I. Introduction
Fake news in social media is an important problem because it may harm people mentally and physically, especially in the case when fake news is related to health areas. Nowadays when everybody, including children, has easy access to internet sources, and when there is no strict censorship of news and articles and anybody (not only experts or professional journalists) can be a news author, it is very easy to find misinformation in social media, which could lead to serious consequences.
