People who easily receive hoax news from information that is disseminated instantly change their mindset and emotional feelings towards the contents of news that contain hate speech. The government is trying to prevent and oversee every hoax news disseminator, and will even give penalties to hoax spreaders. The reason is that hoax news only harms and gives a bad reputation to others for the delivery of incorrect information. To prevent this, a grouping of data is made to detect the level of accuracy of the news disseminated by the Naive Bayes classifier method in Android-based. This method was chosen in addition to new developments in spam filtering programming, it also has a higher level of accuracy.
