| Abstract | Evaluation of video summarization approaches requires more information on the user-perceived qualities of different types of summaries. Also, evaluation measures need to be further developed in a user-led manner. This article reports on a user-centered evaluation of visual video summaries. Four types of summaries (fastforward, user-controlled fastforward, scene clips, and storyboard) were evaluated with a set of existing performance and satisfaction measures. A repertory grid elicitation was conducted with our participants gathering evaluation constructs related to both video summary content and controls. Results showed a lack of correlation between performance and satisfaction measures. User-supplied evaluation constructs were shown to span both the performance and satisfaction dimensions of the video summary evaluation space. Most constructs achieved moderate to good inter-rater agreement in a consequent survey. Free descriptions of videos and respective summaries showed that while users are able to interpret object- and event-related information from short summaries, thematic inference lacked, leading to worse descriptions than for the full videos. |

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.
