| Abstract | The comprehensibility of a model is very important since the results should be ultimately be interpreted by a human. This paper presents a new machine learning method, named feature decomposition method based on rough set theory, to discover concept hierarchies and develop a multi-hierarchy model of database. First the features with more relations are selected into a feature group. Then some measures by rough set theory are presented in this paper. According to these measures, the objects defined on the proposed feature group are labeled to discover a new concept. The new concept hierarchies of the database usually have specific meaning, which increase the transparency of data mining process. Finally the rule induction can process on the concept hierarchies of the database to develop a new multi-hierarchy model. The idea presented is illustrated with examples and datasets from UCI machine learning repository. The results show that the multi-hierarchy model established by feature decomposition method can get high classification accuracy and have better comprehensibility. |

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.
