We aim to accomplish this by incorporating both social gaming features and(More)
This paper reports our approach to three specific tasks of the BioCreAtIvE II challenge: protein interaction sentences (PPI-ISS), protein interaction pairs (PPI-IPS) and gene normalization (GN). Our approach to software engineering and implementation decisions was based on addressing first and foremost the core problem of integrating knowledge extracted(More)
Taskville is an interactive visualization that aims to increase awareness of tasks that occur in the workplace. It utilizes gameplay elements and playful interaction to motivate continued use.
