社会行动者内嵌于各种社会和空间网路中。许多社会和自然系统都呈现出网路结构。社会科学的一个基本问题是，这些网路如何通过限制和提供机会影响内嵌其中的个人。这与社会影响的结构主义研究有关，如网路动员、在线社交网路中的产品和资讯传播等。社会科学的另一个一般性问题是，这些网路如何形成，其功能与结构又如何联系在一起。这与社会选择的研究有关，如友谊的形成和政治区隔等。

大流行中使用韩国 GPS 导航数据研究移动网路中小世界结构的可持续性

This project uses large-scale mobility data that have recorded all the travels with the use of a GPS navigation service in Jeju-do (the largest island in South Korea) during the entire period of COVID-19 from 2019 to present. This dataset includes spatial information, users’ demographic attributes, and the specific activity classification of travelers’ destinations. The main analytical task is to map such mobility data into a multi-layer network. The goal of our analysis is to ascertain (1) whether the mobility network in South Korea’s most popular travel destination reveals a small-world structure and, if so, (2) the degree to which government’s shutdown strategy (a quasi-natural experiment) was able to undermine the prone-to-diffusion structure beyond reducing overall nodal degrees. We also investigate how this structural change varies by types of trip, and whether it is correlated with the trend of the local prevalence of COVID-19. 

合作网络与韩国嘻哈音乐的演变

This project uses a quasi-natural experiment and large-scale web-scraped music data to explain how a music genre as a whole evolves with the collaboration across independent artists and organizations. A particular attention is given to (i) causal inference of the effects of making collaboration ties in consideration of reputation and performance (ii) the differentiation and integration of genre and lyrical styles.
