Along with the development of grid computing and cloud computing, finite computing resources supplied by stand-alone server usually become the bottleneck in the process of system implementation of online trading platform. Moreover, It is difficult to reuse algorithm module and the system also becomes more complicated to achieve. Traditional online trading(More)
With the flourish of the Web, online review is become a more and more useful and important information resource for people. As a result, automatic review mining has become a hot research topic recently. Traditional review mining based on feature extracts product feature and opinion word independently, and seldom considers their association information. In(More)
Grid based computational infrastructure is a promising next generation computing platform for solving large-scale resources- intensive problems. With the developing Grid technologies and applications, the research on the Grid monitoring system gets increasingly essential and significant. As far as the present research are concerned, there exist two mainly(More)
The problem of data source discovery is a key issue in a data access and integration (DAI) system in the grid environment. This problem involves assigning data sources to tasks in order to satisfy task requirements and data source policies. These requirements and policies are often expressed in disjoint application and data source models, forcing a data(More)
The P2P data integration system aims to combine the advantages of P2P technologies and data integration to overcome centralized data integration systems' shortcomings. Kademlia, as a widely used and efficient network protocol for P2P files sharing system, has a very clear logical structure, and with its unique identifying pattern of nodes and XOR metric for(More)
Kademlia is one of the most popular routing algorithm based on DHT in P2P network research. It specifies the structure of the network and the exchange of information through node lookups. With the unique identifying pattern of nodes which kademlia adopts and XOR metric for distance, it contacts only O(log(n)) nodes during the search out of the total of n(More)
Considering the characteristic of heterogeneous wireless sensor networks, the clustering algorithm based on data content for heterogeneous sensor network is proposed. In cluster construction stage, according to the various sensor node types in CADC algorithm, the same types of nodes is divided into the same cluster and different types of nodes can not be(More)
