Formal Concept Analysis
Formal Concept Analysis is a mathematical theory which describes concepts and conceptual hierarchies by means of lattice theory. Thereby, the basis are formal contexts, elementary data structures that describe objects and their attributes. A formal concept is then composed of a set of objects and a set of attributes which -- in line with philosophical and linguistic traditions -- are called concept extent and concept intent, respectively. Formal concepts can then be put into relation to each other, forming a hierarchy of sub- and superconcepts.
Formal Concept Analysis was founded in the 1980s in Darmstadt in the group of Rudolf Wille and has become a discipline with numerous practical applications in diverse areas, including data- and textmining, knowledge management, Semantic Web, software engineering, economics or biology.
