The resulting categories are presented in a 5 x 9 matrix as Figure 4 . Totals for each portion of Figure 4 are given in Figure 5 . The arbitrary guidelines governing this classification experiment would have required that a factor seven constraint be used instead of allowing the data to form nine-fold groups. These are an interplay of prime numbers and factors bringing out different degrees of richness. In further work the polarities could be clustered under a variety of matrix patterns as quite separate exercises.
Ambiguities arising from multiple connotations Clearly ambiguities are rife.
It is not to be expected that any results will be strikingly satisfactory. There is much confusion and overlap in usage. Many distinctions are not clearly established or maintained. Since links have to be made to problem entries based on documents, excessive rigidity in terminology would appear contrived and counterproductive. Roget is considered as a major guideline but cannot be considered the final pattern to be sought, and hopefully further clarification will emerged sometime in the future.
