Notions of Knowledge Structures

Description

Computes notions of knowledge structures.

Arguments

x An R object of class kstructure.

Details

A notion is a set of items always jointly contained in some knowledge states. Consequently, these items carry the same information and may therefore be considered equivalent. A knowledge structure where each notion contains only one item is considered discriminative.
