An incredibly diverse group of participants came together over Yelp Montreal’s Yackathon weekend to compete including: post-doctoral neurologists, meteorologists, masters of engineering, urban planners, health psychologists, illustrators, and self-described ‘corporate drones’ fleeing their cubicles for the weekend (fly free!). In total 15 teams delved into Yelp’s open API and Academic Dataset over the weekend, and met our challenge to mash up our data with any other open data set.
