Abstract
It is commonly believed that "intelligent" manipulation of natural language (NL) requires the translation of texts into some internal form (e.g., deep structure). However, many disadvantages also arise from the use of internal forms. In order to avoid most of them, reasoning directly on texts should be considered. But this alternative has its own drawbacks and is not generally taken seriously since it entails a dramatic increase in the already “explosive” nature of the process. We discuss here a pattern-matching technique and a strategy, called caricature, that are shown to counteract the effect of this explosion, and we give some results and prospects.
