World models improve a learning agent's ability to efficiently operate in interactive and situated environments. This work focuses on the task of building world models of text-based game environments. Text-based games, or interactive narratives, are reinforcement learning environments in which agents perceive and interact with the world using textual natural language. These environments contain long, multi-step puzzles or quests woven through a world that is filled with hundreds of characters, locations, and objects. Our world model learns to simultaneously: (1) predict changes in the world caused by an agent's actions when representing the world as a knowledge graph; and (2) generate the set of contextually relevant natural language actions required to operate in the world. We frame this task as a Set of Sequences generation problem by exploiting the inherent structure of knowledge graphs and actions and introduce both a transformer-based multi-task architecture and a loss function to train it. A zero-shot ablation study on never-before-seen textual worlds shows that our methodology significantly outperforms existing textual world modeling techniques as well as the importance of each of our contributions.

诸如开放域问答之类的自然语言理解任务通常需要从多个源检索和吸收事实信息。我们建议通过将大型文本语料库的半参数表示集成到Transformer模型中作为事实知识的来源来解决这个问题。具体来说,我们的方法表示知识与“提及记忆”,一个表的密集向量表示的每一个实体中提到的语料库。所提出的模型- TOME -是一个Transformer,它通过内部记忆层访问信息,其中输入通道中提到的每个实体都参与提到记忆。这种方法支持在单个Transformer模型中对许多不同的信息源进行合成和推理。在使用1.5亿次维基百科提及的记忆的实验中,TOME在几个开放领域知识密集型任务上实现了强大的性能,包括声明验证基准HoVer和FEVER以及几个基于实体的QA基准。我们还表明,该模型学习参加信息提及没有任何直接的监督。最后,我们证明了该模型可以推广到新的看不见的实体更新的内存,而无需再训练。
