The aim of this seminar hosted by the Management and Marketing Group at Essex Business School is to discuss the spread of misinformation surrounding the COVID-19 pandemic. 

Seminar Abstract

Misinformation can amplify humanity's greatest challenges.

A salient recent example of this is the COVID-19 pandemic, which has bred a multitude of falsehoods even as truth has increasingly become a matter of life and death; people share false claims about COVID-19, in part, because they simply fail to think sufficiently about whether or not content is accurate when deciding what to share (Pennycook, et al., 2020). 

Members of the research project (EBS and LAMFO) in partnership with Microsoft (AI for Health) elucidate the context in which the project was conceived and discuss breathy about the motivation and objectives about the topic of disinformation during COVID-19.

Through data e.g. coming from the population (crowdsourcing) it is possible to identify patterns of behaviour that indicate information bubbles and systematic misinformation replication.

Text mining and machine learning techniques are applied in this project to bring insight that can help in this by extracting meaningful information from the huge volume of data that is being generated around the pandemic.


This seminar is free to attend with no need to book in advance. We warmly invite you to share with your friends, colleagues and classmates.

Join us for this event on Zoom.
