| Abstract | The efficiency of concept lattice construction is a prevalent topic because it is necessary and important to construct concept lattice in many application fields concerning concept learning. This paper suggests a novel batch algorithm referring to the idea of isomorphic generating and closure operator. After context preprocessing in which the value and weight of objects are figured out, our algorithm could quickly generate all the possible concepts added by an object of context through using concept dictionary. Then we could obtain all the concepts after removing pseudo concepts from concept set. Our algorithm can reduce the search space when generating direct partial order relation easily between all concepts. Finally, our algorithm is completed as well as NextClosure algorithm using C# on windows platform, and comparison was made between them in the some data sets. Results showed that our algorithm performed better than NextClosure algorithm on temporal aspect. |

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.
