Abstract

An informal definition of syntax is given in terms of discrete mathematics and graph theory. The main difficulty for numerous attempts to formalize a natural language is the semantics of the language. It is shown how it is possible to classify expressions on a semantic basis, using their syntactic features. Classification of expressions by the kind of questions they answer is the simplest way of grouping expressions on the semantic basis. The present authors describe an algorithm that recognizes place pointers, that is, expressions which answer the question "where?". On specific examples, the problem of analysis of expressions and the inverse problem of synthesis, more precisely, the applied problem of recognition of expressions are considered.
