Solving real-world problems with innovative and novel artifacts is at the core of design science research (DSR). Given DSR’s emphasis on a strong connection to the real-world, artifacts for solving a particular problem may not only be described in extant literature, but also exist in practice. This is particularly the case for software artifacts. T...

Depression is a large-scale and consequential problem in youth and young adults. Conversational agents (CAs) can contribute to addressing current barriers to seeking treatment, such as long waiting lists, and reduce the high dropout rates reported for other digital health interventions. However, existing CAs have not considered differences between...
Conference Paper
Labeling is critical in creating training datasets for supervised machine learning. It typically requires manual labor, is costly, and not infrequently frustrates the workers involved. Although task variety drives human autonomy and intrinsic motivation, there is little research in this regard in the labeling context. Against this backdrop, we mani...
Conference Paper
As machine learning continues to grow in popularity, so does the need for labeled training data. Crowd workers often have to tag, label, or annotate these datasets in the course of a labour-intensive, monotonous, and error-prone process that can even be frustrating. However, current task and system designs typically disregard worker-centric issues....
