Software

I develop open-source software to support data curation, computational social science research, and teaching. I also build lightweight tools for instructional and practical use. All packages are freely available on GitHub: github.com/jaeyk

1. PracticeTalk: A simple, lightweight speech synthesis web app that turns your talk script into an audio file, allowing you to check its flow and narrative.

2. ClassKit: A lightweight suite of browser-based classroom utilities. Upload a roster, choose your options, and generate reproducible student samples for cold calling, breakout groups, preference-based project teams, and peer-review matches. No installation required.

3. MapAgora

   • Summary: An R package for retrieving and processing tax records (e.g., IRS Form 990), website data, and social media handles for U.S. nonprofit organizations. Built to support large-scale analysis of civic infrastructure.
   • Use case: Used in “MapAgora, Civic Opportunity Datasets for the Study of American Local Politics and Public Policy”, Nature: Scientific Data (2025), and “The Unequal Landscape of Civic Opportunity in America”, Nature Human Behaviour (2023), with Milan de Vries and Hahrie Han
   • Collaborator: Milan de Vries

4. autotextclassifier

   • Summary: An R package for automated text classification using the tidymodels framework. Supports supervised learning pipelines with minimal setup for civic tech and policy research applications.
   • Use case: Used in “MapAgora, Civic Opportunity Datasets for the Study of American Local Politics and Public Policy”, Nature: Scientific Data (2025), and “The Unequal Landscape of Civic Opportunity in America”, Nature Human Behaviour (2023), with Milan de Vries and Hahrie Han
   • Collaborator: Milan de Vries

5. validatednamesr

   • Summary: An R package for accessing and analyzing the validated names dataset used in race and ethnicity experiments. Includes utilities for name filtering, trait inspection, and integration with survey tools.
   • Use case: Featured in “Validated Names for Experimental Studies on Ethnicity and Race”, Nature: Scientific Data (2023), with by Charles Crabtree, S. Michael Gaddis, John B. Holbein, Cameron Guage, and William Marx.
   • Collaborator: Charles Crabtree

6. tidytweetjson

   • Summary: An R package that transforms raw Twitter JSON files into clean, analysis-ready datasets. Useful for studying political discourse, social movements, and real-time reactions to events.
   • Use case: Used in “COVID-19 and Asian Americans: How Elite Messaging and Social Exclusion Shape Partisan Attitudes”, Perspectives on Politics (2021), with Nathan Chan and Vivien Leung.

7. tidyethnicnews

   • Summary: An R package for scraping, cleaning, and organizing ethnic newspaper articles from the Ethnic NewsWatch database. Designed to support media analysis and political communication research.
   • Use case: Used in “Integrating Human and Machine Coding to Measure Political Issues in Ethnic Newspaper Articles”, Journal of Computational Social Science (2021)
