Sensing Subjective Well-being from Social Media
Subjective Well-being(SWB), which refers to how people experience the quality
of their lives, is of great use to public policy-makers as well as economic,
sociological research, etc. Traditionally, the measurement of SWB relies on
time-consuming and costly self-report questionnaires. Nowadays, people are
motivated to share their experiences and feelings on social media, so we
propose to sense SWB from the vast user generated data on social media. By
utilizing 1785 users' social media data with SWB labels, we train machine
learning models that are able to "sense" individual SWB from users' social
media. Our model, which attains the state-by-art prediction accuracy, can then
be used to identify SWB of large population of social media users in time with
very low cost.Comment: 12 pages, 1 figures, 2 tables, 10th International Conference, AMT

Using Linguistic Features to Estimate Suicide Probability of Chinese Microblog Users
If people with high risk of suicide can be identified through social media
like microblog, it is possible to implement an active intervention system to
save their lives. Based on this motivation, the current study administered the
Suicide Probability Scale(SPS) to 1041 weibo users at Sina Weibo, which is a
leading microblog service provider in China. Two NLP (Natural Language
Processing) methods, the Chinese edition of Linguistic Inquiry and Word Count
(LIWC) lexicon and Latent Dirichlet Allocation (LDA), are used to extract
linguistic features from the Sina Weibo data. We trained predicting models by
machine learning algorithm based on these two types of features, to estimate
suicide probability based on linguistic features. The experiment results
indicate that LDA can find topics that relate to suicide probability, and
improve the performance of prediction. Our study adds value in prediction of
suicidal probability of social network users with their behaviors
Analysis of Users’ Sentiments in Social Media (on the Example of the Astrakhan Region)
The article is devoted to the studying of the opinions and sentiments of users of regional communities in the social network VKontakte using methods of machine analysis of text data, supplemented by sociological research methods. In the course of the study, we identified a list of current topics discussed by the inhabitants of the region, determined the most frequently mentioned persons, and analyzed the tone of their mention. Additionally, on the basis of the obtained results, the index of subjective (non-) well-being (ISW) was calculated for each district of the region and a map of the emotional coloring of posts from the communities of the analyzed social network was built. The results of the study can be used to monitor the situation in the region, finding problem areas, elicitation opinion leaders (popular personalities of the region that have a special influence on the opinion of the population), as well as identify the most interesting topics and urgent problems for the population. In perspective, this method of monitoring the social sentiments of the population of the region can be improved by automating the addition of new data to the analytical project. In the future, the addition of mathematical models to the system will make it possible to create graphs for predicting further changes in the region
Classification community publications of the "VKontakte" for assessing the quality of life of the population
Сегодня социальные сети — это повседневный инструмент пользователя для выражения своих мнений и предпочтений. Цифровые следы, создаваемые в сети, являются ценным источником данных для выделения проблем населения в различных сферах жизнедеятельности. Фокус данной работы сосредоточен на разработке алгоритма, позволяющего автоматически классифицировать текстовый контент социальной сети «ВКонтакте», являющейся одной из популярных платформ среди пользователей, по категориям качества жизни: «образование», «здравоохранение», «безопасность», «социальное обеспечение», «работа органов власти», «экология» и «доступность товаров и услуг». Для реализации поставленной задачи в рамках работы использованы статичные и контекстуализированные модели создания векторных представлений и эффективные алгоритмы классификации русскоязычного контента социальных сетей (LSTM, BiLSTM, GRU, RuBERT). На сегодняшний день мы отдаем предпочтение модели RuBERT-tiny за счет лучших показателей полноты в большинстве категорий
Subjective measurement of population ill-being/well-being in the Russian regions based on social media data
В статье обосновывается новый метод субъективной оценки благополучия, основанный на анализе онлайн-активности пользователей в социальных сетях. Предлагаемый метод обладает как преимуществами (быстрота исследования, небольшие затраты, масштабность, детальность полученной информации), так и определенными ограничениями (охват «цифрового населения», технические сложности при исследовании густонаселенных мегаполисов и т. д.). В статье представлены результаты эмпирического исследования онлайн-активности пользователей социальной сети «ВКонтакте». На основе полученных данных рассчитан индекс субъективного (не)благополучия для 43 регионов РФ по 19 показателям, охватывающих экономические, социальные и политические аспекты качества жизни людей. Индекс субъективного (неблагополучия строится на изучении онлайн-активности пользователей, входящих в 1350 наиболее популярных региональных и городских сообществ в социальной сети «ВКонтакте». Период исследования включает в себя весь 2018 год
Social media mental health analysis framework through applied computational approaches
Studies have shown that mental illness burdens not only public health and productivity but also established market economies throughout the world. However, mental disorders are difficult to diagnose and monitor through traditional methods, which heavily rely on interviews, questionnaires and surveys, resulting in high under-diagnosis and under-treatment rates. The increasing use of online social media, such as Facebook and Twitter, is now a common part of people’s everyday life. The continuous and real-time user-generated content often reflects feelings, opinions, social status and behaviours of individuals, creating an unprecedented wealth of person-specific information. With advances in data science, social media has already been increasingly employed in population health monitoring and more recently mental health applications to understand mental disorders as well as to develop online screening and intervention tools. However, existing research efforts are still in their infancy, primarily aimed at highlighting the potential of employing social media in mental health research. The majority of work is developed on ad hoc datasets and lacks a systematic research pipeline. [Continues.]</div
