| Abstract | Digital libraries generally offer an efficient information retrieval (IR) thanks to the use of the metadata approach to the indexation of its collection. However, when the amount of the collection is large, a traditional IR is not efficient. This paper proposes an adaptive IR system applied to Digital Libraries. In this system, the user profile is considered during the information retrieaval using the metadata approach. In our proposal, the user profile is automatically updated regarding the characteristics of the accessed documents. Based on this profile, the documents satisfying the search criterion of a query are organized in relevance groups and in each group the documents are ordered by a criterion. Both, the grouping and ordering criteria are chosen by the user.Bibliotecas digitais geralmente oferecem um modo eficiente de recuperação de informações (RI) graças à adoção da abordagem de metadados para a indexação da coleção. Mesmo assim, quando o volume da coleção é muito grande, uma RI tradicional não é eficiente. Este artigo propõe um sistema de RI Adaptativa aplicado a bibliotecas digitais. Neste sistema, o perfil do usu´rio é considerado durante a busca de informações usando a abordagem por metadados. Em nossa proposta, o perfil do usu´rio é automaticamente atualizado com base nas características dos documentos consultados. Baseado neste perfil, os documentos que satisfazem o critério de busca são organizados em grupos de relevância e em cada grupo os documentos são ordenados por um determinado critério. Tanto o critério de agrupamento quanto de ordenação são escolhidos pelo usu´rio. |

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.
