1. A language teaching process, comprising:

  • initializing a semantic network modeling an interactive story using triples having one object and one relation, two objects and one relation, or one object and two relations, wherein truth values associated with each object and relation are expressed using a four-valued logic system allowing true values, false values, defined values, and undefined values,defining a set of phrasal rewrite rules that accept an input triple as an argument;

    applying a particular phrasal rewrite rule to a particular argument when;

    elements expected to be true by said phrasal rewrite rule are set to true in said argument,elements expected to be false by said phrasal rewrite rule are set to false in said argument, andelements associated with horizontal features are encoded as expected in said argument,substituting syntactic units from said particular phrasal rewrite rule'"'"'s right hand side for its left hand side when said phrasal rewrite rule is applied, inheriting elements of its argument to the syntactic units of the right hand side, and distributing features of inherited arguments from designated syntactic units to other syntactic units on the right hand side;

    generating a sentence in a target language by selecting words from a vocabulary list to express syntactic units generated by applied phrasal rewrite rules; and

    presenting said sentence audibly and/or visually to a user.
