From LLMs to Information Cascades
Invited talk at the École de politique appliquée, Université de Sherbrooke. This presentation covers the pipeline from LLM-based text annotation to media cascade detection, with applications on the Canadian Climate Framing project.
LLM Tool
A local-first, open-source framework for structured text annotation. Five integrated modes, from LLM annotation to BERT training, enabling annotation of millions of sentences with no programming required.
CCF Database
266,000 articles from 20 Canadian newspapers (1978-2024), with 9.2 million sentences annotated across 65 categories. The talk demonstrates a novel method for detecting media information cascades through orthogonalized z-score signals and changepoint detection.
