In this paper, we consider the task of learning control policies for
text-based games. In these games, all interactions in the virtual world are
through text and the underlying state is not observed. The resulting language
barrier makes such environments challenging for automatic game players. We
employ a deep reinforcement learning framework to jointly learn state
representations and action policies using game rewards as feedback. This
framework enables us to map text descriptions into vector representations that
capture the semantics of the game states. We evaluate our approach on two game
worlds, comparing against baselines using bag-of-words and bag-of-bigrams for
state representations. Our algorithm outperforms the baselines on both worlds
demonstrating the importance of learning expressive representations.

本文探讨了基于文本的游戏控制策略的学习方法。该方法使用深度强化学习框架，联合学习游戏状态表示和行动策略。通过把文本转化为向量，能够更好地捕捉游戏状态的语义表示。实验结果表明，我们提出的方法显著优于传统基于词袋模型的方法。
