Optimization of Key-Sets, and Evaluation of Their Retrieval Efficiency	1974-09-01	13	.pdf	application/pdf	5376	650	81	Methods for optimization of key-sets are desc1·ibed, and the performance of key-sets varying in size between 150 and 300 is determined at file combining these key-sets with keys for the first and second initials were determined by applying them to the 50,000 name file, and the entropy value each ratio the keys were applied to the 50,000 name entries, and the distribution of the resultant descriptions determined. combined key-sets to the file of 50,000 names were determined. showed virtually no difference in terms of the relative entropy alone, although the total number of different entries differed slightly between keysets, and the highest value was used to choose the optimal set, detailed in Frequencies of Entries Represented by Optimal Key-Set of 296 Keys in a File of applicability of a key-set optimized for one file of 50,000 names to another various positions in the names, and to compare them with those of the optimal key-sets employed in the variety-generator approach.	./cache/8951.pdf	./txt/8951.txt
