The current trends for the future evolution of the Web are without doubt the Semantic Web and Web 2.0. A common perception for these two visions is that they are competing. Nevertheless, it becomes more and more obvious that these two concepts are complementary. Towards this perspective, in this work we introduce an application based on a 3-tier architecture that illustrates the potential for combining...
Previous work on addressing the problems of scalability and limited autonomy of data sources arising from the semantic heterogeneity of peer schema has proposed a layered model/approach of ontology integration consisting of peer and coalition ontology and the mapping between them. In particular, the integration model for achieving semantic interoperability in Data and Knowledge Systems (DAKS) is accompanied...
The objective of knowledge integration is to promote knowledge collection, sharing and retrieval in distributed and heterogeneous environment. Our workgroup develops a domain-oriented model for knowledge integration in distributed heterogeneous environment such as semantic grid, which promises better access to relevant knowledge by producing a global domain ontology that is used for establishing semantic...
The grid is emerging as a wide-scale distributed computing infrastructure that promises to support resource sharing and coordinated problem solving in dynamic multi-institutional virtual organizations. To describe data, the Web service issues have been extended with a relevance of grids in education. To successfully summarize this in terms of a Web service implementation strategy for a hypothetical...
This paper describes a methodology that providers of services can use to adapt their software applications, both intra-net and inter-net systems, to the changes of their business environment. The methodology enables agile software development based on a Web process architecture that executes ontology-based business processes as workflow systems. Ontology construction technology is used to extract...
Multi-agent systems (MAS) which communicate with intra-domain and inter-domain agent platforms have access control requirements. Instead of a central mechanism, a fine-grained access control mechanism could have been applied to MAS platforms. This paper emphasizes MAS-based domain and security ontologies with XACML-based access control approach for MAS platforms. The domain dependent behaviour and...
Nowadays, application systems in pervasive computing have to be self-adaptive, which means adapting themselves to dynamic environments. Our aim is to enable systematic development of self-adaptive component-based applications. The paper first introduces a novel policy based framework for self-adaptive scheme in pervasive computing. Then the proposed policy ontology and policy language are well expressive...
This paper describes a methodology that enterprises can use to adapt their software applications, both intra-net and inter-net systems, to the changes of their business environment. The methodology enables agile software development based on a Web process architecture that executes ontology-based business processes as workflow systems. Ontology construction technology is used to extract business model...
In this paper we present a novel software architecture (ArUC) to simplify the development of ubiquitous systems, providing a set of fundamental services that have been identified as useful and desirable for any ubiquitous system. This architecture solves the three main issues related to spontaneous interoperability (initialization, discovering and interaction). To solve them we have developed a set...
While software design patterns have been proposed for a wide variety of software domains, surprisingly little has been done to formalize an online assessment methodology. In other words, how does one assess a software engineerpsilas learning of a particular design pattern? This paper presents a framework and a tool motivated by Bloompsilas Taxonomy that extends an existing OWL ontology for design...
A method framework for SCOR (Supply Chain Operations Reference model) was designed. SCOR contains three levels of process details: using UML to model the process in level 1 and the domain ontology, using XML Nets, a kind of high level Petri Nets to model the process categories in level 2 and to assemble the XML Nets fragments according to the request ldquoconfigured-to-orderrdquo, and using Xml Nets...
Knowledge representation is a multidisciplinary subject that needs to apply theories and techniques from logic, ontology and computation. There are a great number of languages able to represent knowledge, among them UML can be considered a suitable language for modelling knowledge. It could be included within the category of visual languages for knowledge representation. On the other hand, numerous...
Current fashion systems to interconnect large software architectures are moving toward SOA based solutions. This new paradigm for designing system can be improved, in our opinion, by using semantics. Semantics can a play a main role in boosting interoperability thanks to current technologies to express knowledge and to describe semantic Web services (SWS). This paper tackles the provision of a Software...
