Collective Behavior of social Networking Sites

Ashwini Vispute, Prerna Jadhav, Prof. P. V Kharat
2014 IOSR Journal of Computer Engineering  
In this work, we predict collective behavior in social media. In particular, given information about some individuals, how can we infer the behavior of unobserved individuals in the same network?  ...  The scale of these networks entails scalable learning of models for collective behavior prediction.  ...  Acknowledgments We are done project on collective behaviour of social networking sites our college Jspm's BSIOTR.  ...

A hidden treasure? Evaluating and extending latent methods for link-based classification

Aaron Fleming, Luke K. McDowell, Zane Markel
2014 Proceedings of the 2014 IEEE 15th International Conference on Information Reuse and Integration (IEEE IRI 2014)  
Research on link-based classification (LBC) has studied how to leverage these connections to improve classification accuracy. This research broadly falls into two groups.  ...  First, there are methods that use the original attributes and/or links of the network, via a link-aware supervised classifier or via a nonlearning method based on label propagation or random walks.  ...  ., words in the page) to predict its label. In contrast, link-based classification (LBC) [1] , [2] also uses, for each node, the attributes or labels of neighboring pages as model features.  ...

Structural Neighborhood Based Classification of Nodes in a Network

Sharad Nandanwar, M. N. Murty
2016 Proceedings of the 22nd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining - KDD '16  
Classification of entities based on the underlying network structure is an important problem. Networks encountered in practice are sparse and have many missing and noisy links.  ...  For classifying a node, we take a random walk from the node and make a decision based on how nodes in the respective k th -level neighborhood are labeled.  ...  the node under consideration based on the collective behavior of its first-level neighborhood.  ...
