Whereas the previous study concentrated on validating these syllogisms through the construction of formal proofs and semantic verification, the present work focuses on assessing their validity using Peterson’s grade-based rules.enfuzzy systemsmathematicsinformaticsfuzzy Peterson's syllogismsintermediate quantifiersgraded Peterson's square of oppositioninfo:eu-repo/semantics/conferencePaper519.1/.8 - Kombinatorika.
