We used Yelp online reviews of places of interest to search for social relationship words (like mother, father, partner, boyfriend, girlfriend, friend, and coworker, for example) in eight US cities. We then mapped where in a city certain relationships spend time and found that certain places of interest (restaurants, shopping, etc.) support different types of relationships.
The map to the right shows a comparison of hot spots, or places with a significant number of Yelp reviews, specific to romantic and familial relationships.
In addition, we also made an interactive online tool that lets users select a relationship type of interest (such as "romantic" or "family") and search for places whose reviews mention these relationships. This tool can be found here.

We used geographic information system (GIS) and surveys of people in romantic relationships to locate where couples spend time in State College, Pennsylvania. We found that pedestrian and transportation infrastructure as well as a variety of close and affordable activities are particularly important for couples.
The map to the left shows the home locations of survey respondents, partners who live together and partners who live apart, and the top ten places of interest (POIs) such as the movie theater or certain restaurants.

In this project, we used a human-in-the-loop machine learning model (a tool that combines human insights and statistics) to identify vacant, abandoned, and disinvested (VAD) properties in Savannah, Georgia. This method revealed that tax delinquency, code violations, and crime history were the best indicators of VAD properties.
The map to the right shows the difference between VAD properties as identified by the model versus identified by human judgement.
