【Abstract】 Counterterrorism goes deep into every country of the world.The technology of digital counterterrorism has been studied extensively with the aim to mine the clues or traces of terrorists,to analyze the terrorist organization and to predict the terrorist.The contributions of this paper include:(1) Proposing an algorithm called ASRA (Attribute Selected and Rule Abstracted) based on Support Vector Machine to classify community members by means of removing the useless attributes,which improves the accuracy of classification;(2) Proposing an approach called GVC(Generate Virtual Community) based on tree structure;(3) Designing an algorithm called SKS(Search Kernel Structure) to find kernel members of the virtual community.By intensive experiments demonstrating the effectiveness of SKS,the results show that the average cost of searching has been reduced by 33%.更多还原
