The pseudopeople package generates realistic, simulated population data for entity resolution (ER) research. This enables algorithm development without using sensitive personal information, overcoming data access barriers in data science.
Area of Science:
- Data Science
- Computational Social Science
Background:
- Entity Resolution (ER) is crucial for data integration but hindered by privacy concerns surrounding personally identifiable information (PII).
- Restrictions on accessing authentic PII slow the development and testing of new ER methods and software.
- The pseudopeople Python package addresses this by generating simulated datasets for ER research.
Purpose of the Study:
- To develop and release a tool for generating realistic, noisy simulated population data for entity resolution (ER).
- To enable researchers to develop and test ER algorithms without compromising sensitive personal information.
Main Methods:
- Utilized the Vivarium simulation platform to create a dynamic model of individuals, families, households, and employment.
- Generated simulated censuses, surveys, and administrative data reflecting real-world population dynamics.
- Developed the pseudopeople Python package to add configurable noise to simulated data for realistic ER challenges.
Main Results:
- Produced over 900 gigabytes of simulated population data, representing hundreds of millions of individuals.
- Made a sample population of thousands openly available via the pseudopeople package.
- Provided access to larger simulated populations upon request, structured for ER research.
Conclusions:
- The pseudopeople package and its associated simulated data overcome PII access barriers in ER research.
- Facilitates the development, testing, and adoption of novel ER algorithms and software for large-scale population data.
