Distributive Concept Exploration - A Knowledge Acquisition Tool in Formal Concept Analysis

摘要

Formal Concept Analysis provides a mathematical model of the concept 'concept' which is used in data analysis for examining conceptual hierarchies in data tables. If these data tables are too large to be completely given, then the conceptual structure has to be determined in an interactive knowledge acquisition process from an expert of the domain. Exploration tools suggest, starting with the concepts to be examined, hierarchical relationships. The expert is asked either to confirm them or to provide typical counter-examples. The result of the exploration is a lattice that is generated by adding all largest common subconcepts and/or least common superconcepts.
