Technical Colloquium on the Weight of Evidence


NIST will host the 2017 Technical Colloquium on the Weight of Evidence (WoE) on June 27-29, 2017.  How can we transition the reporting of forensic results from simple “match/no match” statements to statements that integrate error and uncertainty? Join us at this colloquium, where experts from a broad array of forensic disciplines will share ideas on this issue.

The first day will be about defining the weight of evidence - what it means and how to quantify it. The second day will cover collecting evidence and analyzing data with these quantification challenges in mind. The third day will focus on communicating and reporting findings of forensic examination.
