“…Also, researchers have begun to develop various solutions (Uren et al 2006;Mrissa et al 2007;Di Lorenzo et al 2009), albeit with limited scope, to produce context information for interpreting the data provided by Web services. Therefore, we expect over time such context information will become increasingly available in the published Web services so that our proposed approach can be used more easily and smoothly.…”

Web services composition is often hampered by various types of data misinterpretation problems. In this paper, we present a comprehensive classification of the data misinterpretation problems. To address them, we develop an approach to automatic detection and reconciliation of data interpretation conflicts in Web services composition. The approach uses a lightweight ontology augmented with modifiers, contexts, and atomic conversions between the contexts, implemented using XPath functions and external services. The WSDL descriptions of Web services are annotated to establish correspondences to the ontology and contexts. Given the naive Business Process Execution Language (BPEL) specification of the desired Web services composition with possible data interpretation conflicts, the reconciliation approach can automatically detect the conflicts and produce the corresponding mediated BPEL by incorporating appropriate conversions into the composition. Finally, we develop a prototype to validate and evaluate the reconciliation approach.

“…To support the composition of data sources in the Internet, especially in the recent Web 2.0 phenomenon, many data composition tools have been developed [14], [15]. However, existing techniques mainly focus on selecting data sources based on data structures and on dealing with syntax and semantics of the data, but neglecting data terms.…”

Abstract-Currently, rich and diverse data types have been increasingly provided using the Data-as-a-Service (DaaS) model, a form of cloud computing services. However, data offered by DaaS are constrained by several data concerns that, if not automatically being reasoned properly, will lead to a wrong way of using them. In this paper, we support the assumption that data concerns should be explicitly modeled and specified in data contracts to support concern-aware data selection and utilization. Instead of relying on a specific definition of data contracts, we analyze contemporary data contracts and we present an abstract model for data contracts. Based on the abstract model, we propose several techniques for evaluating data contracts that can be integrated into data service selection and composition frameworks. We also illustrate our approach with some realworld scenarios.

“…With this annotation, we are describing the message in terms of an OWL class in an existing ontological model. This message is set as an output of the "pubCityState" operation in a portType (lines [18][19][20][21][22] and included in a portlet type binding (lines [23][24][25][26][27][28][29][30][31][32][33][34][35]. The "pubCityState" operation corresponds to broadcasting the city and state information to PropertyBroker.…”

“…As a number of research works suggest [32], [28], [33], [34], most tools provide limited search and discovery for mashup components. Users still need to know how to write code (e.g., JavaScript or XML/HTML) and link the components using technical concepts derived from programming.…”

Abstract-The need for integration of all types of client and server applications that were not initially designed to interoperate is gaining popularity. One of the reasons for this popularity is the capability to quickly reconfigure a composite application for a task at hand, both by changing the set of components and the way they are interconnected. Service-Oriented Architecture (SOA) has recently become a popular platform in the IT industry for building such composite applications with the integrated components being provided as Web services. A key limitation of solely Web-service-based integration is that it requires extra programming efforts when integrating non-Web service components, which is not cost-effective. Moreover, with the emergence of new standards, such as Open Service Gateway Initiative (OSGi), the components used in composite applications have grown to include more than just Web services. Our work enables progressive composition of non-Web-service-based components such as portlets, Web applications, native widgets, legacy systems, and Java Beans. Further, we proposed a novel application of semantic annotation together with the standard semantic Web matching algorithm for finding sets of functionally equivalent components out of a large set of available non-Web-service-based components. Once such a set is identified, the user can drag and drop the most suitable component into an Eclipse-based composition canvas. After a set of components has been selected in such a way, they can be connected by data-flow arcs, thus forming an integrated, composite application without any low-level programming and integration efforts. We implemented and conducted extensive experimental study on the above progressive composition framework on IBM's Lotus Expeditor, an extension of an SOA platform called the Eclipse Rich Client Platform (RCP) that complies with the OSGi standard.
