Time, as a phenomenon, has been in the focus of scientific thought from ancient times. It
continues to be an important subject of research in many disciplines due to its importance as …

This paper presents an empirical study that investigates the extent to which the pragmatic
quality of ontology-driven models is influenced by the choice of a particular ontology, given a …

An important challenge in the Knowledge Representation area is on representing and
reasoning over temporally changing information. Particularly, a number of authors have …

Temporal representation and reasoning are important facets in the design of many Semantic
Web applications. Several approaches exist to represent and reason about precise temporal …

In the first part of this paper, we present a framework for enriching arbitrary upper or domain-
specific ontologies with a concept of time. To do so, we need the notion of a time slice …

Representing temporally-changing information becomes increasingly important for
reasoning & query services defined on top of RDF and OWL, and for the Semantic Web/Web …

Representing time-dependent factual knowledge in RDF and OWL has become increasingly
important in recent times. Extending OWL relation instances or RDF triples with further …

Process ontologies play key roles in semantic integration and decision support systems for
applications in manufacturing, enterprise modeling and e-commerce. In this paper, we …

Temporal encoding schemes using RDF and OWL are often plagued by a massive
proliferation of useless “container” objects. Reasoning and querying with such …

This paper describes work carried out in the European project TrendMiner which partly
deals with the extraction and representation of real time information from dynamic data …
