Team ABC @ AutoMin 2021: Generating Readable Minutes with a BART-based Automatic Minuting Approach

This paper documents the approach of our Team ABC for the First Shared Task on Automatic Minuting (AutoMin) at Interspeech 2021. This challenge’s primary task (Task A) was to generate meeting minutes from multi-party meeting proceedings automatically. For this purpose, we develop an automatic minuting pipeline where we leverage a denoising autoencoder for pretraining sequence-to-sequence models and fine-tune it on a large-scale abstractive dialogue summarization dataset to summarize meeting transcripts. Specifically, we use a BART model and train it on the SAMSum dialogue summarization dataset. Our pipeline first splits the given transcript into blocks of smaller conversations, eliminates redundancies with a specially-crafted rule-based algorithm, summarizes the conversation blocks, retrieves the block-wise summaries, cleans, structures, and finally integrates the summaries to produce the meeting minutes. Our proposed system performs the best in several evaluation metrics (automatic, human) in the AutoMin shared task. We use certain text similarity metrics for the subsidiary tasks to determine whether a given transcript-minute pair corresponds to the same meeting (Task B) and if a given pair of meeting minutes belong to the same meeting (Task C). However, our simple machine-learning-based approach did not perform well in addressing the objective of the subsidiary tasks in the challenge. We publicly release our system codes at https://github.com/cruxieu17/automin-2021-submission
