Optimizing multimedia and gameplay data labeling: A web-based tool for Game-Based Assessment

In this research, we introduce a novel open-source labeling tool, the Game-Based Assessment (GBA) Labeling Tool, specifically designed to address current challenges for data labeling in GBA scenarios. This web-based application facilitates the annotation of audio, video, and game event data, offering three different types of annotations - global, time instant, and time window annotations - to enhance accuracy in the labeling process. The tool also offers customizable labels and various types of visualizations to support different contexts and scenarios.
