概括

本指南回顾了神经嵌入和量化心理构造的方法. 推使用分布式字典表示来实现跨文本类型的概括性.

科学领域:

计算语言学计算语言学
心理学是一门科学.
自然语言处理自然语言处理.

背景情况:

神经嵌入表示词和概念作为矢量.
量化嵌入式的心理构造带来了方法学上的挑战.
了解嵌入的几何性质对于准确的分析至关重要.

研究的目的:

审查神经嵌入模型并比较量化心理构造的方法.
为神经嵌入的几何性质提供直觉.
突出使用嵌入用于心理学研究的方法问题.

主要方法:

三种方法的比较:分布式字典表示 (词汇列表),上下文化构造表示 (问卷) 和相关性定向量 (标记示例).
分析每个方法在不同文本类型和研究环境中的通用性和适用性.
评估矢量空间几何和相似度量 (共数,点积).

主要成果:

非上下文化的词嵌入可能比上下文化的大型语言模型嵌入更好地在各个类型中进行概括.
分布式字典表示在量化抽象构造以进行跨类分析方面表现出色.
语境化构造表示适用于特定的,内容相似的文本,而相关性定向量则需要大量的标记数据.

结论:

嵌入方法的选择取决于具体的研究问题和数据特征.
分布式字典表示为抽象的,跨类型的心理构造提供了广泛的应用.
仔细考虑方法限制对于使用神经嵌入的有效研究至关重要.

Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...
