The document discusses testing a prototype for an online dictionary website. It describes the goal of allowing users to create accounts, save words to personal lexicons, and tag words. It then provides sample test questions to evaluate usability, such as how a user would log in, look up a word they previously saved, and save/tag a new word. Next, it lists heuristics for user interface design, such as maintaining visibility of system status, using natural language, allowing user control and undo/redo, consistency, and preventing errors.
