SEMANTICS IN LINGUISTIC KNOWLEDGE SYSTEMS
Miroslav Valach · International Journal of General Systems · 1996
This paper looks at the semantics, semantic measures and definitions aimed at the semantics of a Linguistically Represented system of Knowledge (LRK), treated as a semantically closed system. The knowledge is viewed as three complementary subsystems: language of knowledge, knowledge structure, and knowledge operators. The semantics of LRK is contained within the semantic interpretation of the syntactic structures of LRK. To operate and utilize LRK requires that all interfaces, including knowledge itself, be carried out in, and only in, English. The concept of LRK has nothing to do with so-called databases. The concept of a linguistically represented system of knowledge keeps all its content in the form of linguistic structures. LRK systems utilize their own operators for restructuring, extracting, simplification, merging, decomposition, integration, summary and other operations The presented theory examines modifications and substitutions as primary semantic operations. It defines notions, such as, semantic neighborhood, semantic proximity, semantic primitives and semantic units. The theory also introduces several semantic measures. The theory is the basis for the implementation of a knowledge system shell called CORTEXTM, built with the computer language NATLANG, designed for processing English by MARBLE SOFTWARE.
