Architecture for Web Services Filtering and Clustering

The need for filtering of services results from the ever growing number of available Web services which offer similar functionalities. The filtering process is based not only on the functional aspects of services, but also on non-functional ones. One of the weaknesses of the filtering process is lack of high efficiency and its complexity as processing ontological descriptions and reasoning on them is extremely time-consuming. In order to speed-up the filtering process, clustering techniques that would narrow the set of potential services which meet users preferences may be introduced. In this article the architecture for Semantic Web services filtering and clustering system is shortly discussed.

Organisational Ontology Framework for Semantic Business Process Management

The field of Semantic Business Process Management (SBPM) has refuelled interest in using ontologies for the representation of the static and dynamic aspects of an enterprise and value chains. Putting the SBPM vision into practice, however, requires a consistent and operational network of ontologies reflecting the various spheres of enterprise structures and operations. Consistent means that the ontologies are based on compatible paradigms, have a compatible degree of detail, and include at least partial sets of alignment relations which allow data interoperability. Operational means that the ontology specifications are available in a single, current ontology formalism for which scalable repositories, reasoning support, APIs, and tools are available. In this paper, we describe a set of ontologies for SBPM that follows the mentioned requirements, and compare our work with the related efforts.

Duality in Web Services Reliability

The Web services technology allows for easy creation of complex applications consisting of smaller components - Web services. This article performs an in-depth analysis of a Web services’ reliability problem for both atomic and composite web services. Is there really a problem of low reliability for composite applications?

Semantically Annotated EPC within Semantic Business Process Management

Semantic Business Process Management (SBPM) promises bridging the gap between business and IT using machine processable enterprise models. Therefore, SBPM requires semantically annotated enterprise models in general and semantic business process models in particular. There are several well established business process modelling notations like BPMN and EPC. For SBPM to get adopted by practitioners, it must not introduce new modelling notations but instead reuse existing formalisms. Therefore, within this article we present an ontology for EPC models that may be used as their serialisation. The sEPC ontology was evaluated using competency questions and annotating a real-world business process.

Organizational ontologies to support semantic business process management

The Semantic Business Process Management (SBPM) aims at automation of the Business Process Management life cycle with use of semantics and Semantic Web services technology. The key issue to fulfil this aim is to provide an adequate machine-processable representation of processes. In this article we present one of the most important elements of process description, namely organizational ontologies. Moreover, we discuss their role in the early phases of SBPM and illustrate it with a set of application scenarios.

Procedure and guidelines for evaluation of BPM methodologies

Purpose – The purpose of this paper is to present a methodology that may be used to perform evaluation of business process management (BPM) methodologies. As this area lacks proper formalized approaches, the aim of the publication is to promote the new approach, proposed by the authors.Design/methodology/approach – The authors analyse related methodologies and theoretical background. Based on that, they suggest an evaluation approach, which is used to verify correctness of a semantic BPM (SBPM) methodology.Findings – The proposed evaluation methodology has been practically tested. Additional interviews have been conducted and interviewees stress high value of the approach. The presented evaluation methodology was validated on the example of the SBPM methodology used in a European integrated project.Research limitations/implications – The results of this paper can be used to guide development and verify correctness of new BPM methodologies.Practical implications – The paper demonstrates how validation of B...

Architecture for Service Profiling

Service oriented architecture is gaining momentum. However, in order to be successful, the proper and up-to-date description of services is required. Such a description may be provided by service profiling mechanisms, such as one presented in this article. Service profile can be defined as an up-to-date description of a subset of non-functional properties of a service. It allows for service comparison on the basis of non-functional parameters, and choosing the service which is most suited to the needs of a user. In this article the notion of a service profile along with service profiling mechanism is presented as well as the architecture of a profiling system

Semantic Web Services Applications - a Reality Check

ZusammenfassungDer Aufsatz gibt einen Überblick über den Entwicklungsstand der Technologie von Semantic-Web-Services. Im Mittelpunkt steht der Vergleich zwischen der akademischen Forschung und der tatsächlichen Akzeptanz in der Wirtschaft. Der Beitrag schließt mit einer Betrachtung der Gründe für die zögerliche Anwendung der Technologie.AbstractThis article aims at providing an overview of the current state of development of Semantic Web services technology. The focus is on a comparison between the research held in the academia and the Semantic Web services adoption in the industry. The reasons that hamper the application of this technology are also given.

Autocompletion for Business Process Modelling

This paper presents an idea and prototype of the semantic-based autocompletion mechanism supporting development of business process models. Currently available process modelling tools support business analysts by suggesting elements that may be incorporated in the process, validating modelled processes, providing additional descriptions easing automation, etc. However, these solutions based mainly on syntactic data, disregard proper identification and usage of previously modelled process fragments. The mechanism described in this paper analyses context and annotations of process tasks (also on the semantic level) in order to deliver a list of suggestions for possible successor tasks: process fragments that may complete the model being developed.

Application-oriented Web services filtering

The issue of information overload is quite well resolved in the area of textual documents available on the net by using the paradigm of information filtering. However, as the idea of applications of Internet is still changing and evolving into the more and more dynamic concept connected with the paradigm of Web services, there also appears a need for filtering of different objects. In this paper the concept of application-oriented Web services filtering is discussed. As the proof-of-concept the F-WebS (filtering of Web services) system is presented.
