Making fuzzy absolute and fuzzy relative orders of magnitude consistent

Fuzzy absolute and fuzzy relative orders of magnitude models are recalled. Then, the problem of the consistency of these models is addressed. The paper provides conditions under which the relation between quantities estimated in terms of fuzzy absolute labels can be expressed in terms of fuzzy relative orders of magnitude. Conversely, possible estimates in terms of fuzzy absolute labels are obtained from information about fuzzy relative and fuzzy absolute orders of magnitude.

An Approach Based on Predicate Correlation to the Reduction of Plethoric Answer Sets

Seeking data from large-scale databases often leads to a plethoric answer problem. A possible approach to reduce the set of retrieved items and to make it more manageable is to constrain the initial query with additional predicates. The approach presented in this paper relies on the identification of correlation links between predicates related to attributes of the relation of interest. Thus, the initial query is strengthened by additional predicates that are semantically close to the user-specified ones.
