The renaissance stimulated by the field of Computer Science is generating multiple formats and channels of communication and creativity. IJACSA is one of the most prominent publications in the field and engaging the ubiquitous spread of subject knowledge with effectiveness in all classes of audience. Nevertheless, the promise of increased engagement requires that we consider how this might be accomplished, delivering up-to-date and authoritative coverage of advanced computer science and applications. The journal has a wide scope ranging from the many facets of methodological foundations to the details of technical issues and the aspects of industrial practice. It includes articles related to research findings, technical evaluations, and reviews. In addition it provides a forum for the exchange of information on all aspects. The editorial board of the IJACSA consists of individuals who are committed to the search for high-quality research suitable for publication. These individuals, working with the editor to achieve IJACSA objectives, assess the quality, relevance, and readability of individual articles. The contents include original research and innovative applications from all parts of the world. This interdisciplinary journal has brought together researchers from academia and industry as well as practitioners to share ideas, problems and solutions relating to computer science and application with its convergence strategies, and to disseminate the most innovative research. As a consequence only 29 % of the received articles have been finally accepted for publication.

This paper presents a directory of heterogeneous web services, which addresses the issue of service discovery involving heterogeneous description languages such as OWL-S, SAWSDL, WSDL and plain text. Service descriptions are mapped into a unified description model, which captures various important elements in different service description approaches. Our directory then performs service registration, automatic discovery and manual browsing utilizing these unified models. A preliminary evaluation shows a satisfying result.

Abstract—Service-oriented architectures (SOAs) provide a successful model for structuring complex distributed software systems, as they reduce the cost of ownership and ease the creation of new applications by composing existing services. However, currently, the development of service-oriented applications requires many manual tasks and prevailing infrastructure is often based on centralized components that are central points of failure and easily become bottlenecks. In this paper, we promote self-organizing SOA as a new approach to overcome these limitations. Self-organizing SOA integrates research results in the areas of autonomic and serviceoriented computing. We consider self-organizing features for the whole life-cycle of a service-oriented application, from the creation to the execution, optimization, and monitoring.
