After a few months of development, Heliograf debuted last year. An early version autopublished stories on the Rio Olympics (image below of the tweets it sent); a more advanced version, with a stronger editorial voice, was soon introduced to cover the election. It works like this: Editors create narrative templates for the stories, including key phrases that account for a variety of potential outcomes (from “Republicans retained control of the House” to “Democrats regained control of the House”), and then they hook Heliograf up to any source of structured data—in the case of the election, the data clearinghouse VoteSmart.org. The Heliograf software identifies the relevant data, matches it with the corresponding phrases in the template, merges them, and then publishes different versions across different platforms. The system can also alert reporters via Slack of any anomalies it finds in the data—for instance, wider margins than predicted—so they can investigate. “It’s just one more way to get a tip” on a potential scoop, Gilbert says.
