A large-scale image retrieval system for the WWW, named VAST (VisuAl & SemanTic image search), is presented in this paper. Based on the existing inverted file and visual feature clusters, we form a semantic network on top of the keyword association on the visual feature clusters. The system is able to automatically combine keyword and visual features for retrieval by the semantic network The combination is automatic, simple, and very fast, which is suitable for large-scale web dataset Meanwhile, the retrieval takes advantage of the semantic contents of the images in addition to the low-level features, which remarkably improves the retrieval precision. The experimental results demonstrate the superiority of the system.
The algebra-based and ontology-based information retrieval model are investigated in this paper, from which we know the two reinforce each other to some extent. Based on this observation, an integrated method for info...

In order to achieve low delay services in VoIP, we can use application-layer routing scheme, which is to find proper relay nodes to intermediate voice packets from the source peer to the destination peer. The difficulty of the scheme is how to find the proper relay nodes, which we call relay problem. This paper presents a new application-layer routing scheme, called DPLM, to resolve relay problem. We introduced the mechanism in detail, and evaluated our mechanism in NS2 network simulation environment and got a high relay node hit ratio result, which confirms the feasibility of a real system. Also we make a comparison with traditional schemes, and the results show that DPLM scheme has good performances. Copyright 2008 ACM.
