This paper treat the query sentence as common sentence segmented from multi-documents set for multi-document summarization, and mixed it into sentences set, then this paper create efficient cluster algorithm to cluster all the sentences, The clusters which contain the query sentence will be merged to one cluster, and modified MMR will be used to extract summary sentences. Experimental result shows...
The paper presents three-layered key management architectures to MANET (Mobile Ad hoc networks) with three-layered virtual infrastructure. Two kinds of three-layered key management architectures are introduced. The communication efficiency of them has been analyzed. It also shows that the communication cost of the three-layered key management schemes is always smaller than that of the two-layered...
Grey relational analysis is an important part of the grey systems theory, and it is the basis of the grey clustering analysis, grey decision-making and grey controlling. In this paper, we provided the definitions of parallel, uniform and order-keeping properties. We constructed a new grey relational model. By theoretical proving we knew that the model is not only satisfied to the normality, whole...
This passage mainly in the study of grey vectors, how to solve the vector and vector function, as well as how to construct a vector between two gray fitting function relationship.
Based on the definition of absolute degree of grey incidence, which put forward by Professor Liu in 1992, a kind of new models for grey incidence analysis is given in this paper. The interrelations and influence can be measured by the new models with different visual angle of comparability and closeness respectively. And a simplified method to calculate the similitude degree of grey incidence and...
