Together with Wanno Drijfhout and Oliver Jundt, I won the Norvig Web Data Science Award. This is a challenge where participants show what they can do with the Common Crawl dataset -- a snapshot of a large part of the web -- using SurfSARA’s Hadoop cluster to provide big data compute power. Our entry uses the dataset to construct a database of associated concepts, which can be queried through a web application with two query interfaces. A textual interface allows searching for similarities and differences between multiple concepts using a query language similar to set notation, and a graphical interface allows users to visualize similarity relationships of concepts in a force directed graph. You can watch the video below for a presentation of Traitor by Wanno.
