The OWL Full/DL Gap in the Field

چکیده

OWL 2 Full remains a “catch all” language in the sense that it treats as well formed any legal RDF graph. In contrast, OWL 2 DL, and its sub profiles, exclude large classes of RDF graphs as malformed and thus meaningless. Many ontology documents on the web appear to fall under OWL Full. However, not all ways of being OWL Full are indicative of modelling intent. In this paper, we look at the prevalence of OWL 2 DL violations in a large corpus of ontologies gathered from the Web. We present a new classification of violations and analysis of those that are safely repairable. We find that a high preponderance (69%) of violations are repairable and are, indeed, mainly “mere” declaration failures. This suggests for example that declarations as a conformance criterion should be rethought.

WSML Deliverable D 20 . 1 v 0 . 2 OWL − WSML Working Draft – January 6 , 2005

This deliverable presents restricted variants of the OWL Lite, DL and Full species of the OWL ontology language, called OWL Lite−, OWL DL− and OWL Full−, respectively. OWL Lite− and OWL DL− are strict subsets of OWL Lite and OWL DL. They are limited in such a way that there exists a translation from both languages directly into dunction-free logic programs, i.e., Datalog. Thus, any OWL Lite− or...

OWL DL: Trees or Triples?

The Web Ontology Language (OWL) defines three classes of documents: Lite, DL and Full. All RDF/XML documents are OWL Full documents, some OWL Full documents are also OWL DL documents, and some OWL DL documents are also OWL Lite documents. This paper discusses parsing and species recognition – that is the process of determining whether a given document falls into the OWL Lite, DL or Full class. ...

Filling the Gap between OWL 2 QL and QuOnto: ROWLKit

Ontologies are nowadays one of the most prominent formalisms used in the area of Semantic Web for knowledge representation. Several efforts have been made by the W3C in order to define OWL (Web Ontology Language) and by developers in order to develop reasoners able to deal with ontologies defined by means of OWL. Unfortunately, the goals of the working groups for standard languages definition r...

Using Vampire to Reason with OWL

OWL DL corresponds to a Description Logic (DL) that is a fragment of classical first-order predicate logic (FOL). Therefore, the standard methods of automated reasoning for full FOL can potentially be used instead of dedicated DL reasoners to solve OWL DL reasoning tasks. In this paper we report on some experiments designed to explore the feasibility of using existing general-purpose FOL prover...
