Abstract :
In the context of regular databases, fuzzy quantified statements of the type “Q X are A” have been widely studied. The main objective of this paper is to investigate the meaning of a more complex family of quantified statements of the type “Q B X are A”. Our approach is based on some behavioral properties of these statements and it is compared to preview propositions suggested for the interpretation of this class of statements
