The machine learning model determines Covid-19 fake news

A new machine learning program accurately identifies hypotheses related to Covid-19 on social media.

The change in the importance of words over time for social media posts. The program will then model how they evolve over time. This new tool is expected to help the medical industry combat misinformation online. “A lot of machine learning studies involve misinformation,” said Courtney Shelley, a postdoctoral fellow with the Modeling and Information Systems Group at the Los Alamos National Laboratory, and co-author of the study. Social media focuses on identifying different types of conspiracy theories. Instead, we want to create a more cohesive understanding of how misinformation changes as it is spread. People tend to believe the first message they get, the expert explains. So in the future, the health sector can keep track of which theories are attracting attention on social media. From there, help the health sector create real information, prevent the public from “accepting” fake news. Under the title “Thought I want to share first”, the study used anonymous Twitter data to describe four Covid-19 related topics. Using the collected data for each topic, the team built random machine learning models or artificial intelligence (AI). Then help classify whether that information is wrong or not. “This allows us to observe how individuals talk about this information on social media and see changes over time,” says co-author Dax Gerts. Research shows that posts that contain misinformation carry more negative emotions than usual. At the same time, these fake news tend to develop over time. Because, they are “augmented” details from other topics as well as events in the real world. Furthermore, the study found that surveillance machine learning could be used to automatically identify conspiracy theories. In addition, the unsupervised learning method can be used within each topic, to uncover changes in the importance of words. “It is important for health officials to know how conspiracy theories are evolving and attracting over time. If not, they run the risk of unintentionally making fake news publicly. So it’s important to know how conspiracy theories are changing and how they can incorporate other theories or real-world facts. As a result, helping to strategize coping with factual disclosure campaigns, ”said researcher Courtney Shelley.
