In this thesis, we explore relationships between social variables that can be used to assess social events and conditions (social weather). Social weather may have hidden causes, and social events may be related to several variables distributed over diverse data sources. We built an infrastructure integrating data sources using the World Bank, stock market, happiness, terrorism, and Internet usage in the US. We performed data cleaning, data normalization and data aggregation and implemented our data store using Influx DB; we used Grafana for visual exploration of the integrated database.
The integrated data store allowed us to explore data trends and relationships among the social variables. In particular, we explored causal links among large amount of social variables using the Tetrad framework. We applied several causal discovery algorithms to generate a support matrix and used the voting approach to find strong causal relationships. We demonstrated that our causal discovery results are consistent with a well-known economic model.
