Knowledge based Web Service Composition
Automated Web service composition remains always one of the most challenging research area due to the continuously growing number of semantic Web services. Several formalization and composition approaches were proposed, but they are not mature and flexible. They assume that each sub-task is an atomic process, hence it cannot be decomposed based on user requirements. Moreover, these techniques and formalizations are not suitable for dynamic environments, does not consider incomplete and ambiguous query for which knowledge might be of great use. The aim of this work is to propose a novel horizontal and vertical composition of Web services based on Fuzzy Constraint Satisfaction Problem (FCSP) with knowledge integration. Knowledge, can be extracted from several sources, i.e. a datawarehouse of abstract workflows containing the best compositional practices in a given domain, ontologies, Web mining, etc. The proposed approach was implemented and applied to randomly generated examples using parameters reflecting the real world. Experimental results showed that the integration of knowledge with the CSP formalization gives remarkably better results in terms of the percentage of solved problems.
Disclaimer/Regarding indexing issue:
We have provided the online access of all issues and papers to the indexing agencies (as given on journal web site). It’s depend on indexing agencies when, how and what manner they can index or not. Hence, we like to inform that on the basis of earlier indexing, we can’t predict the today or future indexing policy of third party (i.e. indexing agencies) as they have right to discontinue any journal at any time without prior information to the journal. So, please neither sends any question nor expects any answer from us on the behalf of third party i.e. indexing agencies.Hence, we will not issue any certificate or letter for indexing issue. Our role is just to provide the online access to them. So we do properly this and one can visit indexing agencies website to get the authentic information. Also: DOI is paid service which provided by a third party. We never mentioned that we go for this for our any journal. However, journal have no objection if author go directly for this paid DOI service.
