LLM reasoning and evaluation for summarization explored in new arXiv papers

By PulseAugur Editorial · [2 sources] ·

Two new arXiv papers explore the effectiveness of Large Language Models (LLMs) for abstractive summarization. The first paper introduces OmniCSEval, a comprehensive benchmark designed to evaluate LLMs across diverse scenarios, context lengths, and reasoning capabilities, using a novel fact-checking framework. The second paper investigates the impact of reasoning strategies on summarization quality and factual faithfulness, finding that explicit reasoning can sometimes degrade factual grounding and that increasing an LLM's internal reasoning budget does not always improve performance.

    A Large-Scale Multi-Dimensional Empirical Study of LLMs for Conversation Summarization

    arXiv:2606.15974v1 Announce Type: new Abstract: Despite the significant advancement of LLMs in conversation summarization, their evaluation remains limited by insufficient scenarios, input lengths, and sample sizes. Furthermore, existing benchmarks often omit frontier reasoning s…

    Understanding LLM Reasoning for Abstractive Summarization

    arXiv:2512.03503v3 Announce Type: replace Abstract: Reasoning has substantially improved Large Language Models (LLMs) on analytical tasks such as mathematics and code generation, but its value for abstractive summarization remains unclear. To address this gap, we adapt general re…
