By using the information architecture, we were able to gather valuable feedback about the requirements and cognitive processes of the tumor board members. Those insights have helped us to develop a dashboard application that closely adapts to the specified needs and characteristics, and thus is primarily user-centric.

A so ware development screencast is a video that captures the screen of a developer working on a particular task while explaining its implementation details. Due to the increased popularity of so ware development screencasts (e.g., available on YouTube), we study how and to what extent they can be used as additional source of knowledge to answer developer's questions about, for example, the use of a speci c API. We rst di erentiate between development and other types of screencasts using video frame analysis. By using the Cosine algorithm, developers can expect ten development screencasts in the top 20 out of 100 di erent YouTube videos. We then extracted popular development topics on which screencasts are reporting on YouTube: database operations, system set-up, plug-in development, game development, and testing.Besides, we found six recurring tasks performed in development screencasts, such as object usage and UI operations.Finally, we conducted a similarity analysis by considering only the spoken words (i.e., the screencast transcripts but not the text that might appear in a scene) to link API documents, such as the Javadoc, to the appropriate screencasts. By using Cosine similarity, we identi ed 38 relevant documents in the top 20 out of 9455 API documents.
