Software and Machine Learning Algorithms for Automatic Detection of Fake News

Fake news is like wildfire on the Internet and is often shared without thinking, especially on social networks. Fake news is created to incite agitation against an individual or a group of people or provoke a specific reaction.  Its goal is to influence public opinion and manipulate it in the targeted subjects of the day. Fake news or misleading information can be spread through the Internet, especially social media like Twitter or Facebook. What's more, recognizing it can be a difficult task. 

When researchers working on developing an automated learning tool to detect fake news, realized that there was not enough data and better technique to train their algorithms, they did the only rational task: they compiled hundreds of fake news and articles and provided the machine which may be able to identify and separate fake news from correct news and articles.

Software for Automatic Detection of Fake News

You simply can not download the Internet Data, you can only specify an algorithm to determine things because devices require rules and examples. Typically, this type of training is called BuzzFeed Data Set, which is used to train an algorithm to detect spam. Hyperbolic on Facebook, other datasets focus primarily on the training of artificial intelligence, unfortunately, this method only makes ironic detector algorithms. Due to this inconvenience, the researchers at the Fraunhofer Society have developed a system that automatically analyzes social media sites and filters out false news and misleading information. To do this, the tool analyzes metadata and content, classifies using automated learning techniques, and takes advantage of user interaction to improve results as they move.
Here comes the classification tool designed by Fraunhofer Institute for Communication, Information Processing and Ergonomics FKIE, which can automatically analyze social media posts and process large amounts of data. In addition to text processing, the tool also processes metadata in its analysis and visually presents its results.

Prof. Ulrich Schade from Fraunhofer FKIE, whose research team developed the tool, explained its features “Our software focuses on Facebook, Twitter, and other websites. Tweets are those where you find links pointing to web pages that contain genuine fake news. In other words, if you like, social media acts as a trigger. Fake news materials are generally hosted on websites that are designed to mimic the web presence of particular news agencies and can be hard work and tricky task to separate them from the actual sites. They will often be based on official news items, but in which wording has been changed”.

Ulrich Schade and his team members started the process of building libraries made from serious newspapers and also texts that users can easily identify as fake news. They create a set of learning used to train the system. To filter counterfeit news, researchers use machine learning techniques that automatically search specific markers in metadata and texts. For example, in a political context, it may be the combination or formulations of words that are rarely done in everyday language or journalistic reporting. This is especially common when writers of fake news were writing in a language other than their native language. In such cases, false punctuation, spelling, verb form or sentence structure are warning of all possible fake news items. Other indicators may include cumbersome totals or out-of-place expressions.

“When we work on the system to supply an array of markers, the device will teach itself to select the markers working. Other decisive factors in choosing machine learning approaches are somewhat better that may provide the best results. This is a very time-consuming process because you have to run different algorithms with various combinations of markers,” said Ulrich Schade.

Metadata yields vital clues

Metadata is also used as a marker. In fact, it plays an important role in distinguishing between authentic sources of information and fake news: for example, how often posts are being issued, when a tweet has been determined, and at what time? The timing of a post can tell a lot. For example, it could reveal the origin of the news and the time zone of the country. The high send frequency tells bots to crawl, that increases the probability of a piece of fake news to spread. For example, social bots send their links to a large number of users, so that uncertainty among the public can spread. One can also prove fertile ground for connections of account and follower analysts.
This is because it allows researchers to design graphs of sending data and heat maps, send data and frequency to follower networks. Their individual nodes and network structures can be used to calculate which nodes in the network started a fake news campaign or circulated an item of fake news.

Another feature of the tool and automatic equipment is the ability to detect hate speech. Posts that appear in the form of news, but it also contains hate speech which is often associated with fake news. "The important thing is to develop markers capable of identifying clear cases of hate speech. Examples include expressions like ‘nigger’ or 'political scum'. Researchers are able to adapt their system to different types of text to classify them. Both businesses and public bodies may use the tool in order to identify and combat misleading information and fake news. The software developed by Fraunhofer FKIE can be personal and trained in accordance with any customer's requirements. For public bodies, this can be a useful initial warning system.
