Commands
FCA4J provides the following commands, organized by domain.
Formal concept analysis
lattice
builds a concept lattice. ADD_EXTENT and ADD_INTENT algorithms build the complete concept lattice. ICEBERG builds a latt…
aocposet
build a sub-order of the concept lattice restricted to attribute-concepts and object-concepts
rulebasis
compute the canonical basis of implications (Duquenne-Guigues)
dbasis
compute the ordered direct basis of implications (D-Basis)
clarify
eliminate any duplicated objets (--xo option), attributes (--xa option) or both
reduce
reduce formal context to irreductibles (--xo option), attributes (--xa option) or both
inspect
inspect formal context file and display information about size, density etc.
irreducible
list irreducible objets (-lobj option) or attributes (-lattr option). Use -u option to operate by class on unclarified c…
