| Abstract | In current theories of web navigation, link evaluation has been treated primarily as a bottom-up process involving assessing the semantic distance between a search goal and a given link in the information source. In this paper we investigate whether link evaluation could be subject to top-down influence from knowledge of the information source. We measured fixation durations that occurred during link evaluation and found shorter durations in the search for easy goals. This preliminary finding suggests that for goals with category names readily retrievable from knowledge of the information source, search is likely aided by top-down influences. |

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.
