| Abstract | With the explosive development of Internet and Social Networking Services (SNS), more and more people begin to get information from others. So how to find users, which have similar interests, is becoming an important issue. The traditional method is using a vector to calculate the similarities between user models. The similarities between user models are measured by one value. This method is very simple, but some useful details are lost. Users do not know where they are similar in detail. Particularly, the existing approaches cannot calculate the similarity between users under the different interest trees of user models. Aiming at solving these problems, a method which expresses and calculates the similarity between two user models in different granularities is proposed in this paper. Node Structure Similarity (NSS), Interest Theme Similarity (ITS), Comprehensive Interest Similarity (CIS) and Dynamical Comprehensive Interest Similarity (DCIS) are considered to describe the similarities between user models. NSS reflects to structural similarity of interest tree. ITS is the interest theme similarity between user's interest trees. CIS is a comprehensive similarity which has combined NSS with ITS. DCIS is not only calculated by NSS and ITS but also considered the weight of NSS and ITS. Experimental results show that DCIS is the most reasonable one among the three methods mentioned above. |

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.
