In their paper titled "Trapping LLM Hallucinations Using Tagged Context Prompts," authors Philip Feldman, James R. Foulds, and Shimei Pan address the challenge of hallucinations in large language models (LLMs) such as ChatGPT. While these sophisticated conversation agents have made significant advancements, they often generate false or fabricated information. This issue is particularly crucial as AI-driven platforms are being adopted across various sectors. To tackle this problem, the authors propose a novel method to recognize and flag instances when LLMs perform outside their domain knowledge, ensuring users receive accurate information. They demonstrate that combining context with embedded tags can effectively combat hallucinations within generative language models. The authors establish a baseline for hallucination frequency by examining prompt-response pairs without any context. They use generated URLs as indicators of fabricated data and observe a significant reduction in overall hallucination when context is provided along with question prompts for tested generative engines. Furthermore, the authors evaluate how placing tags within contexts impacts model responses. They achieve an impressive 98.88% effectiveness in eliminating hallucinations in responses by employing this approach. Overall, this research contributes to addressing the limitations of large language models by proposing a method to identify and mitigate hallucinations. By incorporating contextual information and embedded tags, users can be assured of receiving accurate information from AI-driven conversational agents like ChatGPT.

Abstract: Recent advances in large language models (LLMs), such as ChatGPT, have led to highly sophisticated conversation agents. However, these models suffer from "hallucinations," where the model generates false or fabricated information. Addressing this challenge is crucial, particularly with AI-driven platforms being adopted across various sectors. In this paper, we propose a novel method to recognize and flag instances when LLMs perform outside their domain knowledge, and ensuring users receive accurate information. We find that the use of context combined with embedded tags can successfully combat hallucinations within generative language models. To do this, we baseline hallucination frequency in no-context prompt-response pairs using generated URLs as easily-tested indicators of fabricated data. We observed a significant reduction in overall hallucination when context was supplied along with question prompts for tested generative engines. Lastly, we evaluated how placing tags within contexts impacted model responses and were able to eliminate hallucinations in responses with 98.88% effectiveness.
