| Abstract | In Data Mining there is a constant need to provide more scalable tools in order to tackle new domains with an increased level of complexity. Over the last few years one of the main challenges in this field is the growing size of the available data, owing to the level of data generation and storage capacities provided by new emergent technology, a range of new computational paradigms and parallel architectures have been proposed. MapReduce got the leading role in the field of Big Data applications since its appearance, and many popular Data Analysis tools and techniques have been successfully adapted to this paradigm. Supervised classification is one of the most common problems in Data Mining, and Bayesian Networks Classifiers (BNC) have become one of the most extended and competitive techniques to approach them. In this paper we propose a parallel definition of the KDB (k-dependence Bayesian classifier) algorithm under the MapReduce framework. We focus on obtaining maximum scalability and flexibility by exploring the concepts of vertical and horizontal parallelism, thus addressing both Big Data and High Dimensional problems simultaneously. We analyse its properties and the advantages of applying it to large datasets of different nature. Finally, an experimental evaluation is performed by testing a Hadoop implementation of our proposal on a high-end cluster of computers. |

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.
