This paper describes the redevelopment of National Center for Forensic Science databases focused on fire debris analysis.

Abstract

This project redeveloped a resource for casework whereby the Ignitable Liquids Reference Collection (ILRC) and Substrate databases share the same web interface as well as to create a large dataset of in-silico fire debris data for development and application of machine learning methods. Three NCFS databases focusing on fire debris analysis were redeveloped and are now accessible from a singular website. Redevelopment of the databases included new programming, design, and additional security features while maintaining the functionality users expect. Another accomplishment was completing research on the development of in-silico fire debris data. The results are four datasets each containing 60,000 records of in-silico fire debris. An additional dataset is laboratory generated fire debris from the Fire Debris database. These datasets are available on the Database website for use in machine learning. The database website, accessible at https://ilrc.ucf.edu/, is hosted by the National Center for Forensic Science at the University of Central Florida. The Homepage provides information about the databases, what is new, and their history. ILRC Substrate-Fire Debris contains several pages providing information about each database, how to order ignitable liquid reference materials, and contact information.
