This repository contains the YouTube data used in the project CLINT (https://clint-project.github.io/) during the task that developed prediction models for content classification, link generation, and analysis of polarization evolution. Summary This repository contains a labelled dataset derived from the Recfluence project (https://recfluence.net/), where YouTube channels have been annotated according to their political bias (Left / Center / Right) and content type tags, such as Mainstream News or Conspiracy. We focused on two subnetworks with opposing tags: Partisan Network: Videos from channels tagged as either partisan left or partisan right. Content-Type Network: Videos from channels tagged as mainstream news or conspiracy. Data for both networks was collected using the YouTube Data API, following the official documentation and adhering to quota limitations. We queried videos from the available channels related to climate change and labelled each video according to the channel’s evaluation.
