Reasoning-Based Refinement of Unsupervised Text Clusters with LLMs

Dimensions overall score 7.0

• A reasoning-based framework uses LLMs to refine unsupervised text clusters, improving coherence and interpretability without supervision. We propose a reasoning-based refinement framework that leverages large language models (LLMs) not as embedding generators, but as semantic judges that validate and restructure the outputs of arbitrary unsupervised clustering algorithms.Our framework introduces three reasoning stages: (i) coherence verification, where LLMs assess whether cluster summaries are supported by their member texts; (ii) redundancy adjudication, where candidate clusters are merged or rejected based on semantic overlap; and (iii) label grounding, where clusters are assigned interpretable labels in a fully unsupervised manner.problem 35%

• ScienceToStartup currently rates this 7.0/10 on the public viability pass. Human evaluation shows strong agreement with LLM-generated labels, despite the absence of gold-standard annotations. Code availability is flagged in the production record; the public repository link still needs proof alignment.result 35%
