Collaborative Research: EAGER: Cross-platform Election Advertising Transparency Initiative

点击翻译按钮获取中文摘要

Nearly $2 billion was spent on digital advertising in the presidential general election in 2020, and online advertising is only expected to grow. Campaigns’ rapid shift to digital, however, has caused headaches for those who track political advertising. The data provided by online platforms, such as Facebook and Google, come in different formats, contain different collections that are not immediately comparable, and lack metadata necessary to find all ads related to a specific campaign for office, all ads featuring a specific candidate, or all ads within either set that discuss a specific issue. The sheer volume of content requires the use of computational methods to extract the information necessary to answer even basic descriptive questions such as how much money was spent online in a particular race or across all federal races. This project provides the infrastructure necessary to answer critical questions about the role of digital advertising in American democracy, including the extent to which “dark money” dominates campaigns, and the spread and reach of misinformation in campaigns.The project team is building expandable infrastructure to acquire, process, integrate, label, and distribute digital election advertising data from two large online platforms. The result is a centralized repository that provides robust documentation of all procedures and code such that they can be modified to apply to other platforms and contexts for expansion. Cross-platform integration and standardization of digital election advertising data through human and state-of-the-art computational methods reduces costs to individual researchers, provides parallel procedures already in place for analyzing TV advertising (and thus maximizing comparability to existing data), provides linkage information to other data sources, and produces accessible data to benefit the community. Accomplishing this aim is a high risk-high reward endeavor. For instance, new approaches or methods are needed to capture and label relevant advertising by focus, especially when the true sponsor is unclear or disguised.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
