Figure 2
From: Universal sequence map (USM) of arbitrary discrete sequences
Cross-tabulation of similarity between positions of the two stanzas. The figures can be reproduced using accompanying web based USM tool (see Abstract for URL address, test data also included), a) forward distance, d f (Eq. 4); b) backward distance, d b (Eq. 4); c) bi-directional similarity, D, compensated for φP 3 = 0.55,n = 4.25 (Eq. 11). Notice that the values of diagonals between similar segments estimate the number of units in the segments, although each D value is computed solely from a single pairwise comparison of UCM coordinates; d) Compounded similarity, dc, with a maximum for the mid-position of the similar segments (Eq. 12).
