In this paper, we propose a novel high-dimensional index method, the BM + -tree, to support efficient processing of similarity search queries in high-dimensional spaces. The main idea of the proposed index is to ...
Chapter and Conference Paper
Form-based Web queries are commonly used by Web users for extracting information from the Web. However, some hidden information cannot be retrieved from the Web interface, which results in the limited query an...
Chapter and Conference Paper
Application-centric QoS (AQoS) model is needed for evaluating semantic equivalent Grid Services in an application-oriented service Grid. Previous related researches on QoS mainly are for resource allocation in...
Chapter and Conference Paper
To support very high dimensionality, model-based clustering is an intuitive choice for document clustering. However, the current model-based algorithms are prone to generating the skewed clusters, which influe...
Chapter and Conference Paper
We study cooperative caching technique for supporting data access in ad hoc networks. Two protocols that are based on the notion of zone are proposed. The IXP protocol is push-based in the sense that a mobile ...

Because of the increasing variety of user terminals, there is a great demand for the Web pages adapt to various resolution terminals with good readability. This paper describes an effective approach to display...
Chapter and Conference Paper
We introduce a new surface deformation and modeling method in this paper. Referring to the swept volume generation, the surface is pulled or pushed along a trajectory curve. The key point is the swee** funct...
Chapter and Conference Paper
In sensor networks, multi-join queries are processed by joining sensor data generated at different sensor nodes. Due to the energy constraint, however, sometimes only partial sensor data can be transmitted to ...
Chapter and Conference Paper
Nowadays most web-based learning systems have already utilized advanced technologies like web services and etc., even grid computing to minimize the gap between traditional learning and e-Learning. Meanwhile, ...
Chapter and Conference Paper
An algorithm is presented to construct a C 2-continuous B-spline quaternion curve which interpolates a given sequence of unit quaternions on the rotation group SO(3). We present a method to extend...
Chapter and Conference Paper
With the development of computer and communication technology, access control of the resources in databases has become an issue focused by both consumers and enterprises. Moreover, the new concept of purpose-b...
Chapter and Conference Paper
With the rapid advancement in laser technology, computer vision, and embedded computing, the application of laser scanning to the digitization of three dimensional physical realities has become increasingly wi...
Chapter and Conference Paper
Three experiments were designed to investigate the color preference of User Interface of Chinese youth. Background color and foreground color, as well as their combinations were examined. The results showed th...

Chapter and Conference Paper
Eliminating semantic gaps is important for image retrieving and annotating in content based image retrieval (CBIR), especially under web context. In this paper, a relevance feedback learning approach is propos...
Chapter and Conference Paper
In this paper, we proposed a bayesian mixture model, in which introduce a context variable, which has Dirichlet prior, in a bayesian framework to model text multiple topics and then clustering. It is a novel u...
