| Abstract | Constraint-based recommenders support users in the identification of interesting items from large and potentially complex assortments. In cases where no recommendation could be found for a given set of requirements, such systems propose recommendations that indicate minimal sets of faulty requirements. Unfortunately, such recommendations are not diversified and do not include repair proposals which triggers a low degree of satisfaction and frequent repairs of recommendation sessions. This paper presents a dynamic and diversity relaxation approach that integrates the calculation of similarity requirements of customers and recommended products resulted in each atom of customer query and the cost of each atom of customer query. The Algorithm DDn Relax returning ¡®at-least-n' products can be efficiently solved diversified preference of customer. |

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.
