This paper presents a new system to automatically recognize fishes based their digital pictures. The system follows the requirement of SOA (Service Oriented Architecture) in order to provide a self-service platform for public. The system provides services like the training mode, the recognition mode, and the consulting mode. These services can be deployed onto various application servers at different...
Nowadays, with the rapid development of Web services technologies as a solution to achieve SOA, the number of Web services on the web that offer similar functions is increasing. Therefore, not only the discovery and selection of the best Web services based on functional property requirements and preferences of users is not sufficient, but also owning to improve and achieve more accurate results, the...
Resource management in distributed and heterogeneous databases is an urgent problem nowadays. In this paper, a framework is proposed to give an efficient method to solve this problem. This framework has two main parts. First, the Web service architecture is given by analyzing many metadata standards and databases. By using Web service technology, the ontology-based framework of is proposed to address...
Web Service Description Language and Universal, Discovery and Description Integration (UDDI) describe Web Services in a syntactical way and are helpful in their search, but they miss a semantic description of their specific conceptual domain. The search for services using solely a syntactical base may result in available services that donpsilat match the expected context, decreasing the accuracy of...
The growing amount of distributed data over the internet leads to increasing needs for interoperability. Being able to take into account the meaning of information is a real challenge for suitable data sharing. The semantic web and the ontologies are relevant technologies to provide semantic cooperation of heterogeneous sources. We propose a complete architecture OWSCIS (Ontology and Web Service based...
In this paper we propose a way to facilitate the issue of discovering the eGovernment services that address a citizen's need. This approach is implemented in an application, which we call a semantic portal. The semantic portal is part of our SemanticGov project architecture. The portal's components and its architecture are presented and explained. The portal's conceptual modeling is based on the generic...
