Title

Application of OCR in building bibliographic databases

Abstract

Bibliographic databases tend to be very verbose and pose a problem for libraries due to the huge amount of data entry involved. In this situation, technologies that offer solutions are retrospective conversion and OCR. Discusses the building of an intelligent system for the automatic identification of bibliographic elements such as title, author, publisher, etc. Considers the resolution of conflicts in situations where more than one bibliographic element satisfies the criteria specified for identification. This work is being carried out at the Indian Documentation Research and Training Centre, Bangalore, with the financial assistance of NISSAT (National Information System for Science and Technology)
