Ontologies are expected to play an important role in many application domains, as well as in software engineering in general. One problem with using ontologies within software engineering is that while UML, a widely used standard for specifying and constructing the models for a software-intensive system, has a four-layer metamodeling architecture, the standard OWL Web Ontology Language does not...

Semantic Web service studies are carried out around the OWL-S, however, OWL-S model does not contain the description of preferences and constraints when we choose and use them in different organizations, different cultures, different sectors and actors because of OWL capacity limitations in rules. It means that Semantic Web service composition can not compose users’ subjective services from the...

Ontology-based modeling of Clinical Practice Guidelines (CPG) is a well-established approach to computerize CPG for execution in clinical decision support systems. Many CPG computerization approaches use the Web Ontology Language (OWL) to represent the CPG’s knowledge, but they do not exploit its reasoning services to execute the CPG. In this paper, we present our CPG execution approach that le...

The Ontology Web Language (OWL) provides a powerful framework for describing the semantics and constraints of a particular domain described in RDF. Along with that power comes the burden of a learning curve that is often inherited by the tools used to manage OWL ontologies. The Manchester OWL syntax introduced an intuitive syntax for the presentation and editing of OWL ontologies that attempted...

OWL, the Web Ontology Language, provides syntax and semantics for representing knowledge for the semantic web. Many of the constructs of OWL have a basis in the field of description logics. While the formal underpinnings of description logics have lead to a highly computable language, it has come at a cognitive cost. OWL ontologies are often unintuitive to readers lacking a strong logic backgro...

This paper develops the idea of membership function assignment for OWL (Web Ontology Language) ontology elements in order to subsequently generate fuzzy rules from this ontology. The task of membership function assignment for OWL ontology elements had already been partially described, but this concerned the case , when several OWL ontologies of the same domain were available, and they were merg...

Current web services development tools are more sophisticated though ease of use, which leverage the creation of more web services thereof. This is the fact that, web services are being created and updated frequently, this multiplication of web services cannot be easily controlled by human being because it is almost impossible to analyze them and generate the composition plan. Composition of we...

BPEL4WS is a well-established business process standard that can be used to orchestrate service-based workflows. However, the rapid growth and automation demands of e-business and grid applications require BPEL4WS to provide enhanced semantic annotations to achieve the goal of business processes automation. Here, OWL-S (OWL for Web Services) is designed to represent such kind of semantic inform...
