Solving problems raised by heterogeneous ontologies can be achieved by matching the ontologies and processing the resulting alignments. This is typical of data mediation in which the data must be translated from one ...

This paper summarizes the necessities on the semantic modeling of Web Service constraints and capabilities from the viewpoint of the Web Service Modeling Ontology(WSMO) working group. We will give a short motivating use ...

RDF Schema (RDFS) as a lightweight ontology language is gaining popularity and, consequently, tools for scalable RDFS inference and querying are needed. SPARQL has become recently aW3C standard for querying RDF data, ...

The paper introduces basic features of a novel ontology integration framework that explicitly takes the dynamics and data-intensiveness of many practical application scenarios into account. We motivate our research partially ...

The paper presents a novel ontology lifecycle scenario that explicitly takes the dynamics and data-intensiveness of real world applications into account. Changing and growing knowledge is handled by semi-automatic ...

In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...

Knowledge domains and their semantic representations via ontologies are typically subject to change in practical applications. Additionally, engineering of ontologies often takes place in distributed settings where multiple ...

Knowledge domains and their semantic representations via ontologies are typically subject to change in practical applications. There- fore, especially in distributed environments, change management for ontologies becomes ...
