Research @ DRTC

DRTC work on the philosophy that education and research should go hand in hand.  DRTC has been engaged in the frontier and allied areas of research in library and information science and ensures all the students and researchers are exposed to the latest information management skills and acquire skills to be efficient leaders for the society to bring about the change. Some of the areas, where our faculty and research scholars are engaged in research are:

  • Faceted Classification
  • Knowledge Representation
  • Natural Language Processing
  • Computational Linguistics & Analysis
  • IT Applications to Information Services
  • Scientometrics
  • Knowledge Management
  • Web-based information services
  • Information Organization
  • Information Retrieval & Systems
  • Ontologies & Taxonomies Development
  • Information Systems & Services
  • Digital Libraries
  • Knowledge Classification & Systems
  • (Research) Data Management
  • Semantic Web Technologies

Some of the significant examples of DRTC's contributions are as follows:
