Like an iceberg, the vast majority of the Rijksmuseum’s collection is hidden. But not for much longer. The museum now runs a program to digitize artworks and put the objects online. To help the curators annotate the items Delft researchers develop methods to harvest expertise from the crowd. PhD student Jasper Oosterman (EEMCS) has recently done a first trial run with eighty-six prints of birds and plants. He develops strategies and software to identify potential contributors and to assemble them into a working crowd. This is one of over forty research projects that were presented on Delft Data Science New Year Event, held at the EEMCS building on January 13.
