Multi-agent Based Semantic E-government Web Service Architecture Using Extended WSDL

The paramount of e-government is seamless integration of services across organizational boundaries. This requires interoperation of heterogeneous services for which web services are being used currently. However there are several limitations of web services. Due to the absence of some important characteristics web services cannot overcome these limitations. Therefore to eliminate them the paper presents an architecture that augments web services with multi-agent technology and uses OWLS (Web Ontology Language for Services) for semantic description, thus paving the path for seamless integration of government services. The paper also discusses the implementation of the proposed architecture and a critical evaluation which resulted in the identification of reasons behind slow adoption of semantic web services. In addition to this a solution is proposed that is believed to increase the adoption rate due to its simplicity. The solution recommends extending WSDL (Web Service Description Language) to represent semantic information
