Group chat analysis of hoax detection during the covid-19 pandemic using the k nearest neighbors algorithm and massive text processing
Authors: Umam K
Published: June 2021

Group chat is the most widely used choice of various short information. Besides being easy to send messages, sharing short messages in group chat is considered effective compared to sending massively to several users. The ease of sending short messages in group chat is often used as the spread of fake news and untrue news or hoaxes, especially during the Covid-19 pandemic, the information shared can be easily shared by anyone without seeing a valid source. The dissemination of information related to Covid-19 without a clear source is a dangerous act, because it can lead users into false information and endanger themselves. Fake message detectors have not been widely implemented in instant message applications, for this reason, there is a need for a detector and a machine to analyze activities in group chat and see whether the message is included in content containing fake news or not. If a group chat has a lot of fake news, you can be sure that the group chat is not good to follow. The use of the K-Nearest Neighbors algorithm is considered quite effective in classifying an object, the results can be determined whether it is included in fake news, miss-information news, or true news. The process of processing messages is carried out by the massive text processing method because the characteristics of the text are different for each user so that text processing can be maximized for later classification. As a result, group chat can be analyzed based on active time, user messages, user activity, and messages sent between users.

Comprehending the problem-solving process is an effort that is no less important than teaching problem-solving skills at school. By understanding the problem-solving process, it will be easier to teach at school. Several neurological studies discuss activities in solving problems, but the scope of the discussion is narrow and in-depth. On the other hand, it requires complete information about how the problem-solving process is a complex cognitive process. This research is a systematic literature review using the PRISMA approach. The result shows that the problem-solving skills were developing based on ages of development. The effectiveness of problem-solving skills is characterized by minimal brain activity but produces the right solution. In addition, the result of the review shows that semantic ability and mathematical logic ability play an important role in a problem solving process. Getting complete problem solving process needs many parts of the brain. DLPFC and IFG are the dominant parts of the brain in the process of solving problems.
