“…Contrarily to our approach, these works [15], [16], [17], [18], [29] do not deal with QoS properties to classify Web services. In [19], Chollet et al propose an approach based on FCA to organize the services registry at runtime and to allow the best service selection among heterogeneous and secured services. The services registry is viewed as a formal context where the services are the individuals and the services types, functional, and non-functional characteristics (security characteristics) are properties.…”

“…The obtained lattices are used to check out relevant (that best fit functional requirements) and high QoS Web services. All the works detailed above [15], [16], [17], [18], [29], [19], [30] are based on FCA, and not on RCA. In addition, they do not deal with service composition since they propose to classify and select only individual services.…”

“…This approach is based on Relational Concept Analysis (RCA) [12], a variant of Formal Concept Analysis (FCA) [13], [14]. FCA has been successfully used as a formal framework for service substitution [15], [16], [17], [18], [19]. The approach also integrates a query mechanism that allows users to specify their required QoS and composability levels.…”

Abstract-Building a composite application based on Web services has become a real challenge regarding the large and diverse service space nowadays. Especially when considering the various functional and non-functional capabilities that Web services may afford and users may require.In this paper, we propose an approach for facilitating Web service selection according to user requirements. These requirements specify the needed functionality and expected QoS, as well as the composability between each pair of services. The originality of our approach is embodied in the use of Relational Concept Analysis (RCA), an extension of Formal Concept Analysis (FCA). Using RCA, we classify services by their calculated QoS levels and composability modes. We use a real case study of 901 services to show how to accomplish an efficient selection of services satisfying a specified set of functional and non-functional requirements.

The new paradigm for distributed computing over the Internet is that of Web services (WSs). One of the key ideas of this new paradigm is the ability to create value-added Service-Based Applications (SBAs) by composing pre-existing services. Building SBAs necessitates the discovery and the selection of the most appropriate WSs that fit closely users' functional and non-functional requirements. Due to the large number of WSs that are advertised over public and private registries and the various functional and non-functional capabilities that are required by users, discovery and selection of WSs have become a real challenge nowadays. In this paper, we present a WS composition approach that is built upon both perspectives: intentional and operational. In the intentional perspective, we propose to model users' requirements for SBAs using the MAP formalism and specify the required WSs using an Intentional Service Model (ISM). In the operational perspective, we propose to discover the required WSs by querying the service search engine Service-Finder and select the most appropriate WSs by using many-valued concept lattices. To validate our approach, we use an analytical technique that is the monitoring to verify that the selected WSs assure the required users' non-functional capabilities.

Orchestrating web services aims to compose multiple services into workflows that answer complex user requirements. Web services are software components which are exposed to errors and failures that can occur during web service orchestration execution. Thus, many error-handling and healing approaches have been proposed to guarantee reliable orchestrations. Some of these approaches rely on the identification of relevant service substitutes to heal (by substitution) the defected services. In this paper, we propose an identification process of web service substitutes for healing failed web service orchestrations based on the measurement of similarity between service interfaces. The process reveals both simple and complex (compositions of) substitutes. We validated the approach via a set of experiments conducted on a collection of real web services.
