A discovery process identifies the suitable candidate services for a composition. A subsequent selection process chooses the optimal candidate for each task. The selection process can consider - if supported - different quality-of-service (QoS) categories of the individual services to optimize the quality of the whole composition. The result is a quality-optimized assignment of candidates to each task. This paper discusses how already identified candidates, which a selection process originally has separated out, can improve a composition w.r.t. particular QoS categories. To realize this improvement, redundant arrangements involve the alternative candidates in order to supplement the originally assigned service. We formed these redundant arrangements on the basis of our previously introduced compositions patterns. The contribution of this paper is a model which allows aggregating the resulting QoS of the composition when these arrangements are applied.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115657927","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 basic step toward this interoperation is that users or services can discover the services according to their requirements. In this paper we present a practical application on semantic Web and Web services concepts where a flexible and automatic matching procedure in e-learning is shown. We illustrate how the requirements, Web services and domain knowledge are described in machine-understandable form to support the automatic and flexible discovery of Web services. Then a matchmaking algorithm based on the semantic information is proposed. Finally the design and implementation of a prototype of Web service automatic discovery is described.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114349142","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 previous works, we propose an approach, using the aspect oriented programming (AOP) paradigm, to increase the adaptability of Web services. This approach suffers from some deficiencies as dependency for both the programming language (Java) and the SOAP engine (AXIS). In this paper, we propose to increase the adaptability of Web services by using the main AOP agreed semantics - advices, pointcuts and joinpoint - to change original Web service behavior. In the new approach we consider that advices are themselves a Web service. Moreover, we propose to use an XML language for describe pointcuts, joinpoint and to referencing advices. The invocation of advices (Web services) is accomplished by an XQuery engine to assure SOAP engine independency and advices are implemented as Web services to promote programming language independency.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117312888","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}

A system fitting all needs would be huge and complex, too hard to use and evolve, but on the other extreme, developing many specialized process environments for each need would lead to a situation where many independent and incompatible process islands prohibit a consistent and global process management of a company. This paper proposes an approach where a process environment can be tailored to specific needs, most notably for Web service orchestration. We illustrate the approach by an example and justify it by the validations we have made.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129610964","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}

Service based workflow, which integrates and manages Web services distributed in the Internet, has grown to be one of the hottest topics in the workflow research areas. The high dynamic and heterogeneous nature of the Internet brings uncontrolled factors while integrating and invoking outside Web services in workflow. So the failed execution in service based workflow system occurs more often than that in the traditional workflow system. Thus transaction management is a key to ensure the successful execution of service based workflow. Based on a detailed analysis of the characteristics of service based workflow, it proposed a transaction management framework to maintain the integrity of workflow transactions. Using this framework, a workflow management system can improve its ability in processing transaction issues while managing service based workflow.","PeriodicalId":433802,"journal":{"name":"International Conference on Next Generation Web Services Practices (NWeSP'05)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128476040","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}
