| Abstract | The medical diagnosis process can be interpreted as a decision-making process during which the physician induces the diagnosis of a new and unknown case from an available set of clinical data and using his/her clinical experience. This process can be computerized in order to present medical diagnostic procedures in a rational, objective, accurate and efficient way. In the last few decades, many researchers have focused on developing effective methods for intelligent heart disease prediction and decision support systems. For such a system, high accuracy of prediction is paramount. In this research, an ensemble classifier is proposed, which uses majority vote-based scheme for heart disease data classification and prediction. The five heterogeneous classifiers used to construct the ensemble model are as follows: Naïve Bayes, decision tree based on Gini Index, decision tree based on information gain, memory-based learner and support vector machine. Five datasets from different data repositories are employed for testing the effectiveness of the ensemble model. Each dataset has different types of attributes, for instance binary, real, continuous, categorical, etc. Experimental results with stratified cross validation show that the proposed MV5 framework deals with all the attribute types. MV5 has achieved an accuracy of 88.52% with 86.96% sensitivity, 90.83% specificity and 88.85% f-measure. Comparison of proposed MV5 model with individual classifiers shows increase in average accuracy, sensitivity, specificity and f-measure of about 14, 11, 17 and 18% respectively. |

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.
