User model is one of the fundamentals to support personalized services. Not only the model has to represent user preferences precisely, but it must reflect the changes of user preferences over time as well. Existing user modeling approaches have several deficiencies such as lack of dynamics and adaptation, so the evolution of these models is much de-pendent on user's explicit feedbacks. Particularly,...
In this paper, a usage model is proposed to simulate users' behaviors realistically in load testing of web applications, and another relevant workload model is proposed to help generate realistic load for load testing. It also demonstrates an eclipse-based load testing tool “Load Testing Automation Framework (LTAF)” which is based on these two models and can perform load testing of web applications...
There are lots of sensitive and confidential data in financial field, such as credit card number, stock number, fund number and so on. Therefore, top level security requirement is always required in financial systems, where a good access control framework is necessary. Traditional role-based access control frameworks lack of control in data access granularity and often slow down the system, even though...
Social networking sites like Flickr , Youtube and Del.icio.us have been rapidly gaining popularity on the Internet, underscoring a transformation of the Web to a participatory medium in which users are actively creating, evaluating and distributing information. With this process, social tagging systems, which allow users to interactively annotate a pool of shared resources using descriptive tags,...
Video annotation is very important for video management, such as video retrieval. Despite continuous efforts in inventing new annotation algorithms, the annotation performance is usually unsatisfactory, and the annotation vocabulary is still limited due to the use of a small scale training set. In this paper, a novel video annotation framework based on the video object is presented, named object-based...
While P2P technology is mainly used in delivering digital content, we believe its characteristics are also suitable to be applied in constructing online electronic marketplace. The features such as low cost, high reliability and performance of P2P network could improve the services of online transaction which currently build on centralized architecture. In this paper, we analyze the desired features...
The VCM (Vector-Correlative Model) is one of the currently popular models for information searching. In this paper, author inducted Fuzzy Sets theory and approach for to construct information searching models, and presented a new VCM, which is called Fuzzy Vector-correlative Model (FVCM). So, its theory structure and user's searching quizzing mode has been dimming improved. We have show with some...
