Each web service may exploit its own XML format for data representation which causes problems with their integration and evolution. Manual integration and management of evolution of the XML formats may be very hard. In this paper, we present a novel method which exploits a conceptual diagram. We introduce an algorithm which helps a domain expert to map the XML formats to the conceptual diagram. It measures similarities between the XML formats and the diagram and adjusts them on the base of the input from the expert. The result is a precise mapping. The diagram then integrates the XML formats and facilitates their evolution - a change can be made only once in the diagram and propagated to the XML formats.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116870976","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}

However, most existing monitoring technologies only track patterns related to the execution of an individual process. As a result, the possible inconsistency failure caused by implicit interactions among concurrent process instances cannot be detected. To address this issue, this paper proposes an approach to specify the behavior properties related to shared resources for web service compositions and verify their consistency with the aid of a parametric stateful aspect extension to WS-BPEL. Parameters are introduced in pattern specification, which allows monitoring not only events but also their values bound to the parameters at runtime to keep track of data flow among concurrent process instances. An efficient implementation is also provided to reduce the runtime overhead of monitoring and event observation. Our experiments show that the proposed approach is promising.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124091808","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}

RFC is the standard SAP interface for communication between SAP systems. SOAP is widely used in web service solutions for its nature cross-platform characteristic. It uses platform independent eXtensible Markup Language (XML) but it introduces more latency tags to represent the data. Thus, SOAP might need more memory and transferring time. This paper studies and compares their performance characteristic with introducing an evaluation model and then evaluates them for different use cases.

There is an increasing interest on its application to real-time communication web services. Based on a case study of CSTA services, we found that communication services exhibit a combination of complex message exchange and stateful behavior patterns, including multi-states, two-way interaction, event-driven, multi-resources, multi-responses and session management, that need to be modeled properly within the framework of REST. To address these challenges, we propose three REST design patterns: session, event subscription and relationship using REST composition. This approach leads to a systematic one-to-one transformation from CSTA to REST. We hope such a study on a concrete use case can contribute to a better understanding of REST and lead to a seamless convergence of communication services with the infrastructure of the Web.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121791017","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}

The devised model is an application of the generic model about tasks allocation for agents, which is presented in [13]. We consider that a collaboration between Web services captures a possible interaction for achieving a specific task. We consider such collaboration as a game in which several Web services compete to win a task by bidding a cost for achieving it. The game winner is the Web service which has the minimal trust-based cost, which is the product of the cost and the inverse of the trust value of the bidding Web service. Initial trust values are computed based on the distance between the actual and the announced quality attribute values of a Web service. These values are computed during a collaboration evaluation period. They are updated after each game round based on a bayesian model. We show in this paper how the use of trust allows a safer collaboration between Web services with respect to collaborations where there is no consideration of the trust as a criteria for allocating tasks.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121853","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}

We exploit techniques from Software Product Line (SPL) domain, particularly feature modeling techniques, to design our framework. Feature modeling allows to abstract variability in consumers’ requirements to simplify customization processes, while automated analysis on feature models helps to validate customizations. The use of feature models at runtime enables dynamic deployment of a business process as a result of a service customization. We propose the use of feature models as service description artifacts to facilitate service customizations. The framework builds on a Model-Driven Development (MDD) approach to automate large parts of its operation.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133515825","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}

These applications are built by the coordination between set of Web services. Therefore, checking the compatibility between two services to guarantee that they can interact correctly is an important issue. In case of service update or replacement, there is a need for checking the replaceability to ensure that the new service is compatible with all the services which were compatible with the replaced one. These two type of checking are based on the services descriptions. Enriching services descriptions by including their behaviours is becoming more and more important. This behaviour can be described by business protocols representing the possible sequences of message exchanges. Since a lot of Web services use access control policies to restrict the access to authorized consumers, these policies should be a part of the service description. Checking compatibility and replaceability between Web services by analyzing their business protocols after assigning the access control policies is the main contribution of this work. Access control policies will be presented using ontology.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129892118","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}

To help end-users obtain their desired services, context-aware systems provide a promising way to automatically search and recommend services using a user’s context. However, existing context-aware techniques have limited support for dynamic adaption to newly added context types (e.g., location, time and activity). Due to the diversity of user’s environment, the available context types may change over time. It is challenging to anticipate a complete set of context types while we design a context aware system. In this paper, we propose a context modeling approach which can dynamically handle various context types and values. More specifically, we use ontologies to enhance the meaning of a user’s context values and automatically indentify the relations among different context values. Based on the relations among context values, we capture the potential services which the user might need. A case study is conducted to evaluate the effectiveness of our approach. The results show that our approach can use contexts to find users’ needs and recommend their desired services with high precision and recall.","PeriodicalId":170573,"journal":{"name":"2010 IEEE International Conference on Web Services","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128351728","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}
