| Abstract | This paper proposes a method for automatically generating a multimedia encyclopedia from video clips using closed-caption text information. The goal is to automatically index each video segment of the television program by the principal video object. We focus on several features of the closed-caption text style in order to identify the principal video objects. Using Quinlan's C4.5 decision-tree learning algorithm and the predicted accuracies of production rule indicators, one object noun is extracted for each video shot. To show the effectiveness of the method, we conducted experiments on the extraction of video segments in which animals appear in twenty television programs on animals and nature. We obtained a precision rate of 74.6 percent and a recall rate of 51.4 percent on the extraction of video segments in which animals appear, and generated a multimedia encyclopedia comprising 322 video clips showing 82 kinds of animals |

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.
