Chinese word segmentation is the initial step for Chinese information processing. The performance of Chinese word segmentation has been greatly improved by character-based approaches in recent years. This approach treats Chinese word segmentation as a character-wordposition-tagging problem. With the help of powerful sequence tagging model, character-based(More)
In Ad Hoc networks, some malicious nodes broadcast plenty of useless route request packets in order to occupy the resources. To prevent these flood attacks. This paper proposed a improved protocol mechanism including validity test and packets buffer. Then this mechanism has been implemented based on protocol AODV in Network Simulator (NS) and the simulation(More)
Data mining is a new filed in data processing research. Support Vector Machine (SVM) is a useful method adopted in data mining. However, when the training set of the SVM contains information of uncertainty, the SVM can do nothing about it. In order to solve the problem presented above, this article discusses an algorithm of nonlinear Support Vector(More)
