In order to conduct in-depth study of flexible R&D platform for solar concentration photovoltaic system, the author proposes the design method for flexible R&D platform for solar concentration photovoltaic system based on ontology and knowledge fusion. This paper explains the integration concept of flexible R&D platform, explores the way of acquiring and expressing multi-source knowledge...
Current IEC 61131-3 programmable logical controllers are facing challenges to provide reliable system as well as exceptional performance for complex distributed automation systems. The IEC 61499 standard is designed to cover interoperability not only on the runtime level, but also during the design process. To migrate from IEC 61131-3 PLC to IEC 61499 function blocks, there are several approaches...
Facing global competition in the chemical industry particular companies from high-wage countries have to cut development costs and time to market to be still profitable. Therefore, methods like concurrent and collaborative engineering are increasingly applied. However, these complex workflows require adequate software support to be efficient in face of heterogeneous software environments as typically...
The geographic information service applications are getting more and more closely interconnected with the real-time industries and businesses recently. It becomes an urgent problem to gather business information from various industries directly. In this paper, we present an ontology-based dynamic data gathering method of geographic information services, which can extract instant information from MIS...
Recently ontologies have drawn much attention from research communities. However, the advantage of using ontologies for knowledge-driven intelligent query answering is yet to be fully explored. In this paper, we examine the use of ontologies for guiding XML query relaxation and propose a practical approach which incorporates WordNet ontology with free software Qexo. Rather than reinventing the wheel,...
Ontologies in the Software Engineering domain can improve the acquisition of knowledge in this field by providing a formal representation of this knowledge domain. When encoded in a XML-based format, ontologies can therefore be easily processed by a knowledge management system, an expert system or a browser so it is possible to facilitate the location of Software Engineering resources in repositories...
The contemporary Web is heading towards its next stage of evolution. From a clump of unorganized information spaces, the Web is becoming more focused on the meaning of information that is a Semantic Web. Trust is an integral component in semantic web, allowing people to act under uncertainty and with the risk of negative consequences. In this paper we discussed trust management and its connection...
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...
Manufacturing plants need to be flexible and evolvable, which might be achieved by stepping up the level of abstraction at which they are designed. In this work a methodology that starts by creating ontologies of the plants that represent information flows is proposed. Agent-based technology is then used to provide systems with the ability to evolve. The proposal is designed to suit the needs of SME'...
Complications related to volume increase of data that needs to be analyzed, lack or insufficiency of complementary metadata and task of transforming data to ontologies in this context are described. Applications with declarative approach for solving task of transforming arbitrary located data in any available format to ontological representation are examined. Relevant languages and technologies are...
In a previous work we presented an approach to allow invocation of services whose interface and behavior differ from each other. Such approach requires the definition of scripts by some human being able to completely understand the mismatches and properly combine the mapping functions. Furthermore, such approach requires an intensive effort from a system integrator that, in the worst case in which...
The paper introduces the key technology of the semantic Web and methods of the software component description. After the analysis of the description of facet components and the description of formal methods, the author puts forward the Ontology Component Description model based on the Semantic Web. After the analysis and comparison this model with others, component representation based on Ontology...
The World Wide Web's constant growth and transformation offers great opportunities - and poses many challenges for exploitation. In our information-exploded times, it has been a hot problem that how to improve precision and recall of the content we want to search. After analyze the limitations of traditional method, bring a semantic search forward, and mainly introduce the thought of the semantic...
This paper introduces AccessOnto, an ontology-based toolkit for accessibility requirements specification primarily designed to provide a repository of accessibility guidelines and plus a specification language intended to help software developers to incorporate accessibility requirements in their user requirements document. Currently specification of accessibility requirements is largely based on...
The distributed structure of agents makes the test for large and complex Web service composition possible. This paper discusses how to develop the multi-agent test environment for BPEL-based Web Service composition. The BPEL-based Web Service composition is modeled by HPN that can be easily referenced by test case generation and test evaluation. By representing agent in HPN, the agent can be dynamically...

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...
Ontologies provide an explicit representation of concepts and their relationships, which provides a strong context for the use and manipulation of data within a problem domain. If the data is referred to without the ontological framework, any association with its original context is lost. A complex system may be implemented with several, different, programming languages and, while an ontological description...
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...
With advances of digital technology two or more organizations form a federation for a temporary purpose. It is possible that an employee of an organization needs to access resource of another organization. While languages like XACML are very good for access control of a single organization, they are not able to address interoperability issues of such federations. Lack of interoperability of access...
