Inferences with Higher Level Chain Sets

  • Ellen Hisdal née Gruenwald
Part of the Studies in Fuzziness and Soft Computing book series (STUDFUZZ, volume 14)


We have seen in sect. 6.3 that IF THEN questions
$$qu = IF\;A\;THEN\;{\text{C}}$$
cannot be answered by constructing the chain set representation over the ground universe {A, C} of the question as a whole because chain sets for IF THEN have no possibility row; and that such questions are answered on the basis of the separate chain sets for A and C respectively. Consequently we have not yet any method for answering a question qu’ which is a negation of an IT question
$$qu' = \neg qu = NOT(IF{\text{ }}A{\text{ }}THEN{\text{ }}C)$$
