We spent two days in the Grand Hotell in Egersund working on a framework for Personal Knowledge Graphs (PKGs). The outing was devoted to discussions, hands-on coding, and group activities. The PKG ecosystem has been defined in our recently submitted paper. Apart from hard work, we made use of beautiful weather and enjoyed a hike to Trollpikken. Photos from the outing can be found here.

IAI outing and hackathon
We spent a day in Utstein Monastery Hotel in Mosterøy working on bringing back to life and planning further development of our conversational movie recommender system, the IAI MovieBot. The outing was devoted to discussions, hands-on coding, and group activities. The original IAI MovieBot is described in a CIKM’20 demo paper [PDF]. Photos from the outing can be found here.
