Abstract: The content shared on social media is among the largest data sets on human behavior inhistory. We leverage this data stream to unobtrusively measure the mentaland physical health and well-being of individuals and populations using machine learning and Natural Language Processing (NLP). For depression, machine learning models applied to patients' Facebook statuses can predict their future depression status before it appears in their medical records. For heart disease, the leading cause of death, prediction models derivedfrom geo-tagged Tweets can estimate county mortality rates better than traditional health risk factors. For well-being, Twitter can be used to estimate the subjective well-being of nations while controlling for sampling biases, with resolution unmatched by any other method. In emerging work,Johannes explores the use of Large Language Models to promote well-being and mental health, and highlights some of the many psychological and social impacts LLMs will have on society.
