Phrase Dictionary Distribution Analysis and Growth Prediction Report.
Abstract
The report describes a study of the DDC Phrase Glossary. It includes a computer program to tabulate word frequencies for blocks of phrases of optional sizes. On the basis of these distributions, empirical and statistical analyses are made including two prediction models. Two-word distributions are also included. Based upon the available distributions, a two-word Phrase Glossary size of 320,000 two-word phrases was determined. Also included are analyses of various techniques, such as suffix truncation, imbedded phrases, and query effectiveness. Comparisons are made of the DDC system to other plain language machine retrieval systems. (Author)
