| Abstract | In the recent years, a hot research topic in the literature is designing useful learning diagnosis systems. In order to set up effective parameters that are frequently used in the learning platforms, we advance three types of learning parameter improvement mechanisms in this article. The proposed learning parameter improvement mechanisms have three useful points: the first is that it can calculate the students' effective online learning time; the second is that the portion of a message in discussion section which is strongly related to the learning topics can be extracted; the third is plagiarism in students' homework can be detected easily. Then we feed the derived numeric parameters into a Support Vector Machine (SVM) classifier to predict each learner's performance so as to verify whether they reflect the student's studying behaviors. The results from experiments show that the prediction rate for the SVM classifier can be increased up to 35.7% in average after the inputs to the classifier are ' 'purified'' by the learning parameter improvement mechanisms. This great achievement reveals that the proposed algorithms indeed produce the effective learning parameters for commonly used e-learning platforms in the literature. |

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.
