| Abstract | Visual data mining with virtual reality spaces are used for the representation of data and symbolic knowledge. The approach is illustrated with data from a geophysical prospecting case in which partially defined fuzzy classes are present. In order to understand the structure of both the data and knowledge extracted in the form of production rules, structure-preserving and maximally discriminative virtual spaces are constructed. High quality visual representations can be obtained using Samann and nonlinear discriminant neural networks. Rough set techniques are used for demonstrating the irreducibility of the set of original attributes and for learning the symbolic knowledge. Grid computing techniques are used for constructing sets of virtual reality spaces and for assessing the behavior of some of the neural network parameters controlling the quality of the virtual worlds. The general properties of the symbolic knowledge can be found with greater ease in the virtual reality space whereas both the prediction of unknown objects to the target class, as well as a derivation of a fuzzy membership function from the virtual reality space and the neural network results are obtained. |

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.
