Once. A Test of Authorship Based on Words which are not Repeated in the Sample
A. Q. Morton · Literary and Linguistic Computing · 1986
The basic argument of the paper is that while the number of once occurring words varies in a complex manner, the number placed in different positions is characteristic of the writer. It is the position of these words that enables one writer to be distinguished from another. The problem is examined with reference to a sample of NT Greek prose and three plays by Shakespeare compared with two by Peele.
