The Algorithmic Archive project is a one year project funded by the Mellon Foundation. As part of the first Work Package, we explored how researchers from different disciplines use social media data to answer various research questions.
This post is the second in a three-part series presenting use cases drawn from research conducted as part of the Algorithmic Archive project.
We would like to thank the researchers who generously shared insights from their work.
Use Case – Exploring Algorithmic Mediation and Recommendation Systems on YouTube [1]
Research questions and aim(s):
The study sought to investigate how the YouTube platform operates, focusing on algorithmic activity and the strategies employed by both human and automated (robot) actors within federal and regional elections. The aim was to understand the impact that this system of mediation has on society and to demystify preconceptions of ideologically neutral technologies in highly disputed political events. The research focuses on two case studies: 1) the 2018 Ontario (Canada) election and 2) the 2018 Brazilian Federal Election. The data collection was carried out during the campaigning periods, between May and June in Ontario, and between August and October 2018 in Brazil.
Social media data used:
The research focussed on the sole YouTube platform. Specifically, the researchers collected information about recommended videos starting from specific keywords related to the election campaign.
Tools and methods adopted:
The data collection was carried out using a Python script developed by the Algo Transparency project. The script automates YouTube search operations based on specified keywords (e.g., the names of the candidates), allowing the researcher to gather video-related data and the relative ranking position displayed to the user. Once the keywords were defined, the tool retrieved links for the top four results for each keyword and then examined the recommendation section. This process was repeated four times, each time collecting recommended videos, simulating a user interacting with algorithmic suggestions.
Data collected was stored on personal devices and the institutional cloud, and can be visualized at the following links:
