Data quality issues have taken on increasing importance in recent years. In our research, we have discovered that many “data quality” problems are actually “data misinterpretation” problems – that is, problems with data semantics. In this paper, we first illustrate…

We show how to interoperate, semantically and inferentially, between the leading Semantic Web approaches to rules (RuleML Logic Programs) and ontologies (OWL/DAML+OIL Description Logic) via analyzing their expressive intersection. To do so, we define a new intermediate knowledge representation (KR)…

We address the problem of integrating objects from a source taxonomy into a master taxonomy. This problem is not only pervasive on the nowadays web, but also important to the emerging semantic web. A straightforward approach to automating this process…

A series-parallel directed acyclic graph, or SP-dag, contains nodes that are either in series or logically in parallel. We present a data structure and algorithm to efficiently determine, in a single serial walk of the dag, whether two nodes are…

Naïvement perçu, le processus d’évolution est une succession d’événements de duplication et de mutations graduelles dans le génome qui mènent à des changements dans les fonctions et les interactions du protéome. La famille des hydrolases de guanosine triphosphate (GTPases) similaire…

Nowadays universities are required not only to impart
knowledge of specific disciplines but also generic graduate
attributes such as communication, problem-solving,
teamwork, creative thinking, research and inquiry skills. For
students to attain these generic skills, educators are
encouraged to use…

It has been suggested there is a knowledge base that surrounds the use of 3D modeling within the engineering design process and correspondingly within engineering design graphics education. While solid modeling receives a great deal of attention and discussion relative…

The present article examines how practices of computersupported
collaborative designing may be implemented in
an elementary classroom. We present a case study in
which 12-year-old students engaged in architectural design
under the guidance of their teacher and a professional
designer.…

In this article we develop a measure to approximate the diffusion of product-embodied R&D that takes place by means of the intermediate purchases of KIBS in 19 of the EU27 countries over the period 2000-2005. The results obtained confirm a…
