Discovering Semantic Web Services with Process Specifications

چکیده
Service discovery is one of the crucial issues for service-oriented architectural model. Recently the trend is towards semantic discovery by which semantic descriptions are the basis for service matchmaking instead of simple search based on service attributes. OWL-S is a widely adopted semantic specification for Web Services which comprises three profiles. Among those, process model is the profile that describes dynamic behaviour of Web Services in terms of functional aspects and process flows, and is generally aimed for service enactment, composition, and monitoring. This paper presents a new approach to use OWL-S process model for service discovery purpose. A Web Service can have its internal process described as an OWL-S process model specification, and a service consumer can query for a Web Service with a particular process detail. Matchmaking will be based on flexible ontological matching and evaluation of constraints on the functional behaviour and process flow of the Web Service. The architecture for process-based discovery is also

Light-Weight Semantic Service Annotations Through Tagging
Discovering and composing services is a core functionality of a service-oriented software system. Semantic web services promise to support and (partially) automate these tasks. But creating semantic service specifications is a difficult, time-consuming, and error prone task which is typically performed by service engineers. In this paper, we present a community-based approach to the creation of...
متن کاملAutomatic Web Service Selection Using Ontology and Quality of Service
We develop a framework for integrating bioinformatics tools based on Semantic Web technology. Specifications of abstract workflows are expressed in Business Process Execution Language for Web Services (BPEL4WS). A problem-solving agent is responsible for automatic analyzing and discovering the web services in the abstract workflows, and selecting among them in order to optimize the quality of s...

SQUID-WS is a system utilizing semantic annotation of web services to increase the accuracy of web service discovery. Service providers and requestors specify characteristics of web service operations using a common ontology (OWL ontologies are used), and a matching engine is used to match specifications. An inference engine is used to determine whether service advertisements meet additional co...

In this paper we will show how the ontology of the Process Specification Language can be used as an upper-level process ontology that serves as the semantic foundation for the DAML-S ontology for web services. 1 Semantics for Web Services To achieve the vision of the Semantic Web, software agents will need a computerinterpretable description of the services they offer and the information that t...
متن کاملMatchmaking for Semantic Web Services with Constraints on Process Models
-. Service discovery is part of the service-oriented architectural model and supported by any of the realising technologies including Web Services. This paper presents an agent-based system for discovering semantic Web Services whose behaviour is described by OWL-S process model. Rules can be set to constrain service processes, and criteria for considering matching between a service process and...
