Inferring agent dynamics from social communication network

Content Provider ACM Digital Library
Author Goldberg, Mark Chen, Hung-Ching Justin Wallace, William A. Magdon-Ismail, Malik
Abstract We present a machine learning approach to discovering the agent dynamics or micro-laws that drives the evolution of the social groups in a community. We set up the problem by introducing a parameterized probabilistic model for the agent dynamics: the acts of an agent are determined by micro-laws with unknown parameters. Our approach is to identify the appropriate micro-laws which corresponds to identifying the appropriate parameters in the model. To solve the problem we develop heuristic expectation-maximization style algorithms for determining the micro-laws of a community based on either the observed social group evolution, or observed set of communications between actors. We present the results of extensive experiments on simulated data as well as some results on real communities, e.g., newsgroups.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
