Tools for computational news
detection & verification
SocialSensor is a single tool that
quickly surfaces trusted news
stories from social media – with
context.
A Single Tool: one platform, one interface
Quickly: in real time
Surfaces: automatically discovers and clusters
Trusted: automatic support in verification process
Material: any material (text, image, audio, video =
multimedia)
Social Media: across relevant social media platforms
With Context: location, time, sentiment, influence
1. To what extent does social media
break news first, and how much
news does it carry that’s not
covered elsewhere?
2. And, in addition to ‘surfacing’ news,
what else can tools like Social
Sensor do?
