Can AI Combat Fake News?May 3, 2020
The phenomena of “fake news” may have captured the imagination of Americans during the 2016 Presidential Campaign and the later investigation of Russia’s attempts to swing the election to Donald Trump using fake news on Facebook among other schemes.
The truth is that fake or phoney news has been around as a tool for a while and by many to spread propaganda and conspiracy theories for many years prior to the 2016 election. Websites including InfoWars and Brietbart among others have been spreading fake news that supports their agendas.
However, it has become a political and societal issue since the election and poor Facebook has become the poster child of websites that fell for the scheme.
Recently the social media company has admitted to its mistakes and has tried to make things right with their subscribers. It is now flagging phoney news articles that are going to Facebook members via their news feed. It is using AI to achieve this.
The company is using AI to identify words or phrases that might signify that an article is actually fake. The data for this task is based on the articles that Facebook members have flagged individually as being bogus stories.
The technology is currently using four methods to spot fake news. They include:
- Score Web Pages. First to use this technique was Google. It uses facts to create a score for websites. Obviously, scoring websites is an act in progress. Yet, as Google has been doing it, the technology has grown significantly.
- Weigh Facts. This method is using natural language processing engines to review the subject matter of stories. AI using other models finds out if other sites are reporting the same facts.
- Predict Reputation. This technique is based on AI using predictive analytics and machine learning to forecast the reputation of websites by considering a number of features including domain name and Alexa web rank.
- Discover Sensational Words. Fake news proponents have used sensational headlines to grab the interest of a potential audience. This technique discovers and flags fake news headlines using keyword analytics.
The actual detection of these types of articles by AI is a difficult endeavor. Of course, the analysis of big data is involved, but it also concerns data veracity. Identifying it is actually involved with determining the truth of the data. This can be done using the method of weighing facts. What happens if a fake news article appears on hundreds of websites at the same time? Under this circumstance, using the technique of weighing facts may cause AI to determine that the story is legitimate. Perhaps using the method of predict reputation in conjunction with weighing facts can help, but there still could be problems. For example, reliable news source websites that don’t take the time to verify a news story could pick it up assuming that it is true.
It’s obvious that using AI to identify these articles needs more development. A number of organizations are involved in enhancing AI’s capability. One such establishment that is involved is West Virginia University.
The Reed College of Media in cooperation with the Benjamin M. Statler College of Engineering and Mineral Resources of West Virginia University has created a course that is focused on using AI to identify phoney news articles.
Senior students taking a computer science elective course are working in teams to develop and implement their own AI programs are also involved in the project.
Another group known as Fake News Challenge is also in pursuit of a way for AI to successfully combat fake news. It is a grassroots organization of more than 100 volunteers and 71 teams from academia and industry to address the problem of fake news. It is developing tools to help people fact check and identify fakes news stories.
As organizations work on enhancing AI to find these stories, there are a variety of tools that are available to strike a blow against them. These include:
- Spike, which identifies and predict breakout and viral stories and uses big data to predict what is going to drive engagement.
- Hoaxy, which is a tool that assists users to identify fake news websites.
- Snoopey, which is a website that helps identify phoney news articles.
- CrowdTangle, which is a tools that helps monitor social content.
- Meedan, which is a tool that helps verify news breaking online.
- Google Trends, which monitors searches.
- La Decodes From Le Monde, which is a database of fake news and real news websites.
- Pheme, which is a tool that verifies the veracity of user-generated and online content.
