| Abstract | Uncertainty is a state of lack of certainty, where having incomplete information can make system impossible to describe the desired outcome. Uncertainty of data is inevitable in every database in which data changes takes place frequently. As models of the real world, databases are often permeated with forms of uncertainty, including incompleteness, ambiguity, vagueness, inconsistency and imprecision. There is need to remove uncertainty in databases. Automatic elimination of uncertainty would make a real time application more efficient and reduce the human work. In this paper, we apply the Business Intelligence technique called k-means clustering and Bayesian network for reduction of uncertainty in database. The framework of Business Intelligence on Uncertain Events (BI_UnEvent) processes the uncertain events efficiently. Experimental results on the alumni database of Pondicherry Engineering College (PEC) data set show the novelty of our approach in removing uncertainty. It is observed that the proposed technique performs better in terms of processing time and precision when applied to College alumni database data sets compared to a Bayesian Network based approach. |

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.
