用AI自动检测并补回简化文本中丢失的关键信息

Automated Feedback Loops to Protect Text Simplification with Generative AI from Information Loss

  • 用GPT-4识别简化文本中缺失的实体和词汇,再回填修复
  • 补全全部缺失实体的重构效果最好,优于仅补排名前3的实体
  • 适合关注健康信息准确传递的研究者与AI内容生成实践者

理解健康信息对维持健康生活至关重要。本文聚焦于利用生成式AI简化健康信息以提升可读性,但现有算法常导致关键信息丢失。研究收集50篇健康文本,使用gpt-4-0613进行简化,并对比五种方法识别缺失元素并重构文本:添加全部缺失实体、添加全部缺失词、添加GPT-4-0613排序前3的实体,以及两种随机添加实体的对照组。通过余弦相似度和ROUGE分数评估原始、简化及重构文本在摘要和全文层面的语义相似性与内容重叠度。结果表明,补全全部缺失实体的方案效果最优,优于仅补前3实体或词语,且当前工具虽能识别缺失项,但无法有效排序。

原文摘要 · Abstract (English)

Understanding health information is essential in achieving and maintaining a healthy life. We focus on simplifying health information for better understanding. With the availability of generative AI, the simplification process has become efficient and of reasonable quality, however, the algorithms remove information that may be crucial for comprehension. In this study, we compare generative AI to detect missing information in simplified text, evaluate its importance, and fix the text with the missing information. We collected 50 health information texts and simplified them using gpt-4-0613. We compare five approaches to identify missing elements and regenerate the text by inserting the missing elements. These five approaches involve adding missing entities and missing words in various ways: 1) adding all the missing entities, 2) adding all missing words, 3) adding the top-3 entities ranked by gpt-4-0613, and 4, 5) serving as controls for comparison, adding randomly chosen entities. We use cosine similarity and ROUGE scores to evaluate the semantic similarity and content overlap between the original, simplified, and reconstructed simplified text. We do this for both summaries and full text. Overall, we find that adding missing entities improves the text. Adding all the missing entities resulted in better text regeneration, which was better than adding the top-ranked entities or words, or random words. Current tools can identify these entities, but are not valuable in ranking them.
