arXiv:2606.10781v1 Announce Type: cross Abstract: Unsupervised term discovery involves segmenting unlabelled speech into word- or syllable-like units and clustering these into a lexicon of candidate types. True lexicons follow a Zipfian distribution, yet the dominant centre-based clustering approach -- K-means -- produces a more uniform distribution due to an inductive bias toward spherical clusters. In this paper we revisit graph-based clustering as a bottom-up alternative, where segment embeddings are connected by pairwise similarity and partitioned using the Leiden algorithm. We show that g
The increasing sophistication of AI models and the demand for more human-like language processing necessitate improvements in unsupervised term discovery, particularly for resource-poor languages or specialized domains.
Improving the accuracy of unsupervised term discovery, especially by aligning it with natural language distributions like Zipf's Law, directly enhances the foundational capabilities of AI in language understanding and generation.
A shift from biased clustering methods like K-means to graph-based approaches could lead to more robust and accurate lexicons for speech and natural language processing, potentially improving AI model efficiency and performance.

More accurate and comprehensive unsupervised term discovery methods will lead to better performance in various natural language processing tasks.
This could accelerate the development of AI agents capable of understanding and generating human language with greater nuance and efficiency, particularly for new or underrepresented languages.
Improved language understanding could reduce data requirements for training certain AI models, lowering compute costs and democratizing access to advanced NLP technologies.
