Leveraging Community-Generated Videos and Command Logs to Classify and Recommend Software Workflows

Users of complex software applications often rely on inefficient or suboptimal workflows because they are not aware that better methods exist. In this paper, we develop and validate a hierarchical approach combining topic modeling and frequent pattern mining to classify the workflows offered by an application, based o…

Blocks-to-CAD : A Cross-Application Bridge from Minecraft to 3D Modeling

Learning a new software application can be a challenge, requiring the user to enter a new environment where their existing knowledge and skills do not apply, or worse, work against them. To ease this transition, we propose the idea of cross-application bridges that start with the interface of a familiar application, a…
