概括
本研究介绍了第一个西班牙和德国自然语言处理 (NLP) 的希望语音数据集. 单语言变压器模型在检测各种类别的希望方面明显优于多语言模型.
科学领域:
- 计算社会科学 计算社会科学
- 自然语言处理 (NLP) 是一种自然语言处理.
- 情感计算是一种情感计算.
背景情况:
- 希望对心理健康至关重要,但它的语言表达在NLP中没有得到充分的研究.
- 现有的数据集和希望语音检测方法是有限的,特别是跨多种语言.
- 这项研究通过专注于西班牙语和德语中对希望的细微检测来弥补这一差距.
研究的目的:
- 介绍MIND-HOPE,这是第一个多类希望语音检测数据集,用于西班牙语和德语.
- 为了比较传统,深度学习和基于变压器的希望检测模型的性能.
- 建立跨语言情感计算和情感分析未来研究的基准.
主要方法:
- 为西班牙语 (19,183条推文) 和德语 (21,043条推文) 创建和注释两个大型基于Twitter的数据集 (MIND-HOPE).
- 将推文分类为通用希望,现实的希望,不现实的希望和不希望.
- 使用5倍交叉验证对机器学习,深度学习和变压器模型进行比较评估.
主要成果:
- 单语言变压器模型 (例如,bert-base-德语-dbmdz-uncased,bert-base-西班牙语-wwm-uncased) 实现了卓越的性能.

Language and Cognition
444
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Stereotype Content Model
14.9K
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...

Stereotype Threat and Self-fulfilling Prophecies
38.8K
When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Empathy
9.7K
Some researchers suggest that altruism operates on empathy. Empathy is the capacity to understand another person’s perspective, to feel what he or she feels. An empathetic person makes an emotional connection with others and feels compelled to help (Batson, 1991). Empathy can be expressed in several ways, including cognitive, affective, and motor.

Ethnic Identity within a Larger Culture

Adolescents from ethnic minority backgrounds face a multifaceted journey in forming their identities, shaped by the intersections of cultural expectations and personal exploration. For these adolescents, identity formation involves not only typical developmental challenges but also navigating the perceptions and attitudes of the majority culture. As they grow, adolescents in ethnic minority groups often become increasingly aware of stereotypes, social biases, and discrimination, all of which...

Self-Evaluation: Self-Enhancement and Self-Verification
5.3K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
