| Abstract | There are often enormous interactions among users of online social networking services. Based on their interactions and the corresponding contents, the users can be clustered into different interaction groups with different interests. In this paper, we propose a game-theoretic approach for formulating the dynamics of users' participation into interaction groups on a social network formed by users' interrelationships. A partition of the social network into interaction groups corresponds to an equilibrium of the game. In the proposed approach, the original interaction network is reduced to an effective one based on the attributes of interactions, where the proposed game is played. In the game, each node is represented by a selfish agent that performs actions to join or leave interaction groups according to its utility. An agent may belong to more than one interaction group because of its different interests, which is naturally captured by the proposed approach. The utility of an agent consists a gain function and a loss function. Specifically, we adopt a simple extension to the modularity of a social network as an agent's gain function and formulate the intrinsic cost paid by the agent for maintaining its interaction groups as its loss function. For the purpose of validation, we conduct experiments on a real-world data set collected from Facebook. The experimental results well demonstrate that the proposed approach is effective in identifying interaction groups in social networks. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
