| Abstract | Link prediction is a fundamental task for analyzing complex networks which has been widely used in many domains, such as, identify spurious interactions, extract missing information, evaluate complex network evolving mechanism. There exist a variety of techniques for link prediction, ranging from node similarity-based methods to probabilistic graphical models. Node similarity-based methods have low algorithm complexity and low time consumption merit. Moreover, these methods can obtain good prediction accuracy, therefore node similarity-based method have become the mainstream technique. However, most of similarity-based link prediction methods only take into account the role of each common neighbor equally to the connection probability of two nodes. In addition, these methods only take into account the contribution of each 2 hops common neighbor. In fact, 3 hops common neighbor also give valuable contributions to the connection likelihood. In this paper, we propose a model for link prediction, which is based on 2 and 3 hops common neighbors. In our model, each 2 or 3 hops common neighbor plays a different role to the node connection probability according to their degrees. Extensive experiments were conducted on six real-world networks. Compared with the representative node similarity-based methods, our proposed model can provide more accurate predictions. |

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.
