Cluster Analysis and Research of the Resource in KAD
Chunhui Wang, Xingshu Chen, Qi Wu · 2012
With the development of P2P file sharing in recent years, KAD network has been widely used. Although there are a large amount of resources in KAD, few of them can meet the users' demands. In order to find useful rescources in KAD, We need a systematic analysis of its characteristics. Firstly, describe the file score qualitatively, and cluster the resources according to the file size and the file score. Then find out the resources' features in the network. And finally use the analysis result to evaluate the search result of eMule client, make the conclusion that now search engine of eMule client cannot well satisfy the users' needs. With the development of P2P technologies, sorts of P2P softwares emerged. One of the features of P2P network is anonymity so that users can freely upload any resources. And currently most P2P resources will be automatically uploaded after being downloaded, which causes large amount of various resources distributed widely and spreading quickly over the P2P network. Therefore, users will inevitably find a lot of useless resources during their search. eMule is a P2P file-sharing software with numerous users. eMule v0.42b is formally embedded with the KAD which is a P2P network with neither server nor central node. While KAD network increases the download speed and provides the user with more download sources, it allows users to upload resources more freely. Since KAD network is lack of central node or server which can verify the uploaded resources, it contains a wide variety of illegal resources. Now multitudes of people have done research on KAD network. Jie Yu et.al(3) studied the ID repetition in KAD network and illustrated its influence to the network. Steiner et.al(2) systematically measured node distribution and its online time in KAD network, and finally they found the abnormality due to the modified KAD client joining to the network. The paper applies the cluster analysis of data mining to analyzing the resources in KAD network. Now cluster analysis has been used in many industries and fields. In (11), the author uses it in traditional Chinese medical science to classify and diagnose disease. In (10), the cluster analysis plays a role in the analysis of Chinese mainland's investment environment. Besides, a P2P trust model based on cluster recommendation is proposed in (6). This paper is to: • Propose the standard of KAD network's resources meeting users' demands. • Describe the resources' features in KAD network through cluster. • Based to the analysis result, make a comprehensive evaluation to the search results of eMule client. The result shows that eMule client cannot meet users' demands well. 2. Background
