使用概率模型的语言学家喜欢它们:功能分布语义学中的量化

Linguists Who Use Probabilistic Models Love Them: Quantification in Functional Distributional Semantics

University of Cambridge(剑桥大学)

摘要:

功能分布语义学为从语料库中学习真值条件语义提供了一个计算上易于处理的框架。以前的工作在这个框架中提供了一个概率版本的一阶逻辑,重铸量化贝叶斯推理。在本文中,我将展示如何在使用精确量词和模糊谓词时,前面的公式给出平凡的真值。我提出了一个改进的帐户,避免这个问题,通过治疗一个模糊的谓词作为一个分布在精确的谓词。我把这个帐户最近的工作在理性言语行为框架建模通用量化,我扩展到建模驴句子。最后,我解释了类属量词是如何既实用复杂又比精确量词计算简单的。

英文摘要:

Functional Distributional Semantics provides a computationally tractable framework for learning truth-conditional semantics from a corpus. Previous work in this framework has provided a probabilistic version of first-order logic, recasting quantification as Bayesian inference. In this paper, I show how the previous formulation gives trivial truth values when a precise quantifier is used with vague predicates. I propose an improved account, avoiding this problem by treating a vague predicate as a distribution over precise predicates. I connect this account to recent work in the Rational Speech Acts framework on modelling generic quantification, and I extend this to modelling donkey sentences. Finally, I explain how the generic quantifier can be both pragmatically complex and yet computationally simpler than precise quantifiers.
