Aimed at the drawbacks of traditional similarity measurement methods, we put forward an improved similarity measurement method. The entropy-based collaborative filtering algorithm contributes to solving the cold-start problem and discovering users' hidden interests. Using the practical data obtained from Movielens Website and MAE metrics for accuracy measure, three different collaborative filtering recommendation algorithms are compared through experiments. The results show that the entropy-based algorithm provides better recommendation quality than user-based algorithm and achieves recommendation accuracy comparable to the item-based algorithm. The experimental solution, the advantages of the entropy-based algorithm and future work are discussed in detail.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130681342","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}

Therefore, this paper proposes a dataflow driven dynamic service composition architecture aiming at astronomy applications, to simplify the requirements for users to compose a service. The architecture utilizes Dataflow Driven conception to discover an Original Topology Graph, which includes the final composite service with the shortest length and good parallel structure, and uses a Converse Composition algorithm to ascertain the final result quickly. This architecture is applied in the PMGrid prototype for astronomy data processing, and the experiment results show the architecture satisfies the parallelism and asynchrony in distributed system, avoids manual errors, increases the service configuring efficiency, provides the composite service with better structure to increase the executing parallelism, and finally improve the scientific discovery.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"993 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123097548","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 Web service may be invoked by other Web services or users and the way for interacting with users or other services should be different. When interacting with a user, it is necessary to provide a graphical user interface (GUI) to obtain the input information. Users may access the Web Service from different devices. To manually develop various user interfaces for Web services adds additional burdens to the service designers. In this paper, an adaptive user interface generation framework is presented. The framework takes the WSDL interface specification together with some additional but optional interface design related information for adaptive GUI generation.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121202281","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 search of these private documents for different organizational users with role- based access control is a challenging task. In this paper, we present a novel content-based XML-annotated secure-index search mechanism that provides an effective search and retrieval of private documents with document-level security. The search mechanism includes a document analysis framework for text analysis and annotation, a search indexer to build and incorporate document access control information directly into a search index, an XML-based search engine, and a compound query generation technique to join user role and organization information into search query. Our experiments on a pilot electronic contract system demonstrate that, by incorporating document access information directly into the search index and combining user information in the search query, search and retrieval of private contract documents can be achieved very effectively and securely with high performance.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125312150","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}

It is critical that the provider clearly understands and properly implements its complete service obligations to the client. The BlueMoon project in IBM develops a novel approach to service obligations management in the context of IT outsourcing. BlueMoon conceptualizes different kinds of service obligations through a formal obligations model. It provides an overarching obligations configurator tool for gathering and validating obligation requirements throughout the outsourcing lifecycle. It further facilitates the implementation of service obligations by automatically binding them to the IT architecture planning and provisioning process and to their uses in various service documents. Work is under way to monitor service delivery operations and verify obligations compliance. Addressing a key challenge in IT outsourcing, bluemoon promises to significantly improve the client's satisfaction, the health of the outsourcing account, and the provider's bottom line.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131930841","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 objectives of knowledge harvesting are to not only succeed in eliciting experts' knowledge but also develop effective training and learning designs as well as their evaluation. However, the successful implementation of such program remains a key challenge. Management needs to develop an understanding of the factors that have significant associations to a successful implementation of such program. Prior research has linked the factors of employees' engagement to their performance level. The purpose of this study is to identify and examine the factors that have significant impacts on the successfulness of knowledge harvesting. This study investigates the relationship between these factors and personal engagement of experts and novices in knowledge harvesting process.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114690952","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}

Different types of web requests are considered in this paper: best-effort requests and multi-class QoS-demanding requests. Each request is associated with a certain amount of revenue. The system earns associated revenue when completing a best effort request, while the revenue earned for serving a QoS-demanding request depends on the degree of satisfaction. The complete server pool is divided into two clusters of servers, each dedicated to serving one type of request. The total profits accrued when serving these requests are mathematically modelled in this paper. The optimisation equations for the pool partitioning have also been constructed so that the maximum profit can be achieved. An optimal server switching policy is also developed. The server switching policy is optimal in the sense that the maximum profit can be maintained by switching servers from one partition to the other. Costs involved in server switching are factored into the switching model. Supportive experimentation based on simulation have been conducted and the results verify the effectiveness of the pool partitioning policy and the server switching policy developed in this paper.","PeriodicalId":184487,"journal":{"name":"IEEE International Conference on e-Business Engineering (ICEBE'07)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125201778","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}
