A chapter in The Ordered Weighted Averaging Operators, 1997, pp 258-274 from Springer

Abstract: Abstract The use of OWA operators has been widely used in database contexts to process flexible queries where linguistic quantifiers are involved. This paper is devoted to comparing these operators’ use with other ways of addressing the same problems such as the Zadeh’s approach. Furthermore a new proposal is presented in order to avoid some inconveniences which the former approaches have in a wider class of problems. Finally, the paper analyzes the different types of queries with linguistic quantifiers which may appear in connection with relational databases and proposes the most appropiate way to solving them,in each case.
