Before revision: Playing text-based games requires skill in processing natural language and in planning. Although a key goal for agents solving this task is to generalize across multiple games , most previous work has either focused on solving a single game or has tackled generalization with rule-based heuristics.
After revision: Playing text-based games requires skill in processing natural language and sequential decision making. Achieving human-level performance on text-based games remains an open challenge, and prior research has largely relied on hand-crafted structured representations and heuristics.
