Practical Solutions for Long-Context LLMs

Addressing Citation Precision

Large language models (LLMs) are essential for tasks like question-answering and text summarization. However, ensuring their reliability and accuracy is crucial. Many models suffer from “hallucination,” generating unsupported information, affecting user trust. The inability to provide fine-grained citations linked to specific text parts also poses a challenge.

CoF System for Improved Citation Accuracy

The CoF (Coarse to Fine) system offers a solution by generating highly detailed, sentence-level citations, enhancing the precision and usability of LLM-generated answers. This approach provides users with citations linked to specific sentences, addressing the problem of broad, imprecise citations.

Research Findings and Performance

Research demonstrates that CoF-trained models outperform existing proprietary models in terms of citation quality and granularity. These models achieved significant improvements in citation accuracy, with notably shorter average citation lengths, reducing the occurrence of hallucinations and ensuring more grounded responses.

Advancement in Long-Context LLMs

This research represents a significant step forward in improving the trustworthiness and verifiability of LLM-generated responses. By focusing on sentence-level citations rather than broad text chunks, the CoF system enhances the performance of long-context QA systems, making LLMs more dependable tools for information retrieval and question-answering tasks.
