Business process reengineering frequently occurs in complex service systems because of its dynamic, random and varied running characteristics. To solve the problem, we proposed a novel SOA portfolio optimization algorithm based on value model and graph theory. Firstly, in order to strengthen the QoS analytical capacity of SOA, the value model is introduced into the SOA system to describe customer's...
Land resource security has come to be a popular issue, and the researches mainly focus on static evaluation of the level of land resource security. But the growing lack of land resource caused by various factors requests us turning our researches on land resource security to dynamic adjustment and control urgently. This paper describes a specific directed graph model on which the model of land resource...
Multiple Channel Design (MCD) has been adopted widely in wireless networks to increase throughput and reliability with relatively less energy consumption. Due to physical restrictions of sensor nodes, applying multiple radio channels in sensor networks poses significant challenges, particularly on energy consumption. To address such challenges, we propose an energy-aware MCD scheme called SmartChannel...
In this paper we study the effect of clustering coefficient on the evolution of cooperation in scale-free public goods games. Since the cooperator can feed back the investment to its cooperative neighbors through their common neighbor, the cooperative behaviors is easier to diffuse on the graph with triangle loops than that without loops. The feedback reciprocity mechanism of triangle discloses why...
Sentiment classification is very useful in many applications such as analysis of product reviews in e-business applications and media opinion mining. In this paper, a novel method to tag words sentiment automatically is proposed. In this method, a word association graph is firstly constructed from text corpus, i.e. product reviews, in which each node is a word and if there is an edge between two words,...
This paper introduces a robust fingerprint matching scheme based on the comprehensive minutia and the binary relation between minutiae. In the method, a fingerprint is represented as a graph, of which the comprehensive minutiae act as the vertex set and the local binary minutia relations provide the edge set. Then, the transformation-invariant and transformation-variant features are extracted from...
