An extension of the HTN-DL web service model is presented, including rules for web service behavior and compliance validation against customer requests. The intention is to overcome the limitations of HTN-DL and OWL-S in covering business constraints in service selection and also the limitation of preconditions. The proposed approach validates a web service obtained through HTN-DL planning, for compliance...
This paper gives an overview of the work done to develop a task ontology based on the task templates provided by CommonKADS. It discusses how modeling of KBS is done in the CommonKADS and also gives a brief overview of OWL-S which an upper-level ontology for web services. Constructs of OWL-S ontology have been compared with constructs proposed by CommonKADS to see to what extent it can be reused to...
This paper introduces connectionistic concept grid (CCG), which is used for representation and reasoning of engineering knowledge applied for the industrial systems. The paper also presents the Crossword tool which was used for computer aided modelling and execution of CCG. CCG is able to provide semantic descriptions of objects and processes and was developed to overcome limitations of earlier knowledge...
As constraint conditions of Web services, preconditions and effects in OWL-S specification play important role in Web services matchmaking. However, the constraint conditions based Web services matchmaking methods mostly adopt thetas -subsumption, which lacks semantic level support. This paper presents a new semantic matchmaking method of Web services constraint conditions, which integrates rule system...
This paper presents a new approach for automatic Web service composition based on the formalism of Fluent Calculus using semantic Web service descriptions. In our approach, the Web service composition process is viewed as an AI planning problem in the Fluent Calculus formalism. To semantically describe Web services, we have used a Web service domain ontology which is then translated into a Fluent...
In Grid computing different virtual organization provides different types of resources. They also want to put some limitation on the usage of their resources. For this purpose they specify resource usage policies. These policies are different for different type of users and group of people. To submit a job, user first selects resources, required for the execution of the job using semantic matchmaker...
