Fuzzy logic systems have played significant role in computer information system, specifically in quality, reliability and safety of databases and information retrieval. This work deals with theory of spatial databases, spatial data infrastructure and automated map generalizations in multi scale map spaces. We put forward the definitions of spatial similarity relation in automated map generaliza...

This paper proposes an effective framework for interactive region-based image retrieval. By utilizing fuzzy coarse segmentation and the graph structure for representing each image, the retrieval process was performed by measuring the image similarity according to the graph similarity. To assess the similarity between two graphs, fuzzy inter relations among regions feature vectors and spatial di...

Association rule mining approaches traditionally generate rules based only on database contents, and focus on exact matches between items in transactions. In many applications, however, the utilization of some background knowledge, such as ontologies, can enhance the discovery process and generate semantically richer rules. Besides, fuzzy logic concepts can be applied on ontologies to quantify ...

In this paper we present the main features an implementation details of a programming language that we call Bousi∼Prolog. It can be seen as an extension of Prolog able to deal with similarity-based fuzzy unification (“Bousi” is the Spanish acronym for “fuzzy unification by similarity”). The main goal is the implementation of a declarative programming language well suited for flexible query answ...

We present a new fuzzy logic programming Language, called LIKELOG, to be used for approximated reat;oning and for fuzzy deductive database applications. The core component of the system is the algori thm of unification, which expands the Martelli-Montanari unification algorithm introducing two similarity relations. The resolution mechanism is a straightforward application of this kind of expand...

In this paper, we propose new method to calculate the distance between intuitionistic fuzzy sets (IFSs) based on three dimensional representation of IFSs and analyze relations similarity measure IFSs. Finally, apply proposed measures pattern recognitions.

In this article we apply a new measure of similarity to analyse the extent of agreement in a group of experts. The proposed measure takes into account not only a pure distance between intuitionistic fuzzy preferences but also examines if the compared preferences are more similar or more dissimilar. The agreement of a whole group is assessed via an aggregation of individual testimonies expressed...

In [7] Maria I. Sessa extended the SLD resolution principle with the ability of performing approximate reasoning and flexible query answering. The operational mechanism of similarity-based SLD resolution can be used as the basis for a new logic language that allows to manage uncertain and imprecise information in a declarative framework, hence its importance. Similarity-based SLD resolution can...
