PlagBench: Exploring the Duality of Large Language Models in Plagiarism Generation and Detection (2025.naacl-long)
Copied to clipboard
| Challenge: | Recent studies have raised concerns about the potential threats large language models pose to academic integrity and copyright protection. |
| Approach: | They propose a dataset of 46.5K synthetic text pairs that represent three major types of plagiarism: verbatim copying, paraphrasing, and summarization. |
| Outcome: | The proposed dataset shows that GPT-3.5 Turbo can produce high-quality paraphrases and summaries without significantly increasing text complexity compared to GPT-4 Turbo. |
Can Small Language Models Help Large Language Models Reason Better?: LM-Guided Chain-of-Thought (2024.lrec-main)
Copied to clipboard
| Challenge: | Existing frameworks for guiding a language model in reasoning tasks are limited by their tendency to generate low-quality rationales that are repetitive and vacuous. |
| Approach: | They propose a framework that leverages a lightweight language model for guiding a black-box large LM in reasoning tasks. |
| Outcome: | The proposed framework outperforms baselines in answer prediction accuracy. |
Fighting Fire with Fire: The Dual Role of LLMs in Crafting and Detecting Elusive Disinformation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Recent ubiquity and disruptive impacts of large language models have raised concerns about their potential to be misused. |
| Approach: | They propose a strategy that leverages LLMs' generative and emergent reasoning capabilities to counter human-written and LLM-generated disinformation. |
| Outcome: | The proposed strategy synthesizes authentic and deceptive LLM-generated content through paraphrase-based and perturbation-based prefix-style prompts, respectively. |
Perturbations in the Wild: Leveraging Human-Written Text Perturbations for Realistic Adversarial Attack and Defense (2022.findings-acl)
Copied to clipboard
| Challenge: | ANTHRO extracts over 600K human-written text perturbations and leverages them for realistic adversarial attacks. |
| Approach: | They propose an adversarial text manipulation algorithm that inductively extracts over 600K human-written text perturbations and leverages them for realistic adversarials. |
| Outcome: | The proposed algorithm outperforms the TextBugger baseline with an increase of 50% and 40% in terms of semantic preservation and stealthiness when evaluated by layperson and professional human workers. |

| Challenge: | Existing benchmarks for machine-generated texts (MGTs) include single-author texts (human-written and machine-generated). |
| Approach: | They propose to benchmark machine-generated outputs (Beemo) which includes 6.5k texts written by humans, generated by ten instruction-finetuned LLMs, and edited by experts for various use cases. |
| Outcome: | The proposed benchmark includes 6.5k texts written by humans, generated by ten instruction-finetuned LLMs, and edited by experts for various use cases, ranging from creative writing to summarization. |
