Abstract : This report continues analyses into the automatic attribute assignment program of the Multi-List System using as basic data a large nonrandom sample of 38,402 DDC (formerly ASTIA) documents. The assignment program now has been extended to include the 599 most frequently used descriptors in the sample file; this comprises those used 72 times or more in the 38,402 documents and represents slightly more than 10% of the 5,577 different descriptors in the sample. In addition, a start has been made into analyzing the characteristics of the pair associations included among these 599 descriptors and some preliminary statistical data are contained in the report.
