The approach (1/2) • Recovering Roles and Their Mappings to Tasks • Recovering Task-UI Bindings. To match: – the task name with the names of UI components – the task name with the names of a widget in a UI component – the task name with the data items in a UI component – The name of a task with the names of function calls (callback) – The input and output data of a task with the data.
