System for Monitoring of the Psychological State is Created at MAI
Artemiy Mazaev and Leonid Tsyplenkov, students of Moscow Aviation Institute, developed a way to identify psychological disorders in schoolchildren and students by monitoring their activity on social networks. The system was called "Elisa".The system involves several neural networks. "Elisa" analyzes text posts, photos and videos, and then formulates a forecast. "For analysis, the Latent Dirichlet allocation (LDA) and BigARTM algorithm are used, which analyzes the context and, finding a certain set of words next to it, makes a proposal about what is discussed in the text.For example, the word “kill” can be either positive or negative. And according to statistics, most students in grades 4–9 who have inflicted physical harm on themselves or others left a digital mark on the network — posts, photos, and videos of a dangerous nature.The creators of "Elisa" ran the texts of thousands of posts through semantic analysis, revealing individual words inherent in certain moods of a person. Mental disorder can be recognized in four classes: depression, suicidal thoughts, social phobia, emotional disorder. Objects depicted in visual content (photos and videos) are recognized using the NasNet neural network. The main trigger is a large number of scenes of violence using weapons.Currently, the authors of the program analyze the results of social networks' monitoring obtained with the help of LDA and BigARTM, together with psychologists. The specialists study the groups, to which the user belong, and the content of their posts, after which they make an assumption that he has a specific mental deviation, which should be paid attention to. This process is called "marking". Based on the data received from experts, the BERT neural network is trained.“There is an opinion that representatives of special services analyze the behavior of people by their activity on social networks. There is no substantiated evidence for this. It can only be argued that phones and laptops really have the ability to “peep” and “eavesdrop”. But mainly marketers use it. There is no effective system for monitoring psychological disorders, manifestations of extremism and terrorism in the youth environment,” says Artemy Mazaev.
