DxHF decomposes long responses into decomposed claims, links similar statements, encodes claim relevance, and keeps raw text visible; an LLM-driven workflow performs decomposition, ranking, and linking. A crowdsourcing study (N=160) reports a 5% accuracy gain on preference labels and an average 18s slower judgment time, with the biggest improvement when annotator certainty is low. Simulated annotators show decomposition helps under low rationality; the UI reduces cognitive load but may introduce decomposition-induced bias.
