| Abstract | Information Retrieval systems have traditionally been evaluated in terms of efficiency and performance. These aspects of retrieval systems, whilst very important, do not cover a crucial aspect of the system, the access it provides to the documents of the collection. Retrievability, a document centric evaluation measure, introduced by Azzopardi and Vinay, provides an alternative approach to evaluation [1]. Retrievability is the ease with which a document can be retrieved using a retrieval system. The more queries which retrieve the document, and the higher up the document is returned, the more retrievable it is. It can thus be used to describe how difficult it is to find documents in the collection given a particular configuration of a retrieval system. Unlike typical performance evaluations, performing a retrievability analysis can be done without recourse to relevancy judgements meaning there is no reliance on a test collection. This has major advantages when tuning a retrieval systems parameters as the tuning can be performed on the live collection. |

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.
