However, state of the art works offer only a limited support for these concerns especially when it comes to the composition of multiple non-functional concerns with composite web services. In this paper, we focus on the composition of non-functional actions (NFA) with composite web services whose composition logic is made explicit using languages such as BPMN2 or WS-BPEL (gray box view). In contrast to the black box view where only the interface of the service is visible the gray box view reveals additional information on control flow, data flow, composed services, etc. NFAs can also be composite and constitute complex processes such as secure conversations or transactions which have to be integrated with composite web services. Additionally, the execution order of multiple superimposing NFA has to be declared. In our approach we introduce a model-driven approach for the integrated specification and realization of the different types of NFC composition (NFAs with composite services, execution order of superimposing NFAs and composite NFAs) as well as a set of editors and code generators supporting this approach.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134027926","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}

Meinel","doi":"10.1109/ICWS.2011.80","DOIUrl":"https://doi.org/10.1109/ICWS.2011.80","url":null,"abstract":"Identity federation denotes a concept for the controlled sharing of user authentication and user attributes between independent trust domains. Using WS-Federation, service providers and identity providers can set up a Circle of Trust, a so called federation, in which each member is willing to trust on assertions made by another partner. However, if a member has to rely on information received from a foreign source, the need for assurance that the information is correct is a natural requirement prior to using it. Identity assurance frameworks exist that can be used to assess the trustworthiness of identity providers. The result of this assessment is a level of trust, that can be assigned to an identity provider. However, existing approaches for evaluating identity assurance do not allow to define trust levels for individual attributes. In our trust model, we consider both: (a) trust in an identity provider as the issuer of assertions and (b) trust in single attributes that an identity provider manages. In this paper, we show how our approach that we implemented in a logic-based framework can be used in web service scenarios to provide trust information on the level of identity attributes, especially about the verification process, and to match trust requirements of attributes during request processing.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116875914","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}

User's requests consist of functional and nonfunctional requirements. During service composition, services that fulfill the functional requirements are located at the discovery stage. Abstract nonfunctional requirements should be identified mainly before the selection stage for service execution. Our research was motivated by the identification of abstract nonfunctional properties (NFPs) for a seamless ASC and proposes transformation from the abstract NFPs to intermediate-level NFPs based on the model of three levels of abstractness of NFPs. To solve the vagueness of the abstractness, we adapt approaches based not only on ontology but also on term similarity. The transformation between the intermediate and the concrete levels is carried out by a deterministic algorithm based on mapping of domain ontology. To evaluate the effectiveness of term similarity metrics for nonterminal terms, vector-based and large corpus-based approaches were investigated. The transformation performance based on precision over our test data set and ontology was evaluated.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"298 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123192621","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}

Along with the Service Oriented Architecture, companies can wrap their technological product as a service, to collaborate with others. Facing the ever-escalating global competition, such collaboration is crucial. The viability of this paradigm highly depends on the compliance and therefore the trustworthiness of all collaborators. However, it is challenging to achieve trustworthiness in such a dynamic cross-domain environment, as each participator may deceit for individual benefits. As a solution, we have proposed to enforce strong accountability to enhance the trustworthiness. With this accountability, incompliance can always be determined in a provable and undeniable way. In this paper, we extend our work by proposing a novel modeling of the collaborative business process. Based on this modeling, we thoroughly analyze the evidence and proving procedure needed for different types of compliance, and evaluate the extent to which those compliance can be indeed proved. We have implemented a demonstrative system to show its effectiveness in real practice.","PeriodicalId":118512,"journal":{"name":"2011 IEEE International Conference on Web Services","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123471033","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}
