A Mathematical Model of the Variety of Natural Language Semantic Structures and Its Significance for Biomedical Sciences

Received on 01.12.2024
Accepted on 20.12.2024

The paper suggests a new interpretation of the three versions of the theory of SK-languages (standard knowledge languages) developed by the author of the present paper in several previous publications. The theory of SK-languages (SKL-theory) is the central constituent of the theory of K-representations (knowledge representations), or TKR, introduced in early 2000s by the author of the paper. The three versions of the SKL-theory are considered as mathematical models of the variety of semantic representations (SRs) of arbitrarily complex sentences and discourses in natural language (NL). The possibilities of interactions of several original expressive mechanisms of the SKL-theory while constructing SRs of the scientific notions' definitions are demonstrated. The broadest prospects of describing semantic structure of sen t ences and discourses in NL pertain i ng to biology and med i cine are i nd i cated. A special attention is paid to explicatin g the advantages of TKR-based approach to building SRs of scientific definitions in comparison with Universal Conceptual Cognitive Annotation, Abstract Meaning Representation, and Uniform Meaning Representation. The second objective of the paper is to demonstrate the possibilities of an original algorithm of semantic parsing of the scientific notions' definitions suggested in one of the previous publications of the author. The output of the algorithm are SRs of the scientific notions' definitions being the expressions of SK-languages.

Keywords: automatic information extraction, natural language processing, semantic parsing of scientific def i nitions, scholarly knowledge, biology, medicine, abstract meaning representation, uniform meaning representation, theory of K-representations, SK-language, conceptual basis
