| Abstract | User behavior information has proved valuable for inferring document relevance, but its role in deducing relevance at the passage/section level is not well explored. In this paper, we study how user behavior information implies section relevance, and use this information to improve section ranking. More specifically, we focus on four types of user search behavior that occur while browsing a document -- dwell time, highlighting, copying and clicks at the section level. Experimental results based on a commercial query log show that user behavior information can significantly improve section ranking. While section-level click information is a very powerful signal of relevance, it depends on an interface supporting section-level links. We find comparable levels of gain using other behavior information that does not depend upon such an interface. |

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.
