Investigating With Databases: Verifying Data Quality

Editor’s Note: The Verification Handbook for Investigative Reporting is a new guide to online search and research techniques to using user-generated content and open source information in investigations.

We’re pleased to reprint below chapter 5, by investigative journalist Giannina Segnini.

A Guide to Verifying Digital Content in Emergencies

The Verification Handbook is a new resource for journalists and aid responders, with step-by-step guidelines for using using information generated by the public. Although targeted for use during emergencies, the handbook provides useful tips for verifying crowd-sourced information in general. Thanks to the European Journalism Centre, which developed the handbook, for allowing GIJN to publish this excerpt.
