With the exploration of the Internet, the data gathering from the Web is a challenge task. Both the traditional Client/Server (C/S) scheme and the new Mobile Agent (MA) scheme have their advantages and shortcomings. In this paper, a hybrid data gathering scheme is proposed based on minimum cost principle i.e. the minimum data transferred or the minimum running time. Through the analysis for C/S scheme...
The associations between different modalities of Web images could be very useful for Web image retrieval. In this paper, we investigate the multi-modal associations between two basic modalities of Web images, i.e. keyword and visual feature clusters, by data mining technique. The association rule crosses two modalities, in which the antecedent is a single keyword and the consequent is several visual...
Latent Semantic Indexing (LSI) and Relevance Feedback (RF) have been shown to be extremely useful in information retrieval respectively. But at the context of Web image retrieval, LSI is limited for the Single Value Decomposition (SVD) computation cost to large dataset while RF is confused with the reluctance of interaction for most Web users. In this paper, a Pseudo Relevance Feedback approach based...
A mobile agent based data gathering system for Web image retrieval is proposed in this paper. In our system, the data gathering system are implemented as mobile agents that can run on the remote servers, which lead to most computing intensive tasks, i.e. feature extracting, indexing , can be parallelized and carried out on different remote Web servers. It makes a great improvement in processing speed...
The design and implementation of ambulances that exchange high quality video, vital signs, voice and text communications, and patient information in real-time with the emergency room are becoming a reality. For instance, the Disaster Relief and Emergency Medical Service (DREAMStrade) project has developed such ambulances. Through wireless Internet access, the ambulances take advantage of the widespread...
