Formal concept analysis

builds a concept lattice. ADD_EXTENT and ADD_INTENT algorithms build the complete concept lattice. ICEBERG builds a latt…

build a sub-order of the concept lattice restricted to attribute-concepts and object-concepts

compute the canonical basis of implications (Duquenne-Guigues)

compute the ordered direct basis of implications (D-Basis)

eliminate any duplicated objets (--xo option), attributes (--xa option) or both

reduce formal context to irreductibles (--xo option), attributes (--xa option) or both

inspect formal context file and display information about size, density etc.

list irreducible objets (-lobj option) or attributes (-lattr option). Use -u option to operate by class on unclarified c…

to create a conceptual structure family from a relational context family. The output is a JSON file that can be opened i…

Model-driven transformation of multivalued data tables to a Relational Context Family (RCF) file.

transform multivalued data table to formal context

convert formal context file format

to create and manage relational context families (set of formal contexts and relations)
