Framework of integrated Semantic Web Services and Ontology Development for Telecommunication Industry

The concept of web services is loosely coupled, location transparent, and protocol-independent software system for distributed platform. Literature review indicates that existing web services content is composed for humans to read whereas Semantic Web Services (SWS) have emerged as a new paradigm for meaningful data retrieval in a distributed environment. SWS have automated the information processing by interpreting human and machines content comprehensively. Telecommunications industry with its increasing demand of services and adapting nature of frequent changes forces service providers to support automated service discovery for cutting cost and response time. The objective of this paper is not only to overcome the existing limitation of automated discovery for heterogeneous and homogenous services in one model for industrial application as discussed in this paper but also to provide a way for an integrated enhancement of semantic web services. The proposed framework is an integrated approach for enhancement for goal based services discovery for telecommunication industry. We have developed domain and billing application ontologies and a prototype to validate the proposed framework by integrating Web Service Execution Environment (WSMX) and Internet Reasoning Service (IRS-III).

Evaluation of Semantic Web Services: Before and After Applying in Telecommunication

Semantic web services (SWS) have emerged as a new paradigm for meaningful data retrieval in a distributed environment. Literature review reveals that SWS have automated the information processing which was missing in current state-of-the-art technologies. This paper investigates that as an application moves from single tenant to multi-tenancy, it substantially increases the volume of homogenous as well as heterogeneous services, thereby making service discovery much more complicated. It is for these reasons this research work intends to overcome the drawbacks of services discovery with the integration of semantic technologies. We present a goal based service discovery framework offers semi- automated service discovery of homogenous as well as heterogeneous services from huge volume of services. Based on the proposed framework novel application and domain ontologies are created. A prototype system was also developed, which validated the proposed framework by integrating Web Service Execution Environment (WSMX) and Internet Reasoning Service (IRS-III). Finally, it presented preliminary results of experiential evaluation based on services discovery and mediation scenarios. Results demonstrate that by considering proposed approach required time in service discovery, and human efforts can be reduce.

WSMXDiscoCast: a P2P approach for a better automation of the discovery mechanism for web service execution environment

Semantic web services aim to automate the use of web services by adding some annotations to these services in order to improve semantic expression of their functionalities. With the evolution of organisations web services and their widespread use, searching for them based on a distributed context has become a real challenge. A functionality-based web service discovery mechanism is then necessary since the functionalities are the most important thing partners look for. In this paper, we present an automatic, scalable, and distributed discovery mechanism for web service execution environments. Our solution is based on P2P technologies that proved their efficiency and robustness as distributed systems.

Modeling Semantic Web Services with the Web Service Modeling Toolkit

The lack of any methodology for modeling Semantic Web Services means that developers wishing to utilize technologies like the Web Service Modeling Ontology, the Web Service Modeling Language, and the Web Service Execution Environment are lost in a Semantic wilderness with no road signs to guide them on their way. This paper presents an initial guide for developers wishing to model Semantic Web Services, along with a description of the Web Service Modeling Toolkit that provides tool support for the activities that must be conducted by the developer in this process.

A semantic web service environment for B2B and B2C auction applications within extended and virtual enterprises

Existing web services specifications lack an appropriate semantic framework for the creation and operation of emerging manufacturing systems such as the supply chains and extended/virtual enterprises (EE/VE) in order to execute business processes over internet. Semantic web services (SWS) technology aims to add sufficient semantics to the specifications and implementations of web services to make possible the (automatic) integration of distributed autonomous systems, with independently designed data and behaviour models. Defining data, behaviour and system components in a machine understandable way using ontologies provides the basis for reducing the need for humans to be in the loop for routine system integration processes. In this paper we present the design and implementation of a unique bid auction application for procurement automation within supply chains embedded in extended and virtual enterprises. We show how emerging semantic web services technologies such as the web services execution environment (WSMX) facilitate the creation of such applications, and we discuss the advantages of such applications.
