  Topic segmentation of meetings is the task of dividing multi-person meeting
transcripts into topic blocks. Supervised approaches to the problem have proven
intractable due to the difficulties in collecting and accurately annotating
large datasets. In this paper we show how previous unsupervised topic
segmentation methods can be improved using pre-trained neural architectures. We
introduce an unsupervised approach based on BERT embeddings that achieves a
15.5% reduction in error rate over existing unsupervised approaches applied to
two popular datasets for meeting transcripts.
