Documenting Archival Automation Systems: Guidelines For The Project Manager, Austin Moller

Dissertations and Theses

With the onset of the information age, archivists are more frequently placed in professional situations where they must work with automated systems to manage the records in their custody. They must acquire new skills to use this technology, including system analysis, system planning, and the principles of computer operation. An area that is frequently neglected, however, is that of developing and maintaining in-house project documentation for systems once equipment is in place and implementation has begun. This oversight leads to poor training strategies, inconsistencies in input and output, and information loss when personnel changes occur.

Project documentation is the group …


Entropy Reduction Of English Text Using Variable Length Grouping, Vincent Norman Ast Jr. Jul 1972

Entropy Reduction Of English Text Using Variable Length Grouping, Vincent Norman Ast Jr.

Dissertations and Theses

It is known that the entropy of English text can be reduced by arranging the text into groups of two or more letters each. The higher the order of the grouping the greater is the entropy reduction. Using this principle in a computer text compressing system brings about difficulties, however, because the number of entries required in the translation table increases exponentially with group size. This experiment examined the possibility of using a translation table containing only selected entries of all group sizes with the expectation of obtaining a substantial entropy reduction with a relatively small table.

An expression was …
