AI总结:

本文提出基于Transformer的模型,在社交媒体文本中检测并解释抑郁症状标记,通过分离或统一分类与解释任务,并探索对话式大语言模型,实现良好分类性能与可解释性并存。

摘要:

社交平台的用户通常将这些网站视为支持性空间,用以发布关于其心理健康问题的内容。这些对话中包含了关于个体健康风险的重要痕迹。近年来,研究人员利用这些在线信息构建心理健康检测模型,旨在识别如Twitter、Reddit或Facebook等平台上的高风险用户。这些模型大多以取得良好的分类结果为中心,忽略了决策的可解释性和可理解性。近期研究指出了使用临床标记(如症状的使用)对于提高医疗专业人员对计算模型信任的重要性。在本文中,我们提出使用基于Transformer的架构来检测并解释用户写作中抑郁症状标记的出现。我们提出了两种方法:i) 训练一个模型进行分类,并单独训练另一个模型来解释分类器的决策;ii) 使用单一模型同时统一这两个任务。此外,对于后一种方式,我们还研究了近期对话式大语言模型在使用上下文学习时的性能。我们的自然语言解释使临床医生能够基于经过验证的症状来解释模型的决策,从而增强对自动化过程的信任。我们使用近期基于症状的数据集评估我们的方法,采用离线指标和专家参与指标来评估我们模型生成的解释质量。实验结果表明,在生成可解释的基于症状的解释的同时,实现良好的分类结果是可能的。

英文摘要:

Users of social platforms often perceive these sites as supportive spaces to post about their mental health issues. Those conversations contain important traces about individuals' health risks. Recently, researchers have exploited this online information to construct mental health detection models, which aim to identify users at risk on platforms like Twitter, Reddit or Facebook. Most of these models are centred on achieving good classification results, ignoring the explainability and interpretability of the decisions. Recent research has pointed out the importance of using clinical markers, such as the use of symptoms, to improve trust in the computational models by health professionals. In this paper, we propose using transformer-based architectures to detect and explain the appearance of depressive symptom markers in the users' writings. We present two approaches: i) train a model to classify, and another one to explain the classifier's decision separately and ii) unify the two tasks simultaneously using a single model. Additionally, for this latter manner, we also investigated the performance of recent conversational LLMs when using in-context learning. Our natural language explanations enable clinicians to interpret the models' decisions based on validated symptoms, enhancing trust in the automated process. We evaluate our approach using recent symptom-based datasets, employing both offline and expert-in-the-loop metrics to assess the quality of the explanations generated by our models. The experimental results show that it is possible to achieve good classification results while generating interpretable symptom-based explanations.
