Motivation
• Why?
– Supporting ubiquituos informal learning by tagging the non‐
obvious in digital video
• What?
– Near‐real time collaborative multimedia annotation
– Multi‐device & multi‐purpose
• How?
– Cloud‐based Community Information System (CIS)
– Seamless user interaction across platforms and devices
– Community reflection and analytics using CIS success measures

• How can we scale up video tagging to support
informal learning at the work place?
• Objectives
– Mobile creation of videos with learning
materials (physical‐digital world)
– Tag the non‐obvious for informal
learning in communities (social media
layer)
– Scaffold meaningful learning by
exploiting (semantic) tagging information
(social semantic layer)
• Two regional clusters
– Construction (Germany)
– Healthcare (UK)
