| Abstract | Rapid retrieval of specified items in a large amount of multi-dimensional data has become an urgent and challenging topic for improving the effectiveness of data searching and analysis approaches. In order to help users quickly re-find the desired items, we present a novel multi-perspective visual retrieval method which is totally different from traditional visualizations for searching results, such as list-based techniques. In our prototype, customized dimensions are generated adaptively which enables users to fast approach to the desired targets from multiple perspectives. We also design several display modes to layout the items by introducing degree-of-interest(DOI) ranking, which is implicitly defined by the geometric relationships of different dimensions. The display modes includes the Cluster Mode using importance-driven dimensionality reduction techniques, the Radial Mode diffusing the items into separate directions, the Uniform Mode evolved by Archimedean Spiral which keeps items non-overlapping and the Custom Mode for deep analysis. Moreover, we combine Focus + Context, Visual Cues which presents item properties, Collaborative Filtering and animations to recommend results according to the features users are interested in. Finally, we evaluate our method in different scenarios: text message retrospection, desktop search and web browsing history retrieval. The experiments show that our method is flexible, extensible, and efficient. |

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.
