SWSMS: A Semantic Web Service Management System for Data Sharing in Collaborative Environments

In today´s collaborative environments such as bioinformatics and healthcare, the access to an increasing number of data sources has been made in the form of Data-Providing Web Services. Current approaches to composing Web services are not suitable for this special class of Web services as they do not take into consideration the semantic relationship that holds between input and output sets of a Web service. In this paper, we present our Web Service Management System (WSMS) that is used to exchange data through Data-Providing Web Services. In our system we employ a novel approach for automatically composing data-providing services by making usage of the mature work that has been done in the conventional data integration and mediation systems. Specifically, we model data-providing services as RDF parameterized views over mediated ontologies. We devise an algorithm for composing services based on conventional query rewriting techniques. Our WSMS is very useful in domains such as bioinformatics and healthcare where web services are used extensively to exchange data.
