THE EXTENDED META-LANGUAGE OF NORMAL FORMS OF KNOWLEDGE

Abstract. Two variants of text and graphic descriptions of the meta-language of normal forms of knowledge, extended by the stylistic relations of the information structure descriptions, are presented. The set of the relations of normal forms of knowledge (alternative, concatenation, negation and iteration) is extended by two new relations: commitment relation (non-zero number of repetitions of some structure) and non-commitment relation of some structure, and structure brackets. The descriptions of new relations in text and graphic forms are also presented through the basic relations.

Keywords: meta-language, self-description of the meta-language, self-description graph of the meta-language, commitment relation, non-commitment relation, structure brackets.
