In this paper, a service agent model is proposed, which integrates the Web service and software agent technologies into a cohesive entity. Based on the service agent model, a distributed agent coalition algorithm for autonomic Web service composition named as DACA is proposed. DACA is fully distributed, which is based on the distributed decision making of the autonomous service agents and addresses the distributed nature of Web service composition. The simulation experimental results demonstrate that the proposed DACA is effective for its ability to produce high quality solution at a low cost of communications.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117019544","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 contrast to traditional desktop applications, enterprise applications have to consider performance aspects as a result of the distributed application setup.

We present implementation details about our abstract application layer for consumption of enterprise services providing dynamic load and transparent caching methods. Dynamic loading of business object data facilitates comfortable use of enterprise services by clients without expertise on service implementations.We examine various server- and client-side caching strategies and implemented a performance testbed.

In order to reduce the complexity of service composition, various approaches based on semantic technologies and planning techniques have been developed for automatic service composition. However these approaches have focused on composition aspects and have not facilitated users expressing their business demands easily and flexibly. In this paper, we propose a semantic framework that automatically transforms high level task definitions into executable processes. The task language OWL-T is developed for defining complex tasks that capture users’ business requirements. Semantic technologies are utilized to map such task templates into executable processes expressed in the BPEL language. An implemented prototype was developed for illustrating the practical potential of the framework.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131256033","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}

As the amount of data increases, the way engineers define their own experiments, analyze the output and share them is becoming complex to manage. Scientific Workflow Management Systems (WfMS) are being used to orchestrate a sequence of programs, services and resources, defined by scientific workflows. However, current WfMS are focused on the workflow execution and present limitations on the semantic support to design the experiment. These tools lack on semantic descriptions of available resources to design scientific workflow. This paper presents an ontology for deep water oil exploration workflow. This ontology has been used to present some semantic concepts to help defining a workflow to be further executed by a WfMS. We evaluate this semantic support on a real workflow that calculates fatigue on risers in deep water oil platforms. The results reinforce the benefits of semantic support over program chaining in manual workflow design.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123585441","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}

Data mismatch between WSs is often considered as an orthogonal problem that can be solved using XML data model and query languages, e.g., XQuery . We argue that Web services composition and data manipulation should be considered holistically such that further optimization on Web service composition becomes possible. In this work, we define a model, called WS-data model, for composing WSs with focus on their data exchanges. We propose several operators that can be used to compose WSs and manipulate the generated data. Properties of these operators are discussed and an example is given to show how these properties can be utilized to identify a more efficient way for realizing a complex task expressed using a WS-data expression.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122077705","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}

As an alternative, stateless process enactment entails that process state is derived from the state of business objects, which are organized in a domain model. The business objects are referred to in pre- and post-conditions of activities, which determine when the activity is enabled and completed, respectively. Despite the fact that the latter approach has multiple benefits compared with the former, the repeated state (re)calculations deteriorate performance and the formulation of clear conditions is not self-evident if typical domain modeling techniques (e.g. UML or ER) are adopted. In this paper we show that by adopting a specific domain modeling technique, which is based on the notion of existence dependency between the business objects, the performance and comprehensibility issues can proficiently be dealt with. We illustrate the technique using a real-world case from the insurance domain and analyze the emerging duality between process modeling and domain modeling.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114167134","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 order of execution of the tasks in a workflow is commonly controlled by complex scripts, which over time become difficult to maintain and evolve. In this paper, we describe how we have integrated the Kepler scientific workflow platform with the MeDICi Integration Framework, which has been specifically designed to provide a standards-based, lightweight and flexible integration platform. The MeDICi technology provides a scalable, component-based architecture that efficiently handles integration with heterogeneous, distributed software systems. This paper describes the MeDICi Integration Framework and the mechanisms we used to integrate MeDICi components with Kepler workflow actors. We illustrate this solution with a workflow application for an atmospheric sciences application. The resulting solution promotes a strong separation of concerns, simplifying the Kepler workflow description and promoting the creation of a reusable collection of components available for other workflow applications in this domain.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"173 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126781233","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}

They will harness the great potential of the Internet of services. However, today's service exposure tools and service composition tools are too complex to be used by ordinary end-users. They are based on technologies such as REST, WSDL, and SOAP which are hardly understandable by the end-user. In this paper, we propose a widget based service exposure and service creation tool. Our framework creates links between loaded widgets automatically; additional functionalities are thus added automatically to existing widgets as long as the end-user loads other widgets to his personal environment; in the same way as he launches an application on his Windows environment. This mechanism is definitely more intuitive than SOA technologies as it is based on the user interface.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129159735","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}
