摘要：Classical logic has a serious limitation in that it cannot cope with the issues of vagueness and uncertaintyinto which fall most modes of human reasoning. In order to provide a foundation for human knowledgerepresentation and reasoning in the presence of vagueness, imprecision, and uncertainty, fuzzy logicshould have the ability to deal with linguistic hedges, which play a very important role in the modificationof fuzzy predicates. In this paper, we extend fuzzy logic in narrow sense with graded syntax, introduced byNova´k et al., with many hedge connectives. In one case, each hedge does not have any dual one. In theother case, each hedge can have its own dual one. The resulting logics are shown to also have the Pavelkastylecompleteness.
