This is Jianfeng He's intern project related to Semi-Supervised Dialogue Abstractive Summarization via Selecting High-Quality Pseudolabels using SiCF Scores.

Semi-supervised dialogue summarization (SSDS) leverages model-generated summaries to reduce reliance on human-labeled data and improve the performance of summarization models. While addressing label noise, previous works on semi-supervised learning primarily focus on natural language understanding tasks, assuming each sample has a unique label. However, these methods are not directly applicable to SSDS, as it is a generative task, and each dialogue can be summarized in different ways. In this work, we propose a novel scoring approach, SiCF, which encapsulates three primary dimensions of summarization model quality: Semantic invariance (indicative of model confidence), Coverage (factual recall), and Faithfulness (factual precision). Using the SiCF score, we select unlabeled dialogues with high-quality generated summaries to train summarization models. Comprehensive experiments on three public datasets demonstrate the effectiveness of SiCF scores in uncertainty estimation and semi-supervised learning for dialogue summarization tasks.

conda env create -f dialogue0_v2.yaml

conda activate dialogue0

Then, only ./sicf_example.py/ and ./clean_SiCF/ are related. And you can get the usage of our SiCF score via running

python sicf_example.py

The parameter introductions are detailed in the ./sicf_example.py/ as well.

Then, please move to ./SSDS/ folder for a more detailed README introduction.
