Doris is an interactive visualization search tool that allows you to explore the evolution of issues in presidential historical documents. You can search any word and see a graph of how many times the word has been mentioned in historical documents across presidents, types of speeches, and topics. The corpus for this search tool is the American Presidency Project at the University of California, Santa Barbara. To learn more about how this tool was built, please take a look at our paper.
