Description
Summary:Two criteria are suggested which ensure complete algorithmization of automatic construction of a classification of terms. The criteria are based on statistical techniques. Two methods for automatic construction of classifications based on the factor analysis are described as in an automatic indexing method based on one of the classifications derived. The findings of a computer-based experiment are given. Edited machine trans. of Nauchno-Tekhnicheskaya Informatsiya. Seriya II: Informatsionnye Protessy i Sistemy (USSR) n11 p5-12 1970, by Charles T.
