Semantic Web Services and Goals

905 Words2 Pages

In this section, we present the service discovery scenarios to evaluate and compare the current web services technology with our proposed framework for semantic web services using existing telecommunication industry data. The evaluated results are based on prototype implementation, using sample data of a leading telecommunication operator in Pakistan, which has its distributed computer centres in nine different cities of Pakistan (name is not cited for privacy conditions).

We performed a typical process of interconnect settlement service discovery. Service have been composed on the bases of agreed rates of billing, subsequently performed all the required configuration which includes number series, trunks, and tariffs selection. We have used bottom-up approach for services creation, given that the billing service providers have WSDL description with web services. According to [29], WSMO offers a model with formal language WSML that describes aspects of Web services.

Ontologies: show the key element in WSMO, offers common terminology used by other WSMO elements and also describe the semantic properties of relations, concepts and set of axioms.

Web Service: interchanges data and couples data in new ways. It also explains the functional, non-functional and behavioural aspects

Goals: donates the aims of the client

Mediators: controls the semantic, structural or conceptual divergence between different components. It can automatically handle interoperability problems.

Semantic Web Services and Goals are explained with reference to the definition of WSMO service and WSMO Goal. Although they have the same structural definition, they differ in representation [11] as depicted in figure 5. Service discovery based on our propo...

discovery. We have projected an integrated framework composed of WSMX and IRS-III that can efficiently

handle excessive volume of telecommunication services. Projected framework along with its components is discussed in detail.

Our current and future work is oriented to further harness our ontologies with the help of professional telecommunication engineers and domain experts. We are conscious of the challenges ahead that semantic web services could confront particularly during execution in a broad-based industrial applications and hence working on to lessen them. Moreover, we are focusing to figure out further drawbacks and challenges of the semantic web services. More efforts are being made to make the semantic web service in perfect resonance with the modern needs and challenges in order to make it highly dynamic intelligent business application.
