| Abstract | Visualization techniques of all sorts suffer from visual cluttering, the occlusion of visual information due to the overlap of graphical items; and from excessive complexity in analytical tasks due to multiple parallel perspectives. To cope with these problems, we introduce Hierarchical Visual Filtering, a novel interaction principle based on pragmatic and epistemic actions. Pragmatic actions here mean that the analyst is able to visually select and filter information, determining visual configurations that reveal different perspectives; epistemic actions mean that the analyst can record, annotate, and recall intermediate visualizations created pragmatically. To do so, we use a tree-like organization to keep multiple visualization workspaces linked according to the analytical decisions took by the user. Our goal is to promote an innovative systematization that can augment the potential for database visual inspection, and for visualization systems in general. It is our contention that Hierarchical Visual Filtering can inspire a novel scheme of visualization environments in which space limitations and complexity are treated by means of interactive tasks. |

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.
