Aplicación y ventajas del conector "y posiblemente" en busquedas bipolares sobre el modelo GEFRED

Abstract

Fuzzy databases have been implemented in corporate and organizational level as an efficient and effective tool to carry out searches with values that can be vague, unknown, incomplete or null. In the same way, developments about bipolarity have allowed user to raise more flexible queries in terms of their proximity to natural language. The aim of this paper is to implement the fuzzy operator “and possibly” proposed by the theory of bipolar queries, in the generalized model of fuzzy relational databases (GEFRED). With this aim in mind, in the first part it is addressed the theoretical aspects about bipolarity and the GEFRED model that allow to think about an integration between both theories. Then, through an application, it is proposed the needed procedures and the emerging advantages of use of fuzzy operator.
