• Abstract summary: We propose a probing dataset to evaluate LLMs' ability to detect errors in KKE and UKE. The results indicate that even the latest LLMs struggle to effectively detect these two types of errors. We propose an agent-based reasoning method, Self-Recollection and Self-Doubt, to further explore the potential for improving error detection capabilities.

• Abstract: Large language model (LLM) role-playing has gained widespread attention, where the authentic character knowledge is crucial for constructing realistic LLM role-playing agents. However, existing works usually overlook the exploration of LLMs' ability to detect characters' known knowledge errors (KKE) and unknown knowledge errors (UKE) while playing roles, which would lead to low-quality automatic construction of character trainable corpus. In this paper, we propose a probing dataset to evaluate LLMs' ability to detect errors in KKE and UKE. The results indicate that even the latest LLMs struggle to effectively detect these two types of errors, especially when it comes to familiar knowledge. We experimented with various reasoning strategies and propose an agent-based reasoning method, Self-Recollection and Self-Doubt (S2RD), to further explore the potential for improving error detection capabilities. Experiments show that our method effectively improves the LLMs' ability to detect error character knowledge, but it remains an issue that requires ongoing attention.

  Large language models (LLMs) generate content that can undermine trust in online discourse. Current methods often focus on binary classification, failing to address the complexities of real-world scenarios like human-AI collaboration. To move beyond binary classification and address these challenges, we propose a new paradigm for detecting LLM-generated content.

  Large language models (LLMs) often produce errors, including factual inaccuracies, biases, and reasoning failures. Recent studies have demonstrated that LLMs' internal states encode information regarding the truthfulness of their outputs. We show that the internal representations of LLMs encode much more information about truthfulness than previously recognized.

  This paper introduces a systematic evaluation framework to assess Large Language Models in detecting cryptographic misuses. Our in-depth analysis of 11,940 LLM-generated reports highlights that the inherent instabilities in LLMs can lead to over half of the reports being false positives. The optimized approach achieves a remarkable detection rate of nearly 90%, surpassing traditional methods and uncovering previously unknown misuses in established benchmarks.

  Chinese Grammatical Error Correction (CGEC) aims to correct all potential grammatical errors in the input sentences.

We rethink the roles of LLMs in the CGEC task so that they can be better utilized and explored in CGEC.

  Poor self-correction performance stems from LLMs' inability to find logical mistakes, rather than their ability to correct a known mistake. We benchmark several state-of-the-art LLMs on their mistake-finding ability and demonstrate that they generally struggle with the task. We show that it is possible to obtain mistake location information without ground truth labels or in-domain training data.
