Late developments in Web Service discovery approaches mainly focus on the incorporation of the QoS concept in the selection process. In this paper, we present a generalized design and implementation of a QoS enabled Web Service discovery mechanism. We describe a mechanism extending the propositions of [1] in a generalized environment that consists of(More)
Web services have introduced an new era for distributed application development. WS are based on ubiquitously adopted internet standards, therefore supporting interoperability across different platforms. Further establishment of web services in the IT community demands the capability to dynamically respond to different non functional requirements such as(More)
In this paper we discuss the integration of QoS-awa research and personalization algorithms in order to discover effectual Web Services for the case of mobile web users. We present a number of novel ranking algorithms specially designed for mobile web architectures. To validate and evaluate the proposed algorithms we developed a fully working prototype for(More)
In science learning, cognitive concepts that are distinguished for the complexity of their structure and operation can be understood by using successful metaphors. Conventional instruction is ineffective in dealing with misconceptions. We propose a semantic learning interventions management system that utilizes web services technology. The proposed system(More)
