Compression of Bibliographic Data Bases Using a Variable to Fixedlength Bitstring Coding Transformation

Compression of Bibliographic Data Bases Using a Variable to Fixedlength Bitstring Coding Transformation

The application of a variable to fixedlength compression coding technique to two bibliographic data bases MARC and INSPEC is described. By appropriate transformation of characters or digrams into bit patterns reflecting more accurately the distributions of characters in the data bases, and applicati...

description The application of a variable to fixedlength compression coding technique to two bibliographic data bases MARC and INSPEC is described. By appropriate transformation of characters or digrams into bit patterns reflecting more accurately the distributions of characters in the data bases, and application of the encoding process, varying degrees of compression can be obtained.
