St. Pölten UAS Graduate Develops Fake News Detector

Detecting Fake News Automatically

ST. PÖLTEN, Austria, March 2, 2021 /PRNewswire/ -- Armin Kirchknopf, a graduate of the degree programme Interactive Technologies at the St. Pölten University of Applied Sciences, Austria, has developed an automatic detector for fake news within the framework of his thesis and a research project. The programme uses artificial intelligence techniques to classify messages by evaluating texts, images and other information from social media.

On the internet and on social media, it is often difficult to tell the difference between fake news and real news. In his master thesis, Armin Kirchknopf, graduate of the St. Pölten UAS and research assistant in the research group Media Computing, developed methods that allow for the automatic detection of potential fake news — at least in a first step.

Many Aspects and the Context Are Decisive

There have already been attempts to do so, but existing methods mostly focused on a specific type of data (e.g. text) and a limited amount of datasets. Kirchknopf's Fake News Detector combines a variety of information, such as text, images and comments.

He also uses other so-called meta information from social media. This includes information on the users' verification status, approving or dismissive reviews of a post, the number of comments it received, and whether it was shared. Based on a dataset of more than 1 million entries from the platform reddit.com, Kirchknopf developed an automatic method for detecting potential fake messages. In principle, the detector could also be used for other platforms if adjusted accordingly.

Kirchknopf built his Fake News Detector based on neural network models from the field of artificial intelligence, and on methods of natural language processing (NLP) and computer vision. The aim was to develop a system capable of learning that adapts to new topics and uses metadata from social media to improve the recognition of fake news.

Human Intellect Cannot be Replaced

The aim of Kirchknopf's work was to create a method that would enable users of social media channels to quickly identify news as fake or true.

"It isn't all about true or false. Fake news is not just a matter of black or white. The programme is designed to provide a context to quickly classify content. Often, the only classification is 'likely fake'. To go into depth, more research and further large datasets are needed. In the end, common sense, which can only be provided by human intellect, is still decisive," says Kirchknopf.
