社交媒体中用于抑郁症检测的深袋子情绪

Deep Bag-of-Sub-Emotions for Depression Detection in Social Media

摘要:

本文介绍了Deep Bag-of-Sub-Emotions(DeepBoSE),这是一种用于社交媒体中抑郁症检测的新型深度学习模型。该模型被公式化,使得它在内部计算包含情感信息的可微分特征袋(BoF)表示。这是通过将词频-逆文档频率等经典加权方案重新解释为概率深度学习操作来实现的。所提出的方法的一个重要优点是,它可以在迁移学习范式下进行训练,这对于增强无法直接集成到深度学习架构中的传统BoF模型非常有用。在eRisk 17和eRisk 18数据集上进行了抑郁检测任务的实验;结果表明,DeepBoSE优于传统的BoF表示,并且与最先进的技术相比具有竞争力,在eRisk 17和eRisk 18中分别获得了0.64和0.65的F1分数。

英文摘要:

This paper presents the Deep Bag-of-Sub-Emotions (DeepBoSE), a novel deep learning model for depression detection in social media. The model is formulated such that it internally computes a differentiable Bag-of-Features (BoF) representation that incorporates emotional information. This is achieved by a reinterpretation of classical weighting schemes like term frequency-inverse document frequency into probabilistic deep learning operations. An important advantage of the proposed method is that it can be trained under the transfer learning paradigm, which is useful to enhance conventional BoF models that cannot be directly integrated into deep learning architectures. Experiments were performed in the eRisk17 and eRisk18 datasets for the depression detection task; results show that DeepBoSE outperforms conventional BoF representations and it is competitive with the state of the art, achieving a F1-score over the positive class of 0.64 in eRisk17 and 0.65 in eRisk18.
