D4_baseline

This repository contains the full pipeline to train and evaluate the baseline models in the paper D4: a Chinese Dialogue Dataset for Depression-Diagnosis-Oriented Chat. To get access to D4, please visit the website of D4.

Latest Experiment Results

We split the entire depression diagnosis dialogue procedure into 4 subtasks:

• Response Generation aims to generate doctors' probable responses based on the dialog context;
• Topic Prediction predicts the topic of the response based on the dialogue context.
• Dialogue Summary generates symptom summaries based on the entire dialog history;
• Severity Classification separately predicts the severity of depressive episodes and the suicide risk based on the dialogue context and dialogue summary.

Response Generation and Topic Prediction

In our experiments, we jointly optimize the topic prediction model and the response generation model. We take the topic as a special first token of dialogue response.

− means topics are excluded, BERT means topics predicted by BERT are given as prompt, ∗ means golden topics are given as prompt
