A novel text analysis and characterization method involves the generation from text samples of sets of variable-length character strings. These sets are intermediate in number between the character set and the total number of words in a data base; their distribution is less disparate than those of either characters or words. The size of the sets…

The Effectiveness of Weights and Links in Automatic Indexing. Project MEDICO Second Progress Report.
Artandi, Susan; Wolf, Edward H. – 1968
This report describes work concerned with the statistical evaluation of the output of MEDICO automatic indexing procedure. The statistical tests were designed to examine the validity of the assumptions which formed the bases of the indexing algorithms with primary emphasis on the algorithm development for the computation of weights and links. Some…

Fried, J.B.; And Others – 1968
The objectives of this research were to investigage (1) the feasibility of an index simulator, and (2) the use of a sequential analysis model for the automatic classification of documents. Index simulation was studied in general for various types of indexes, and in depth for the simulation of an inverted coordinate index to a document collection…
