As the rapid development of social media, now massive data are produced every day. We need to know about users' view and comment on a hot event so that the government and relevant departments can control and guide public opinion, and people can have a correct understanding of the event. So it is necessary to analyze these data. While it is difficult to dig out sufficient information from these data...
After studying the current principle andarchitecture of antivirus gateway for Web security detection, we found that the conventional virus scan is based on filescanning, which takes significant processing time. Whenscanning big size files, it may often cause disconnection of filetransferring with a time-out error message prompted out. Tosolve the problem of slow file virus scan, we propose a newmethod...
In the management of the online public opinion and Internet intelligent information, people need to obtain the content of the forum threads for further research on the topic emotion and the dissemination of forum topics. This paper presents a method based on templates to extract web forum contents. Proposed method overcomes the problem which caused by the change of the web pages structures and contents,...
The random packet sampling method is the simplest methodology for reducing the amount of packets that the network monitoring system has to process. However, the accuracy of anomaly detection is affected by the fact that this method biases a large IP flow. In order to reduce the impact of sampled traffic on network anomaly detecting, an adaptive traffic sampling method is proposed. This method is developed...
The capacity problem of Web server can be solved by Web cluster technology. The key point is load balancing strategy and algorithm. Traditional strategies are effective to some kinds of Web sites, but not suitable for all. A load balancing strategy and algorithm supporting QoS in Web cluster is proposed in this paper. The simulation experiments show that the system has better capacity.
