A situation-based approach to approximate truth
D. Osherson, Michael Stob, Scott Weinstein · 2002
The authors have been exploring an alternative approach to fuzzy logic which preserves the standard conception of set membership. Similarity between situations is used to construct a theory of approximate truth. The theory is embedded in a first-order logical framework, and an attempt is made to provide an intuitive understanding of its leading ideas. An algorithm is described for determining the approximate truth-value of predicate logic sentences in a given situation.>
