Concept Based Retrieval in Digital Libraries

摘要

With the onset of the knowledge revolution from the early 1980s, the ICT witnessed the digitization of more and more amounts of information. This process led to the explosion of the size of the web and the creation of digital libraries throughout the world. The UDL mission itself aims to digitize as many as a million books. Under the Digital Library Initiative in India, more than 48,000 books are already available on the Internet.rnAs more and more documents continue to be made available globally to people in electronic form, the questions of metadata tagging, concept based navigation across virtual libraries and languages, and summarization assume significance. The present paper briefly discusses an Integrated Multilingual WordNet called the VNet for realizing an effective concept-based retrieval in a digital library and a summarization technique based on the Paninian Vibhakti system.rnWhile NL based solutions, address the disabilities of people with respect to their linguistic abilities, web-based digital libraries (DL) also call for accessibility irrespective of physical handicap. The paper also discusses the World Accessibility Initiative (WAI), a recommendation of the W3C and its relevance to web-based digital libraries.
