This study plans to investigate online political polarization by analyzing social media data and conducting online experiments. The results of study will explain how exposure to information can affect the formation of opinions and provide a more comprehensive understanding of political polarization.

| Outline of Annual Research Achievements |
My research investigates affective polarization by focusing on the expressed hostility in cross-cutting interactions. Affective polarization is rooted in social group identity theory, which suggests that group membership can trigger more positive emotional reactions toward the ingroup than the outgroup and a greater willingness to cooperate with members of the ingroup. Taking such ingroup favoritism and outgroup animosity into consideration can offer a more complete picture of political polarization. I employ NLP techniques to detect the expressed sentiment and opinion in the tweet content of interactions, then measure affective polarization by examining how expressed sentiments and opinions vary between in-group interaction and cross-cutting interaction.
