Text Mining and Spatial Analysis of Yelp Data to Support Socially Vibrant Cities by Alexander Bendeck and Clio Andris
Published in Urban Computing
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.
Published in the Journal of Urbanism
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.
Lessons From a Human-In-The-Loop Machine Learning Approach for Planning: Identifying Vacant, Abandoned, and Disinvested Properties in Savannah, Georgia
by Xiaofan Liang, Brian Brainerd, Tara Hicks, Clio Andris
Publication in progress
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.
Place Social Diversity: A New Attribute for Points of Interest
by Seolha Lee and Clio Andris
Points of Interest (POIs) provide opportunities for social interaction among different social groups, which is crucial for cultivating strong and healthy communities. In this study, we create a Place Diversity Index (PDI) to measure the social diversity of visitors at POIs using trip data from mobile GPS traces. Using this index, we analyze what makes a destination socially diverse through a case study in Atlanta, Georgia. The result shows that in Atlanta, POIs are largely segregated, yet food places are most socially diverse. Also, socially diverse POIs are located in higher-income, more white neighborhoods, and areas expe riencing advanced gentrification. The method we explore in this study, which annotates a place with the socio-demographic heterogeneity of visitors, can be generalized into other cities and be useful for practitioners and researchers who want to promote social diversity in places through place-based interventions.

Info about our closing event (2023)
Savannah Smart Cities Closing Community Event: All are welcome!
Purpose: In this event, we will share new knowledge from a practitioner/ academic partnership in the City of Savannah on the topics of housing and social life in Savannah. We will share powerpoint presentations about our research, hear from a City of Savannah planner about what is new in the city, and have a roundtable discussion after lunch to discuss initiatives and needs.
Date + Time: Friday, August 11th, 9 AM -1:15 PM (networking and chatting roundtable session afterwards)
Location: Coastal Georgia Center, Main Auditorium, 305 Fahm St, Savannah, GA 31401 [map]
Who can attend: Any Savannah resident, practitioners from Georgia in city planning or in related positions
Organizers: This event is sponsored by the Partnership for Inclusive Innovation.
Event Program
8:30 AM: Pastries and coffee from Sentient Bean
9:00 AM: Welcome & Opening Remarks: Why Planners Need Smart Cities
What urban planners can do depends on what dimensions of a city and its people can be measured. Currently, there are numerous quantitative measures available from Census and administrative data. Qualitative measures are more elusive. A few examples of quantitative and qualitative measures will be presented as a framework for the Savannah’s Smart Communities projects to be presented today.
9:15 AM: Words from Partnership for Inclusive Innovation, Project Sponsor
The Partnership for Inclusive Innovation (PIN) is a public-private partnership that began in 2020 via an initiative by Georgia’s Lt. Gov. Geoff Duncan. The project runs pilot programs across Georgia in places like Metro Atlanta, Macon, Columbus, Valdosta, Savannah and other places. These projects pair up academics with local governments and practitioners, and many of the projects have a “smart” or technical element to them, and/or a job training component. PIN has four pillars: economic opportunity, student engagement, community research and workforce development.
9:30 AM: Overview of Our Partnership
This program will present research from an academic partnership with the City of Savannah since 2020. These projects have been sponsored by the Partnership for Inclusive Innovation and have been led by Brian Brainerd, Meimei Lin, and Clio Andris, and have trained 5 university students. The first project that we will discuss is VADecide, a human-in-the-loop machine learning tool that was built for the City of Savannah to help them detect parcels that were vacant, abandoned or disinvested, using geographic information systems data. The second project we will discuss is the SavannahSocial project, which has two components. Through an intercept survey and an interview survey, we aim to collect information on the places where people spend time in Savannah to socialize, their perceptions of Savannah, and how the city can help make peoples’ social networks stronger.
9:45 AM: Savannah Vacant Abandoned and Disinvested (VAD) Properties Project
Our team will present a project where we created a human-in-the-loop machine learning approach for identifying vacant, abandoned, and disinvested (VAD) properties in Savannah, Georgia. This team of four practitioners and two academic researchers produced a machine learning model that inputs data about the city’s parcels (tax records, year built, neighborhood condition, crime reports, etc.) and predicts parcels that may need attention from the city. The model takes in practitioners’ knowledge and applies it to more neighborhoods in Savannah than the city’s traditional approaches typically can cover.
10:15 AM: Coffee Break
10:45 AM: SavannahSocial Short Form Survey
The Georgia Southern team will present the Savannah Social Short Form survey, conducted during community engagement events at the Savannah Farmers' Market. This survey collects information on individuals' experiences, perceptions of social spaces, locations to avoid, reasons for avoidance, and potential improvements for enhancing social life in the city. Our presentation will provide a comprehensive overview of the survey's outcomes, highlighting positive aspects and addressing challenges. We will showcase a map of Points of Interest (POIs) identified by participants and their accessibility across neighborhoods, emphasizing disparities and challenges faced by specific groups. We will explore reasons for place avoidance in Savannah and share valuable recommendations and best practices for other communities undertaking similar studies. By outlining our lessons learned, we aim to inspire innovative approaches to community engagement and data-driven decision-making.
11:30 PM: SavannahSocial Interview Project
Coastal Georgia Indicators Coalition (CGIC) representatives will talk about the Savannah Social Long Form survey, an interview-based survey that engages local residents. This survey asks about people’s relationships and what they do together / where they go in the city to help support those relationships. The interview also takes in suggestions about what infrastructure can be built to help people spend more time together outside the home. This is the first known interview data collection effort that explicitly pins people’s types of ties (family, friend, romantic relationship, co-worker, etc.) to neighborhoods and specific destinations.
11:55 AM: Savannah’s Inclusive Planning Initiatives
An overview of how the City of Savannah is making inclusion and equity a feature of current planning activities in the City of Savannah to address the needs of historically marginalized populations.
12:25 PM: Closing Remarks
12:30 - 1:15 PM: Lunch from Sentient Bean (they are veggie :) ).
1:15 PM: Academic / Practitioner Roundtable. All are welcome to stay after lunch and for a discussion with researchers and planning practitioners regarding how the survey methodology studied in the Savannah Social project could be a useful tool for neighborhood planning and development.
