Cut properties of resemblance

Vladimir Janiš, Magdaléna Renčová, Branimir Šešelja, Andreja Tepavčević (2010)

Kybernetika

Similarity:

The resemblance relation is used to reflect some real life situations for which a fuzzy equivalence is not suitable. We study the properties of cuts for such relations. In the case of a resemblance on a real line E we show that it determines a special family of crisp functions closely connected to its cut relations. Conversely, we present conditions which should be satisfied by a collection of real functions in E in order that this collection determines a resemblance relation. ...

A first approach to the multipurpose relational database server.

Ignacio J. Blanco, Carmen Martínez-Cruz, José María Serrano, M. Amparo Vila (2005)

Mathware and Soft Computing

Similarity:

In this paper, an architecture and an implementation of a multipurpose relational database server are proposed. This architecture enables classical queries to be executed, deductions to be made, and data mining operations to be performed on fuzzy or classical data. The proposal of this integration is to combine several ways of querying different types of data. In order to achieve this, a combination of existing meta-knowledge bases and new data catalog elements is presented. We also...
