abstract

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.

CobSeg: Coherence Boundary Modeling for Dialogue Topic Segmentation

cs.CL · 2026-05-29 · unverdicted · novelty 5.0

CobSeg is a multi-branch architecture for dialogue topic segmentation that separates semantic continuity from lexical transitions, uses boundary informativeness weighting and corpus-derived cues, and reports metric gains on five benchmarks under both gold and induced boundary training.
