<p>Simplification of an input sentence into a sentence having a simplicity at a level similar to that of a symbolic logic formula, inference using such a sentence (natural language sentence), and generation of an output sentence on the basis of such a sentence are realized by an adequately simple and integral method. Firstly, inference which has been conventionally made by a symbolic logic scheme is realized by using a natural language sentence having a simplicity at a level similar to that of a symbolic logic formula, thereby unification and simplification of conversion from an input sentence into an output sentence are achieved. Secondary, paraphrase of an input sentence to a sentence at the symbolic logic formula level to an output sentence can be realized by reversely using the paraphrase of the input sentence to a sentence at the symbolic logic formula level. Lastly, since a conditional formula at the symbolic logic formula level can be obtained by similar paraphrase of the original sentence, a general learning scheme can be devised.</p> |
