A novel attributed community detection by integration of feature weighting and node centrality

نویسندگان

چکیده

Community detection is one of the primary problems in social network analysis and this problem has more challenges attributed networks. The purpose community networks to discover communities with not only homogeneous node properties but also adherent structures. Although been extensively studied, large a number attributes remains vital challenge. To address challenge, paper novel method developed by integration feature weighting centrality techniques. includes two main phases: (1) Weight Matrix Calculation, (2) Label Propagation Algorithm-based Attributed Detection. aim first phase calculate weight between linked nodes using structural attribute similarities, while, second phase, an improved label propagation algorithm-based proposed. detect different employing calculated matrix popularity. After implementing proposed method, its performance compared several other state art methods some benchmarked real-world datasets. results indicate that outperforms state-of-the-art ascertain effectiveness for detection.

Eigenvector-centrality - a node-centrality?

Networks of social relations can be represented by graphs and socioor adjacency-matrices and their structure can be analyzed using different concepts, one of them called centrality. We will provide a new formalization of a “node-centrality” which leads to some properties a measure of centrality has to satisfy. These properties allow to test given measures, for example measures based on degree, ...

A Novel Scheme for Improving Accuracy of KNN Classification Algorithm Based on the New Weighting Technique and Stepwise Feature Selection

K nearest neighbor algorithm is one of the most frequently used techniques in data mining for its integrity and performance. Though the KNN algorithm is highly effective in many cases, it has some essential deficiencies, which affects the classification accuracy of the algorithm. First, the effectiveness of the algorithm is affected by redundant and irrelevant features. Furthermore, this algori...

extremal region detection guided by maxima of gradient magnitude

a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...

CentralityDifferent Influence Models of Node Centrality in Transactional Community

This study investigates the various influence models of nodes' network centrality in the context of transactional community. Combining the Social Network Analysis (SNA) with Tobit regression, the research indicates that: i) a node's degree centrality (its followers) and betweenness centrality (the number of the shortest paths in which the node is included) have a positive impact on its network ...
