如何与明星结婚:语境中意义的概率约束
How to marry a star: probabilistic constraints for meaning in context
摘要:
在本文中,我们推导出一个概念的“语境中的词义”,其特点是内涵和概念的意义。我们介绍了一个框架,指定本地以及全球的限制,在上下文中的词义,连同它们的相互作用,从而模拟广泛的词汇变化和歧义观察到的话语解释。我们把句子的意义表示为一个“情景描述系统”,一个概率模型,它把话语理解看作是一个向自己描述一个或多个情景的心理过程,这些情景将解释所观察到的话语。我们展示了如何在实践中实现该系统,并将其应用到包含各种情境化现象的例子。
英文摘要:
In this paper, we derive a notion of 'word meaning in context' that characterizes meaning as both intensional and conceptual. We introduce a framework for specifying local as well as global constraints on word meaning in context, together with their interactions, thus modelling the wide range of lexical shifts and ambiguities observed in utterance interpretation. We represent sentence meaning as a 'situation description system', a probabilistic model which takes utterance understanding to be the mental process of describing to oneself one or more situations that would account for an observed utterance. We show how the system can be implemented in practice, and apply it to examples containing various contextualisation phenomena.
