本文讨论了本体知识与自然语言理解之间的关系。更具体地说，我将考虑本体论领域的知识和词汇意义的知识如何在语言表达的解释中一起工作。一个基本的假设是，根据本体论的区别，语言表达可以分为各种语义类型。本文的具体目的是探讨在这种情况下如何处理复杂的系统歧义问题。这里的术语“系统歧义”代表这样一种现象，即一个词或一个短语有几个可能的含义，这些含义系统地相互关联，并且可以根据使用的语言和非语言背景从中选择合适的含义。考虑到许多表语表达式对它们的论元施加了某些排序选择限制。我将讨论这样一种现象，即在某些情况下，一个词或一个短语在系统上是模糊的，它使自己适应于与之结合的表达的语义格式。这样一种修改消除了一个词或短语的一个或多个可能的含义，实际上是一种语义上的强制。我将主张一种方法，考虑到一组语义强制操作，以满足排序约束。此外，我将说明在语言理解中进行的这种分类推理是如何得到世界知识的认可的。(C)1995年学术出版社
This paper is concerned with some aspects of the relationship between ontological knowledge and natural language understanding. More specifically, I will consider how knowledge of ontological domains and knowledge of lexical meaning work together in the interpretation of linguistic expressions. An essential assumption is that in accordance with ontological distinctions there are various semantic sorts which linguistic expressions can be divided. The specific purpose of the paper is to explore how under these conditions the intricate problem of systematic ambiguity can be dealt with. Here the term ''systematic ambiguity'' stands for the phenomenon that a word or a phrase has several possible meanings which systematically related to one another and from which a suitable meaning can be selected dependently on the linguistic and non-linguistic context of use. Taking into consideration that many predicative expressions impose on their arguments certain sortal selection restrictions. I will deal with the phenomenon that a word or a phrase being systematically ambiguous in some cases adapt itself to the semantic format of the expression it is combined with. Such an adaptation eliminating one or more possible meaning of the word or phrase is in fact a coercion of its semantic sort. I will argue for an approach which takes into account a set of semantic coercion operations to meet sortal constraints. Moreover, I will show how such sort coercions performed in language understanding are sanctioned by world knowledge. (C) 1995 Academic Press Limited
