Identifying Social Media Language Impacting Subjective Well-being – An Analysis Using Public Posts Collected from X

This research aims to identify the language features that impact the related variables linked to subjective well-being such as the amount of support received and tendency to depression using the public posts collected on X during the COVID-19 period from May 2020 to May 2022. Given that variables reflecting mental health status are multifaceted, this research aims to identify language features that may indicate these variables as well. By doing so, we hope to understand how specific words can reflect mental health status in a more comprehensive manner

University Students’ Temporal Trends on X and Their Effects on Subjective Well-being during the COVID-19 Pandemic: Examination from a Two-Year Study of Posts

Utilizing natural language processing (NLP) techniques, we extracted nouns from Japanese posts (formerly known as tweets) as language features. These features were then used in regression analyses to link with subjective well-being scores and time-specific study phases, followed by visualization through a new word cloud technique, which can show the time-specific trend in words that are associated with subjective well-being. Check out the full paper (in Japanese) link for details.
