| Abstract | Legal documents play a basic role in discharging the law to the public, besides constituting learning material for students, researchers and legal practitioners. Legal documents contain text rich contents that can be structured and marked with description languages such as XML. This basic feature can be exploited by XML based retrieval models to return legal document parts that are more relevant as compared to the query results by the traditional Information Retrieval (IR) systems. Under different paradigms, legal documents are subject to change, as the laws they carry undergo modifications or amendments. The dynamicity of the law is manifested by the change in the legal documents, which may be caused for example by the socio-economic changes of the society that it is serving. This change in turn will have a sever consequence on the retrieval quality of the legal document retrieval systems. However, none of the legal document retrieval systems considered the dynamic feature of legal documents over time in their search and retrieval systems. In this work we propose a generic model for a change-aware legal document retrieval system using XML based IR approaches. Based on the model, we have designed the necessary algorithms to implement the system and developed a prototype system that demonstrates the validity of our proposed model. The experiments we conducted show that the system developed based on our model have a significant precision improvement. |

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.
