In task-oriented dialogue systems the dialogue state tracker (DST) component
is responsible for predicting the state of the dialogue based on the dialogue
history. Current DST approaches rely on a predefined domain ontology, a fact
that limits their effective usage for large scale conversational agents, where
the DST constantly needs to be interfaced with ever-increasing services and
APIs. Focused towards overcoming this drawback, we propose a domain-aware
dialogue state tracker, that is completely data-driven and it is modeled to
predict for dynamic service schemas. The proposed model utilizes domain and
slot information to extract both domain and slot specific representations for a
given dialogue, and then uses such representations to predict the values of the
corresponding slot. Integrating this mechanism with a pretrained language model
(i.e. BERT), our approach can effectively learn semantic relations.

多域对话系统的域感知对话状态跟踪器
在面向任务的对话系统中,对话状态跟踪器 (DST) 组件负责根据对话历史预测对话状态。当前的 DST 方法依赖于预定义的域本体,这一事实限制了它们在大规模会话代理中的有效使用,其中 DST 不断需要与不断增加的服务和 API 接口。为了克服这个缺点,我们提出了一个域感知对话状态跟踪器,它是完全数据驱动的,并且被建模以预测动态服务模式。所提出的模型利用域和槽信息来提取给定对话的域和槽特定表示,然后使用这些表示来预测相应槽的值。将此机制与预训练的语言模型(即
