However, current solutions have limitations of inefficiency and including redundant Web services in the results. In this paper, we proposed a redundant-free Web services composition search based on a two phase algorithm. In the forward phase, the candidate composition will be found efficiently by searching the link Index. In the backward phase, redundant-free Web services compositions are generated from the candidate composition by using the concepts of tokens. Experimental results demonstrate the performance benefits of our proposed techniques compared to state-of-the-art composition approaches.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117284934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper we focus on modeling and discovery of generic data providing services (DPS), with the goal of making data providing services available for interactions with service requesters in contexts such as service composition and mediation. In our model RDF Views are used to represent the content provided by the DPS. A characterization of match between description of DPS as RDF Views and the OWL-S service request is specified, based on which we developed a flexible matchmaking algorithm for discovery of data providing services. Finally, we propose a realization of the DPS using a SOAP version of the SPARQL protocol and a dynamic configuration interface allowing easy interactions of service requesters with data providing services.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125815027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the reasons for this is the inability in most current workflow languages to support large and complex applications that require workflow integration and data sharing between workflows. In this paper, this issue is addressed by the introduction of the two approaches used in the Service Workflow Language (SWFL): the Procedure-Oriented approach, and the Objected-Oriented approach, for workflow integration. The data sharing and related synchronization issues that are associated with these workflow integration approaches are also discussed.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122956033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This, in turn, has led to a large number of process variants derived from the same model, but differing in structure due to the applied changes. Generally, such process variants are expensive to configure and difficult to maintain. This paper provides a sophisticated approach which fosters learning from past process changes and allows for mining process variants. As a result we obtain a generic process model for which the average distance between this model and the respective process variants becomes minimal. By adopting this generic model in the PAIS, need for future process configuration and adaptation decreases. We have validated the proposed mining method and implemented it in a powerful proof-of-concept prototype.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114179004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our notion of WSC is very general: the composition semantics includes background knowledge and we use the most general notion of matching, partial matches, where several web services can cooperate, each covering only a part of a requirement. Unsurprisingly, automatic composition in this setting is very hard. We identify a special case with simpler semantics, which covers many relevant scenarios. We develop a composition tool for this special case. Our goal is to achieve scalability: we overcome large search spaces by guiding the search using heuristic techniques. The computed solutions are optimal up to a constant factor. We test our approach on a simple, yet powerful real world use-case; the initial results attest the potential of the approach.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116586935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But most of these studies and standards focus on the access control policies for individual web services and do not consider the access issues in composed services. Consider a simple service chain where service s1 accesses s2, and s2, in turn, accesses service s3. The information returned from s3 to s2 may be used to compute some results that are further returned to s1. The current web service security framework does not provide any mechanisms to control such an information flow, and hence, sensitive information may be leaked to s1 without the consensus of s3. In this paper, we propose an enhanced security model to facilitate the control of information flow through service chains. It extends the basic security models by introducing the concepts of delegation and pass-on. Based on these concepts, new certificates, certificate chain, delegation and pass-on policies, and how they are used to control the information flow are discussed.","PeriodicalId":275591,"journal":{"name":"2008 IEEE International Conference on Web Services","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123669074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
