Protoconcept Graphs: The Lattice of Conceptual Contents

Protoconcept graphs are part of Contextual Judgment Logic. Generalizing the well-developed theory of concept graphs, they express judgments with a negation on the level of concepts and relations by representing information given in a power context family in a rhetorically structured way. The conceptual content of a protoconcept graph is understood as the information which is represented in the graph directly, enlarged by the information deducible from it by protoconcept implications of the power context family. The main result of this paper is that conceptual contents of protoconcept graphs of a given power context family can be derived as extents of the so-called conceptual information context of the power context family, thus a generalization of the Basic Theorem on $\overrightarrow{{\mathbb K}}-$Conceptual Contents in [Wi03].
