| Abstract | Accurate retrieval of entries from large directories is a difficult task. Practical systems attempt to achieve acceptable performance using dialog to restrict the size of the directory. For instance, knowledge of city and state can be used to restrict the entries in a telephone number retrieval application. It is shown that it is advantageous to use a voice form-filling paradigm in which the user speaks all the field entries, first name, last name, city, and state, in a single utterance. A two-pass method for form-filling presented recently (S. Parthsarathy et al., 2005) is evaluated on the directory retrieval task. A delayed network expansion and pruning method is proposed to improve the efficiency of short-list generation in the form-filling algorithm. Experimental results demonstrate that sentence accuracies greater than 85% can be achieved on directory sizes of up to 8 million entries, with modest computing requirements. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
