A generalization of the OWA operator to evaluate non monotonic quantifiers
نویسندگان
چکیده
This paper is devoted to the evaluation of quantified statements in flexible querying of relational databases. Its contribution is a new approach based on the arithmetic on fuzzy numbers (Nf, Zf, Qf) expressing well-known but gradual numbers. The advantage of this proposition is that no particular assumption is made on the monotonicity of the linguistic quantifier. In addition, this approach is a generalization of the OWA-based evaluation.

COMBINING FUZZY QUANTIFIERS AND NEAT OPERATORS FOR SOFT COMPUTING
This paper will introduce a new method to obtain the order weightsof the Ordered Weighted Averaging (OWA) operator. We will first show therelation between fuzzy quantifiers and neat OWA operators and then offer anew combination of them. Fuzzy quantifiers are applied for soft computingin modeling the optimism degree of the decision maker. In using neat operators,the ordering of the inputs is not...

Borda count is a well-known social choice method, and is frequently used for group decision making problems. However it does not consider the optimism/pessimism view of the director, which has a great effect on the group decisions. Therefore in the present study, we extend the Borda method by using the Ordered Weighted Averaging (OWA) operator to consider the risk attitudinal characteristics....
متن کاملOrness and parameterized RIM quantifier aggregation with OWA operators: A summary
A necessary and sufficient condition for the ordered weighted average (OWA) aggregation value of an arbitrary aggregated set to consistently increase with the orness level is proposed. The OWA operator properties associated with the orness level are extended. Then, with the generating function representation of Regular Increasing Monotone (RIM) quantifier, all these conditions and properties ar...
متن کاملFuzzy quantifiers in sensitivity analysis of OWA operator
The efficient use of the Ordered Weighted Averaging (OWA) operator in decision making problems depends on the choice of the order weights. Using fuzzy quantifiers is one of the most popular methods to obtain them. In this study, a new method will be introduced for determining the order weights from the quantifiers, which is especially useful in the case of unimodal quantifiers. The new method i...
متن کاملType-1 OWA operators for aggregating uncertain information with uncertain weights induced by type-2 linguistic quantifiers
The OWA operator proposed by Yager has been widely used to aggregate experts’ opinions or preferences in human decision making. Yager’s traditional OWA operator focuses exclusively on the aggregation of crisp numbers. However, experts usually tend to express their opinions or preferences in a very natural way via linguistic terms. These linguistic terms can be modelled or expressed by (type-1) ...
