From a requirements engineering point of view, the elicitation of context-aware functionalities calls for context modeling, an early step that aims at understanding the application contexts and how it may influence user tasks. In practice, however, context modeling activities have been overlooked by practitioners due to their high complexity. To improve this situation, we implemented xPACE and TASC Modeler, which are tools that support the automation of context modeling based on existing contextual data. In this demonstration paper, we present our implementation of a data-driven context modeling approach, which is composed of a contextual data processor (xPACE) and a context model generator (TASC Modeler). We successfully evaluated the results provided by the tools in a software development project.
