How to introduce negations for formal (semi-)concepts of formal contexts was shown in "Boolean Concept Logic" [Wi00a]. For formal judgments, which are represented by concept graphs of power context families, there is the problem that the negation of a judgment is no more a judgment since judgments are understood as valid propositions. This problem is solved in "Boolean Judgment Logic" by introducing the "negating inversion". This leads to basic algebras of (semi-)concept graphs of power context families which are investigated in this paper to obtain a mathematical foundation of Boolean Judgment Logic. The basic notions and relationships are illustrated by an example concerned with an information system for supporting the configuration of PCs.
