authored by Corcho and Gómez-Pérez, presents a model for building ontology
translation systems between ontology languages and/or ontology tools.
Although there is a growing literature on ontology translation (and significant
earlier literature on related topics of schema mapping and translation), the broader
perspective of this chapter comes from considering four different layers: lexical,
syntax, semantic, and pragmatic. This issue also proposes a method that guides in
the process of developing ontology translation systems based on four main activities:
feasibility study, analysis of source and target formats, design, and implementation
of the translation system, and recommends the techniques to be used inside each
of them.
Chapter VIII, by Bry et al., is titled “Querying the Web Reconsidered: Design Principles
for Versatile Web Query Languages.” In this chapter the authors provide a
milestone based on an experience with research, standardized query languages for
