Goal models depict users’ desires in terms of goals, namely, why-to-do; BPEL provides means to describe web service composition using WS-BPEL2.0, namely, how-to-do. However, there exists a gap between changes of individualized requirements and web service composition in the meet-in-the-middle pattern. So, in the paper we proposed an aspect-oriented approach to support web service composition evolution triggered by requirements evolution. The approach elevates the abstraction level of evolution modeling for web service composition, namely, from business process level to strategic goal level. The result is to make business level person capable of taking part in evolution modeling at requirements phase.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122137497","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 online auction system based on the campus network provides a trading platform for university students, and does not deal with the trading process. So the online auction system must increase its quality of service to attract students. In this paper, we present a scheme for the online auction system using the unified modeling language (UML) technique. We adopt the two steps to design the scheme, and the design scheme of the system is made up of use case diagrams, activity diagrams, class diagrams, sequence diagrams, deployment diagrams. In addition, the scheme can provide certain reference values for constructing the campus electronic commerce and realizing the digital campus.","PeriodicalId":375180,"journal":{"name":"2009 Second Pacific-Asia Conference on Web Mining and Web-based Application","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128629551","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 perform the semantic expansion based on ontology, semantic expansion algorithm and semantic expansion functions based on ontology are proposed and used in the model.
