The report is a continuation of “Preliminary Studies for Machine Generated Index Vocabularies”, A. R. Meetham (1963) Language and Speech, 6, 22. It assumes that documents employ words from particular groups connected with their subject matter, and discusses four methods, two of them new, for finding the groups. They are picked out from a word list by using a word-word binary matrix to represent the associations between pairs of words. In an evaluation, the method which consumes least computer time turns out also to be the best.
