چکیده

Existing approaches for querying OWL DL do either only operate on syntactic constructs without taking into account the semantics of OWL or do only have a restricted access to the T-Box. We present OWL-SAIQL, the novel Schema And Instance Query Language for OWL DL, that is well suited for ontology extraction. We describe its syntax and provide a model-theoretic semantics for OWL-SAIQL. Furthermore, we explain a basic evaluation strategy for OWLSAIQL queries that is a suitable basis for optimization techniques known from database management systems. We illustrate the use of OWL-SAIQL with an example of ontology extraction and re-use.

A Protégé Plugin for Querying and Reasoning on Persistent OWL Ontologies

The OWL language [1] is being widely used to define ontologies in the Web. This language provides three increasingly expressive sublanguages, namely OWL Lite, OWL-DL and OWL Full. The OWL-DL XML based syntax together with its correspondence with Description Logics (DL) [2], make it a good candidate to be the standard language for defining ontologies used by Semantic Web applications. However, t...

WSML Deliverable D 20 . 1 v 0 . 2 OWL −

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 the deductive database language Datalog. Thus, any OWL Lite− or OWL...

On the Containment of SPARQL Queries under Entailment Regimes

Most description logics (DL) query languages allow instance retrieval from an ABox. However, SPARQL is a schema query language allowing access to the TBox (in addition to the ABox). Moreover, its entailment regimes enable to take into account knowledge inferred from knowledge bases in the query answering process. This provides a new perspective for the containment problem. In this paper, we stu...

D4.2.2 Ontology customization and module creation: query-based customization operators and model

This deliverable presents a prototype of a technique for realizing ontology customization operators, which can be used to propose to the user a personalized view on an ontology for his/her current task or his/her job. This prototype is based on a query language specifically designed to cope with more expressive ontologies. Thus, this deliverable also introduces this new query language for OWL-D...
