The flow of information in the network currently existing attacks and malicious damage, a privacy protection algorithm based on the maximum greedy is proposed, the data privacy acts as weights between nodes in network diagram , change these weights to achieve the protection of important data, by obtaining the shortest path way to ensure that efficiency is not influenced ,the experimental results show...
Abstract-Scientific and technical literature is a useful resource where people can extract interesting knowledge or patterns by text mining tools. Text mining technologies have been widely used to reveal topics and the structure of topics. In this paper, the selected articles in the form of textual data are represented by the network structure at first, and then text clustering algorithm is applied...
Presently, in the data mining scenario clustering of large dataset is one of the very important techniques widely applied to many applications including social network analysis. Applying more specific pre-processing method to prepare the data for clustering algorithms is considered to be a significant step for generating meaningful segments. In this paper we propose an innovative clustering technique...
Despites the great interest caused by social networks in Business Science, their analysis is rarely performed both in a global and systematic way in this field: most authors focus on parts of the studied network, or on a few nodes considered individually. This could be explained by the fact that practical extraction of social networks is a difficult and costly task, since the specific relational data...
Spectral clustering is a data mining method used for finding patterns in high dimensional datasets. It has been applied effectively to solve many problems in signal processing, bioinformatics, etc. In this paper spectral clustering was implemented to find students' patterns of behavior in an elearning system, to explore the relationship between the similarity of students'behavior and their academic...
Extremist political movements have proliferated on the web in recent years due to the advent of minimal publication costs coupled with near universal access, resulting in what appears to be an abundance of groups that hover on the fringe of many socially divisive issues. Whether white-supremacist, neo- Nazi, anti-abortion, black separatist, radical Christian, animal rights, or violent environmentalists,...
Cluster analysis describes the division of a dataset into subsets of related objects, which are usually disjoint. There is considerable variety among the different types of clustering algorithms. Some of these clustering algorithms represent the dataset as a graph, and use graph-based properties to generate the clusters. However, many graph properties have not been explored as the basis for a clustering...
The most important feature of Internet forums is their social aspect. Many forums are active for a long period of time and attract a group of dedicated users, who build a tight social community around a forum. With great abundance of forums devoted to every possible aspect of human activity, such as politics, religion, sports, technology, entertainment, economy, fashion, and many more, users are able...
