  annote = {Interval-valued fuzzy sets are based on the algebra of
    subintervals of the unit interval [0,1]. We study valuations as a
    special type of measures on this algebra. We present a description
    of all valuations which preserve the standard fuzzy negation and
    extend the identity on the elements of the form
    (x,x). Consequences for sublattices are formulated.},
