It is sometimes indispensable to get end users involved. However, there are some requirements: 1) Allow users to express their desired goals incrementally. 2) Allow users to specify key trajectory constraints. 3) Provide intelligent assistance to users in the composition. Intuitively we propose a user-steering explorative service composition approach that can support extended goals. It gives users more control and facilitates incremental development by suggesting candidate paths. During the generation of candidate paths, we use heuristics to find better plan paths, then guide users to gradually progress towards the goal. The proposed approach is verified in a typical bioinformatics scenario. The preliminary experiment results show that the approach can improve the efficiency and timelyness of service composition.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115007877","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}

Due to the dynamic behaviors and fluctuations of resources in equipment grid, some previously accepted advance reservations are unable to be fulfilled. In this paper, we present a predictive admission control algorithm to decide whether new advance reservation requests can be accepted according to their QoS requirements and prediction of future resource utilization. Historical data are used in this algorithm to predict future status of resources. Experiments demonstrate that our algorithm can reduce the number of accepted advance reservations that fail to be fulfilled and keep the resource utilization ratio at an acceptable level.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"45 38","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120836368","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}

For the purpose of capacity planning and resource provisioning, it is important to understand these services' demand for system resources, e.g., CPU. In this paper, we propose a black-box method for estimating CPU demand of service requests based on linear regression between the observed request throughput and resource utilization level. A key advantage of our method is that its input data (i.e., request-processing throughput and resource utilization) can be easily obtained without intrusive software instrumentation. Moreover, we observe that, in an SOA environment, the service composition relationship (i.e., how low-level atomic services are connected into a composite service) is either known in advance or can be discovered through various means. We leverage this composition relationship to further improve the quality of CPU demand estimation. By analyzing the dependency between a composite service and its constituent low-level atomic services using linear algebra, our method can eliminate the collinear problem introduced by the service composition relationship. Moreover, our method can further reduce the number of unknown variables in the linear regression problem, and hence reduce the time duration needed to collect input data. In a dynamic SOA environment, this translates into faster response to changing workloads and more accurate estimation. We demonstrate these advantages of our method over a baseline method through extensive evaluation.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120960070","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}

Frameworks implementing the model-view-controller architectural pattern standardize the development process to a great extent, while business layer components may consist of consumers of existing Web services. On this line of thought a Web application can be seen as a composition of Web services around a user interface flow. In this paper, an approach for the application of model-driven techniques for the automation of the development of such a Web application is presented. Specifically, we present a methodology for the modeling of the application using UML state transition and class diagrams and the generation of the appropriate source code and configuration files. The appropriate UML profiles to assist the service design are defined and the final transformation is performed exploiting model parsing tools.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124833243","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 as much, a registry for inter-organizational systems should cover all three levels and maintain the dependencies between them. In this paper we set up on well accepted approaches on the different levels, i.e. (1) the e3value ontology, (2) the UN/CEFACT modeling methodology (UMM), and (3) the business process execution language (BPEL).

Service-oriented architecture (SOA) has been touted in recent years due its promise of fostering reuse.

In this paper,we present an approach that extracts the domain knowledge and service abstractions from design diagrams of existing software solutions and represents it in a form that can be reused in new projects. We have implemented our approach and preliminary results indicate that both domain knowledge and service abstraction thus extracted can promote reuse of software assets to a large extent.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128119586","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 fact, existing development support tools do not provide any practical mean to assess Web services robustness in the presence of erroneous inputs. Previous works proposed that Web services robustness testing should be based on a set of robustness tests (i.e., invalid Web services call parameters) that are applied in order to discover both programming and design errors. Web services can be classified based on the failure modes observed. In this paper we present and discuss the architecture and use of an on-line tool that provides an easy interface for Web services robustness testing. This tool is publicly available and can be used by both web services providers (to assess the robustness of their Web services code) and consumers (to select the services that best fit their requirements). The tool is demonstrated by testing several Web services available in the Internet.","PeriodicalId":399213,"journal":{"name":"2008 IEEE International Conference on Services Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125708306","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}
