In this paper, an approach for reorganizing Web sites based on user access patterns is proposed. The approach consists of three steps: preprocessing, page classification, and site reorganization. In preprocessing, pages on a Web site are processed to create an internal representation of the site, and page access information of its users is extracted from(More)
Various clustering algorithms have been developed to group data into clusters in diverse domains. However, these clustering algorithms work effectively either on pure numeric data or on pure categorical data, most of them perform poorly on mixed categorical and numeric data types. In this paper, a new two-step clustering method is presented to find clusters(More)
In this paper, we propose to mine Web usage data on client side, or personal Web usage mining, as a complement to the server side Web usage mining. By mining client side Web usage data, more complete knowledge about Web usage can be obtained. A framework for personal Web usage mining is proposed. Some related issues and applications of personal Web usage(More)
To prevent decoding failure of MPEG-based applications caused by error propagation, the present study modifies multi-streaming mechanism of SCTP protocol and proposes a transmission control approach which can adjust transmission policy dynamically according to the quality of service requirement of individual frame. The simulation results confirmed that the(More)
In order to run a successful website, it is significantly crucial for website owners to understand users' intentions and desires. By capturing these information, they can provide better service and enhance marketing strategy to achieve this goal. Web usage mining (WUM) is an application that can help people to explore the useful patterns of users' browsing(More)
In order to achieve seamless handover for real-time applications in the IP Multimedia Subsystem (IMS) of the next-generation network, a multiprotocol combined handover mechanism is proposed in this paper. We combine SIP (Session Initiation Protocol), FMIP (Fast Mobile IPv6 Protocol) and MIH (Media Independent Handover) protocols by cross-layer design and(More)
