Ordinally equivalent data: A measurement-theoretic look at formal concept analysis of fuzzy attributes
نویسنده
چکیده
We show that if two fuzzy relations, representing data tables with graded attributes, are ordinally equivalent then their concept lattices with respect to the Gödel operations on chains are (almost) isomorphic and that the assumption of Gödel operations is essential. We argue that measurement-theoretic results like this one are important for pragmatic reasons in relational data modeling and outline issues for future research.

Thresholds and Shifted Attributes in Formal Concept Analysis of Data with Fuzzy Attributes
We focus on two approaches to formal concept analysis (FCA) of data with fuzzy attributes recently proposed in the literature, namely, on the approach via hedges and the approach via thresholds. Both of the approaches present parameterized ways to FCA of data with fuzzy attributes. Our paper shows basic relationships between the two of the approaches. Furthermore, we show that the approaches ca...
متن کاملCrisply Generated Fuzzy Concepts
In formal concept analysis of data with fuzzy attributes, both the extent and the intent of a formal (fuzzy) concept may be fuzzy sets. In this paper we focus on so-called crisply generated formal concepts. A concept 〈A,B〉 ∈ B (X,Y, I) is crisply generated if A = D↓ (and so B = D↓↑) for some crisp (i.e., ordinary) set D ⊆ Y of attributes (generator). Considering only crisply generated concepts ...
متن کاملACL-Scale as a Tool for Preprocessing of Many-Valued Contexts
One of the formal technique in Data mining is Formal Concept Analysis (FCA). During preprocessing of a many-valued context many applications of FCA require the partitioning of numerical data attributes into some smaller intervals. Designation of such numerical intervals with linguistic terms without domain experts will help researchers to understand attributes and their dependencies better. To ...
متن کاملReducing the size of fuzzy concept lattices by fuzzy closure operators
The paper presents a general method of imposing constraints in formal concept analysis of tabular data with fuzzy attributes. The constraints represent a user-defined requirements which are supplied along with the input data table. The main effect is to filter-out conceptual clusters (outputs of the analysis) which are not compatible with the constraint, in a computationally efficient way. Our ...
متن کاملRelational Data, Formal Concept Analysis, and Graded Attributes
Formal concept analysis is a particular method of analysis of relational data. In addition to tools for data analysis, formal concept analysis provides elaborated mathematical foundations for relational data. In the course of the last decade, several attempts appeared to extend formal concept analysis to data with graded (fuzzy) attributes. Among these attempts, an approach based on residuated ...
