Authoring OWL 2 ontologies with the TEX-OWL syntax

W3C …, 2009

The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF,

Web Semantics: Science …, 2008

Since achieving W3C recommendation status in 2004, the Web Ontology Language (OWL) has been successfully applied to many problems in computer science. Practical experience with OWL has been quite positive in general; however, it has also revealed room for improvement in several areas. We systematically analyze the identified shortcomings of OWL, such as expressivity issues, problems with its syntaxes, and deficiencies in the definition of OWL species. Furthermore, we present an overview of OWL 2-an extension to and revision of OWL that is currently being developed within the W3C OWL Working Group. Many aspects of OWL have been thoroughly reengineered in OWL 2, thus producing a robust platform for future development of the language.

We present an approach for mapping an OWL ontology into Java. The basic idea is to create a set of Java interfaces and classes from an OWL ontology such that an instance of a Java class represents an instance of a single class of the ontology with most of its properties, classrelationships and restriction-definitions maintained. We note that there exist some fundamental semantic differences between Description Logic (DL) and Object Oriented (OO) systems, primarily related to completeness and satisfiability. We present various ways in which we aim to minimize the impact of such differences, and show how to map a large part of the much richer OWL semantics into Java. Finally, we sketch the HarmonIA framework, which is used for the automatic generation of agent systems from institution specifications, and whose OWL Ontology Creation module was the basis for the tool presented in this paper.

With the deep research of semantic Web, people are more and more concerned with the problem of representing and retrieving information content on the Web. The ontology language layer building on top of RDF schema is used to formally describe the meaning of ...

The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF, and OWL 2 ontologies themselves are primarily exchanged as RDF documents. The OWL 2 Document Overview describes the overall state of OWL 2, and should be read before other OWL 2 documents.

We present the latest version of WebProtégé: a free, opensource Web-based tool for editing OWL ontologies. WebProtégé allows users to create, upload, share and collaboratively edit OWL ontologies. It contains various tools that are designed to support collaborative editing processes, including issue discussion, complete change tracking support and watches. Besides providing complete OWL 2 editing capabilities, WebProtégé also features a default simplified user interface that is targeted at OWL neophytes. This simplified interface, which we have designed using empirical techniques, offers a quick and easy way to edit commonly used OWL 2 axiom and class constructors. In this paper we describe these features and the main ideas behind the tool. WebProtégé is available for use at http://webprotege.stanford.edu.

In this paper we introduce LODE, the Live OWL Documentation Environment, an online service that automatically generates a human-readable description of any OWL ontology (or, more generally, an RDF vocabulary), taking into account both ontological axioms and annotations, and ordering these with the appearance and functionality of a W3C Recommendations document. This documentation is presented to the user as an HTML page with embedded links for ease of browsing and navigation.
