| Abstract | Relationship degree should be various between two entities, while static friend list in social network is incompetent to express the relationship divergence, thus tie strength is presented to quantitatively describe real social relation based on lots of features derived from historical data in online activities. We propose a model to measure tie strength within a user's social circle in Micro-blog by multivariate stepwise linear regression (MSLR). The model also determines the principle features that are affecting tie strength significantly from abundant features in Micro-blog. Features are mapped into four dimensions to excavate implications hiding behind them from abstract level by taking advantage of previous sociological study achievement. Thus, key dimensions for tie strength are also obtained. Then Native Bayesian Classifier is employed to test the performance of key features and key dimensions in distinguishing ties by strength values. We apply this model with the data derived from Sina Micro-blog and get approximately 80% accuracy of tie strength estimation. Seven principle features are obtained from nineteen ones. We conclude that principle features are consistent with key dimensions, which proves that the mapping processing is reasonable. |

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.
