Уровень смертности с поправкой на возраст составляет 27,74 на 100 000 населения. Казахстан занимает четвертое место в мире по этому показателю. В этой статье представлено сравнение алгоритмов машинного обучения с учителем и без учителя для выявления депрессивного контента в постах в социальных сетях сакцентом на безнадежность и психологическую боль для семантического анализа в качестве ключевых причин самоубийства. Самоубийство не является спонтанным, и подготовка к самоубийству может длиться около года, в течение которого человек будет демонстрировать признаки своего состояния, в нашем случае, публикуя депрессивный контент в своем профиле в социальной сети. Этот алгоритм помогает в обнаружении депрессивного контента, который может вызвать самоубийство, чтобы помочь людям найти уверенную помощь от психологов национального центра по предотвращению самоубийств в Казахстане. Получив наивысший результат для 95 % оценки f 1 для случайного леса (обучение с учителем) с моделью векторизации tf-idf. В заключение можно сказать, что алгоритм K-means (обучение без учителя) с использованием tf-idf показывает впечатляющие результаты, которые ниже только на 4 % f 1 и точности.</p></abstract><trans-abstract xml:lang="en"><p>According to the latest WHO data published in 2017 Suicide Deaths in Kazakhstan reached 4,855 or 3.55 % of total deaths. The age adjusted Death Rate is 27.74 per 100,000 ofpopulation ranks Kazakhstan #4 in the world. This article shows the comparison of supervised and unsupervised machine learning algorithms, for detecting of depressive content in posts in social networks with emphasis on hopelessness and psych-ache for semantic analysis as the key reasons for suicide. Suicide is not an impulsive act and preparation for suicide can last about a year, during which a person will show signs of his condition in our case posting depressive content on his social network profile. This algorithm helps in detections of depressive content which can cause suicide, to help founded persons reach confident help from psychologists of national suicide preventing center in Kazakhstan. Obtaining highest result for 95 % of f 1-score for Random Forest(supervised) with tf-idf vectorization model, in conclusion of comparison we may say that K-means (Unsupervised) using tf-idf shows impressive results, which is only 4 % lower in f 1-score and precision.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>случайный лес</kwd><kwd>анализ тональности</kwd><kwd>k-средние</kwd><kwd>машинное обучение</kwd><kwd>обучение с учителем</kwd><kwd>обучение без учителя</kwd></kwd-group><kwd-group xml:lang="en"><kwd>random forest</kwd><kwd>sentiment analysis</kwd><kwd>k-means</kwd><kwd>machine learning</kwd><kwd>supervised learning</kwd><kwd>unsupervised learning</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">World Health Organization.
