5. The method of claim 3 , wherein using the at least one cognitive motivation orientation confidence weight recorded for the first text sequence to determine a first dominant cognitive motivation orientation set expressed in the first text sequence comprises: maintaining normalized dominance thresholds, there being one normalized dominance threshold corresponding to each first text sequence cognitive motivation orientation weight score in one-to-one correspondence; identifying as dominant for the first text sequence each cognitive motivation orientation for which the corresponding normalized first text sequence cognitive motivation orientation weight score exceeds a corresponding normalized dominance threshold; and identifying as non-dominant for the first text sequence each cognitive motivation orientation for which the corresponding first text sequence cognitive motivation orientation weight score does not exceed the corresponding normalized dominance threshold.
3. The method of claim 2 , wherein using the at least one cognitive motivation orientation confidence weight recorded for the first text sequence to determine a first dominant cognitive motivation orientation set expressed in the first text sequence further comprises normalizing the first text sequence cognitive motivation orientation weight scores to obtain normalized first text sequence cognitive motivation orientation weight scores, there being one-to-one correspondence between the normalized first text sequence cognitive motivation orientation weight scores and the first text sequence cognitive motivation orientation weight scores.
