The Persistence and Resilience of Misinformation in the Face of Fact Checking (Mistral AI)
The project utilizes a dataset comprising 38,099 links to stories shared on Facebook from 2017 to 2022. These stories were flagged as problematic by Meta's third-party fact-checkers. The primary objective is to identify and analyze emergent narratives, with a focus on examining their persistence and resilience over time and across various platforms. 2. Research Questions How to characterize the impacts of misinformation online? Does misinformation persist (on a story or narrative level) despite fact-checking and debunking efforts? How does misinformation adapt to fact checking? 3. Methodology To identify the topics, we employed LLMs at three distinct levels. Firstly, we used OpenAI's GPT-3.5-turbo-1106 to translate the titles and descriptions of all stories in English. These translated texts were then used to generate embeddings via the Mistral AI API. We clustered these embeddings into 87 distinct groups or topics using the k-means algorithm, based on their proximity. For the final step, we utilized GPT-4-1106-preview to label our clusters. The quality of these labels was assessed in the project's initial phase. Three separate groups of participants independently evaluated the accuracy of the labels, using a five-level scale ranging from “Very Accurate” to “Not Accurate at All”. This evaluation was conducted on a stratified sample of 400 stories. In the final stage, we mapped the stories onto a two-dimensional space. Each group then selected a subset of coherent topics for more in-depth analysis.
