From Ambiguity to Accuracy: The Transformative Effect of Coreference Resolution on Retrieval-Augmented Generation systems

Researchers demonstrate that coreference resolution significantly improves Retrieval-Augmented Generation (RAG) systems by reducing ambiguity in document retrieval and enhancing question-answering performance. The study finds that smaller language models benefit more from disambiguation processes, with mean pooling strategies showing superior context capturing after coreference resolution.
