AI总结:

本研究针对传统代词频次统计无法捕捉使用方式的问题,提出用上下文化语言模型的第一人称代词嵌入预测抑郁症状严重程度,经在线心理治疗短信数据验证,效果优于传统方法。

摘要:

既往研究表明,分析第一人称单数代词的使用情况可洞察个体的心理状态,尤其是抑郁症状的严重程度。这些发现是通过统计文本数据中第一人称单数代词的使用频率得出的。然而,频次统计无法捕捉这些代词的具体使用方式。神经语言建模的最新进展已采用生成上下文嵌入的方法。本研究中,我们试图利用从上下文化语言表征模型中获取的第一人称代词嵌入,捕捉这些代词的使用方式,以此分析心理状态。研究采用在线心理治疗期间发送的去标识化短信数据,搭配每周的抑郁严重程度评估结果进行验证。结果显示,在预测抑郁症状严重程度方面,上下文化第一人称代词嵌入的表现优于标准分类词元嵌入和基于频次的代词分析结果。这表明第一人称代词的上下文表征能够提升有抑郁症状人群语言的预测效用。

英文摘要:

Prior work has shown that analyzing the use of first-person singular pronouns can provide insight into individuals' mental status, especially depression symptom severity. These findings were generated by counting frequencies of first-person singular pronouns in text data. However, counting doesn't capture how these pronouns are used. Recent advances in neural language modeling have leveraged methods generating contextual embeddings. In this study, we sought to utilize the embeddings of first-person pronouns obtained from contextualized language representation models to capture ways these pronouns are used, to analyze mental status. De-identified text messages sent during online psychotherapy with weekly assessment of depression severity were used for evaluation. Results indicate the advantage of contextualized first-person pronoun embeddings over standard classification token embeddings and frequency-based pronoun analysis results in predicting depression symptom severity. This suggests contextual representations of first-person pronouns can enhance the predictive utility of language used by people with depression symptoms.
