The present invention discloses a description and practice method for inferable and precise
semantics based on a
knowledge graph, which relates to the field of intelligent education technology. In the present invention, a
cell description language for the mathematics subject is defined to describe the
semantics of questions, and a complete description framework for concepts, individuals, and relationships is defined, which not only includes common binary relationships but also extends to the description of multi - element relationships. At the same time, for multi - element relationships, corresponding Atom extension rules are defined to obtain all atomic information from simple relationship descriptions, providing a basis for knowledge reasoning, eliminating the diversity and
ambiguity of
natural language, and giving definitions with uniqueness and accuracy. In addition, aiming at the problem of non - uniqueness of
semantic information, the normalization rules of the
cell language are defined to eliminate
ambiguity, solving the problem that the existing methods cannot accurately and unambiguously describe the
semantics of questions. On this basis, the present invention can realize the intelligent solution of questions through an
inference engine, greatly reducing the teaching cost and tutoring cost of teachers.
