Relying on XML and Web Service technologies under Service-Oriented Architecture (SOA) environments, this paper presents a model for continuous auditing on internal control, referred to as Collaborative Continuous Auditing Model (CCAM). By the wrapping of data transformation components with Enterprise Resource Planning databases, software venders can provide schema-matching services for the client companies of audit firms to transform data for real-time business transaction validation. Our study identifies the main components of CCAM and describes the collaborative continuous auditing processes among audit firms, client companies, schema-matching service providers, and service registries. This paper concludes with suggestions for future research.

This research introduces personalized recommendation service into library services. Using the borrowing record of the library as basis, the association rules of data mining technique are used to look for book association by focusing on reader's borrowing mode, personal interest and trait in order to simplify the complexity of recommendation structure. The Bayesian network concept is used to build up a personalized book recommender system in order to generate different book recommendations, ranking from high to low, to help reader to locate book information most suitable to his requirement. Meanwhile we use user satisfaction questionnaire to understand the accuracy of recommended books and further to feedback information in order to help the post learning of Bayesian network parameter. This is for the perfection of the overall structure of recommender system so that readers could make use of the resource of the library more effectively and the value of the library system could be further improved.

Multi-Protocol Label Switching (MPLS) is in the process of standardization by the Internet Engineering Task Force (IETF). It is regarded as a technology for traffic engineering and QoS in IP-networks. We proposed an IETF Policy-based Network Management Framework and policies with MPLS specific classes. It uses a three-level policy architecture, which includes managing on device, network, and service level using policies for supporting Inter-serve and Diff-serve based end-to-end QoS in the Internet. A prototyping of policy-based management system for MPLS Traffic Engineering is operating on MPLS network elements. Several experiments illustrate the efficiency and feasibility in this architecture. The results show it can reduce the time of the setup of MPLS traffic engineering tunnel over hops and MPLS traffic engineering tunnel deletion. The proposed integrated policy based management architecture will allow network service providers to offer both quantitative and qualitative services while optimizing the use of underlying network resources.
