About this paper

Ethan Lin, Zhiyuan Peng, Yi Fang

Researchers from Santa Clara University introduce `SchNovel`, a benchmark for evaluating Large Language Models' ability to assess scholarly novelty within publications, and propose `RAG-Novelty`, a method that integrates retrieval-augmented generation to enhance this capability. Their evaluation shows `RAG-Novelty` improves accuracy over baselines, while also revealing LLMs' susceptibility to biases like prompt order and institutional affiliation when assessing novelty.

Key insights

  • Scholarly novelty assessment requires dynamic access to evolving knowledge, making retrieval-augmented generation (RAG) crucial for LLMs.
  • LLMs exhibit significant biases (e.g., position bias, affiliation bias) when evaluating scholarly novelty, which can impact fairness in automated academic processes.
  • The inherent complexity of a research field and the temporal gap between papers significantly influence LLM performance in novelty assessment.
