Data and Concepts Analysis
ABSTRACT
Data analysis methods by formal concept analysis applied mainly for
chemical engineering operations are presented. Entropy calculus is of use
to compare concept lattices trajectories.
Graph spanning is correlated to nesting line diagram and comparison
methods in formal concept analysis.
Keywords: comparison, concept analysis, Galois lattice, graphs spanning,
nested line diagrams, separation schemas, subgraphs
9.1 Formal Concept Analysis
9.1.1 Contexts and Concepts
The formal concept analysis, FCA, is a theory of data analysis which
identifi es conceptual structures among data sets (Ganter and Wille 1999). ...
