On a fuzzy querying and data mining interface

Janusz Kacprzyk, Sławomir Zadrożny (2000)

Kybernetika

Similarity:

In the paper an interface is proposed that combines flexible (fuzzy) querying and data mining functionality. The point of departure is the fuzzy querying interface designed and implemented previously by the present authors. It makes it possible to formulate and execute, against a traditional (crisp) database, queries containing imprecisely specified conditions. Here we discuss possibilities to extend it with some data mining features. More specifically, linguistic summarization of data...

Modeling a fuzzy coprocessor and its programming language.

Ricardo García Rosa, Teresa de Pedro Lucio (1998)

Mathware and Soft Computing

Similarity:

A computational model for a fuzzy coprocessor (types and structures of data and the set of instructions) is proposed. The coprocessor will be charged only of the typical operations of fuzzy logic as calculating membership degrees, unions and intersections of fuzzy sets, fuzzy inferences, defuzzifications and so on. One main novelty is that the programming language admits fuzzy rules conditions in which there would be linguistic edges preceding the predicates and the coprocessor is designed...

An elemental processor of fuzzy SQL.

Juan Miguel Medina, Olga Pons, M. Amparo Vila (1994)

Mathware and Soft Computing

Similarity:

This paper reports an alternative for implementing an SQL fuzzy extension on a Fuzzy Relational Database System. This proposal tries to build an FSQL processor using representation and manipulation mechanisms offered by the RDBMS which operates as a host. For this purpose, we are based our work on the formulation of a theoretical model of Fuzzy Relational Databases, on the adoption of a scheme for the representation and implementation of fuzzy information on conventional RDBMS, and on...
