对比维基与Grokipedia政治倾向，发现两者均偏左，但后者右倾内容更突出。
Is Grokipedia Right-Leaning? Comparing Political Framing in Wikipedia and Grokipedia on Controversial Topics
- 通过语义框架和内容优先级比较两平台
- 争议话题下两者差异更大，且均偏左
- 适合关注信息偏见与AI生成内容的读者
在线百科是当代信息基础设施的核心，也成了意识形态偏见争论的焦点。维基百科长期被指偏左，而xAI推出的AI生成百科Grokipedia则被视为右倾替代。本文对二者在具有政治争议的话题上进行对比分析，考察语义框架、政治倾向和内容优先级的差异。结果表明，两平台在文章各部分的语义相似性随章节递减，争议话题下的分歧明显大于随机话题。此外，尽管两者均主要呈现左倾框架，但Grokipedia表现出更明显的双峰分布，右倾内容显著增多。实验代码已公开。
原文摘要 · Abstract (English)
Online encyclopedias are central to contemporary information infrastructures and have become focal points of debates over ideological bias. Wikipedia, in particular, has long been accused of left-leaning bias, while Grokipedia, an AI-generated encyclopedia launched by xAI, has been framed as a right-leaning alternative. This paper presents a comparative analysis of Wikipedia and Grokipedia on well-established politically contested topics. Specifically, we examine differences in semantic framing, political orientation, and content prioritization. We find that semantic similarity between the two platforms decays across article sections and diverges more strongly on controversial topics than on randomly sampled ones. Additionally, we show that both encyclopedias predominantly exhibit left-leaning framings, although Grokipedia exhibits a more bimodal distribution with increased prominence of right-leaning content. The experimental code is publicly available.
