NIJ Innovations in Measuring Community Perceptions Challenge Winner: ScienceCast

This entry proposes to leverage information in the Police Score Card Database (PCSD), Wikidata, and Twitter to measure community perception constructs. The PSCD is a nationwide database of policing indicators gathered from state and federal databases as well as media reports and public records requests. A framework describing relationships within these sources would be developed and used to inform the creation of a knowledge graph. The proposed method employs a variety of machine learning tools to process the data and sentiment analysis to quantify community perceptions of the constructs, highlighting novel strategies and tools for analyzing existing data regarding community perceptions.

Team members included John Beverly and Andrew Jiranek.

This entry won third prize in the category 2 overall competition.
