- 요약Lexical sentiment analysis has been used to understand what is expressed in natural language, sometimes to better understand the psychological characteristics of an author, or to understand the author's stance towards an object, such as a product, person, or idea. This methodology has also been used to study temporal patterns in the mood of populations, or to understand the general use of language. In general, these applications study changes in the central tendency of the mood of entire populations. However, it is likely that collective moods may be composed of discordant parts. Can we use these sentiment tools to predict and understand health outcomes for both small cohorts and at the level of populations, and does the analysis of the distribution of sentiment reveal distinct components useful for those goals?In this dissertation, I demonstrate how the use of natural language processing and lexical sentiment of social media timelines can be useful in predicting health outcomes for a small cohort of epilepsy patients. I develop a method based on the singular vector decomposition to discern characteristic components of the distributions of collective sentiment, associated with sub-populations and cohorts of interest. I demonstrate that the first singular component represents the base distribution of sentiment due to the frequency of sentimental words in natural language and show how further components can reveal meaningful patterns in sentiment over time. To show the predictive and analytical power of these components, I demonstrate their use in modeling sex searches as a proxy for human reproductive cycles and mortality during the Covid-19 pandemic.
