Compliance with the European Union's Platform-to-Business (P2B) Regulation is
challenging for online platforms, and assessing their compliance can be
difficult for public authorities. This is partly due to the lack of automated
tools for assessing the information (e.g., software documentation) platforms
provide concerning ranking transparency. Our study tackles this issue in two
ways. First, we empirically evaluate the compliance of six major platforms
(Amazon, Bing, Booking, Google, Tripadvisor, and Yahoo), revealing substantial
differences in their documentation. Second, we introduce and test automated
compliance assessment tools based on ChatGPT and information retrieval
technology. These tools are evaluated against human judgments, showing
promising results as reliable proxies for compliance assessments. Our findings
could help enhance regulatory compliance and align with the United Nations
Sustainable Development Goal 10.3, which seeks to reduce inequality, including
business disparities, on these platforms.

我们的研究通过对六大主要平台（Amazon、Bing、Booking、Google、Tripadvisor 和 Yahoo）的检测，评估了欧盟平台对企业（P2B）规例的合规性，并引入和测试了基于 ChatGPT 和信息检索技术的自动合规评估工具，其可作为可靠的合规性评估代理。我们的研究结果有助于提高规章合规性，并与联合国可持续发展目标 10.3 保持一致，该目标旨在减少这些平台上的不平等，包括商业差距。
