A Method for Semantic Web Service Selection Based on QoS Ontology

Abstract

<p>In order to select the proper one from the web service candidate sets which are provided by semantic matching, a method for web service selection with QoS (quality of service) constraints is proposed. In this paper, firstly, the Four-Level Matching Model for Semantic Web Service based on QoS Ontology, which includes Application Domain Matching, Description Matching of Service, Function Matching of Service and QoS Matching, is presented, then, the QoS ontology for web service is constructed and the QoS description information with the QoS concept in OWL-S (Web Ontology Language for Services) model is extended, thirdly, the extensible OWL-SQ model for service description with service semantic and QoS description is presented, and it is QoS supporting and constraining. Then based on decision theory and normalized algorithm, the dimensionless method of QoS properties for un-numerical value type and numerical value type in OWL-SQ model is proposed. Finally, the algorithm for constructing matching matrix of QoS and the service selection method are presented, to evaluate and select optimization candidate web service comprehensively. Test result shows that the efficiency and accuracy of service selection are improved with the service selection method based on OWL-SQ model.</p&gt

A Framework for Managing Services in a Virtual Community Context

“…QoS is very important in order to select the most suitable service from a set of candidate ones [17]. Accordingly, a matching between QoS attributes is required to unify the properties used for each type of service.…”

“… Web services quality modelling approach proposed in (OASIS, 2012) stands for the approaches based on the activity-based separation of quality concerns.  Quality of services modelling approach proposed in (Bianchini et al, 2004) stands for the approaches based on the service ontology (Guo, 2011;Dobson et al, 2005). The choice of representatives also demonstrates the scheme for classifi cation of QoS models.…”

Semantic-based Web services selection for mobile

“…Its function is to implement extensible automatic or semi-automatic service discovery and composition in the dynamic, open and heterogeneous network environment with the support of abundant semantics [10].…”

“…They use OWL-S ontology for semantic Web services, but unfortunately OWL-S does not contain the ideas for QoS and context. Guangjun Guo and Fei Yu et al at [10] introduced the finest matching matrix for estimating the greatest candidate services. Firstly, the Four-Level Matching Model based on QoS Ontology was specified then Web services' QoS ontology with QoS notion in OWL-S model is presented.…”
