摘要:

像Cortana、Siri、Alexa和Google Assistant这样的智能助理都经过训练,可以在对话同步且简短的情况下解析信息;然而,对于基于电子邮件的会话代理,通信是异步的,并且通常包含与助理无关的信息。这使得系统更难以准确地检测意图,提取与这些意图相关的实体,从而执行所需的动作。我们提出了一个神经模型,用于从大型查询中为代理确定相关信息的范围。我们表明,当用作预处理步骤时,该模型提高了意图检测和实体提取任务的性能。我们展示了该模型对代理的影响(Cortana是代理的角色,而代理是服务的名称。在本文中,我们可以互换使用它们。)- 一种虚拟会话会议安排助理,通过电子邮件与用户异步交互。该模型帮助实体提取和意图检测任务所需的搜索引擎实现了平均35%的准确率,而没有任何下降的召回。此外,我们证明了相同的方法可以用于大型文档中的组件级分析,例如签名块识别。

英文摘要:

Intelligent assistants like Cortana, Siri, Alexa, and Google Assistant are trained to parse information when the conversation is synchronous and short; however, for email-based conversational agents, the communication is asynchronous, and often contains information irrelevant to the assistant. This makes it harder for the system to accurately detect intents, extract entities relevant to those intents and thereby perform the desired action. We present a neural model for scoping relevant information for the agent from a large query. We show that when used as a preprocessing step, the model improves performance of both intent detection and entity extraction tasks. We demonstrate the model's impact on Scheduler (Cortana is the persona of the agent, while Scheduler is the name of the service. We use them interchangeably in the context of this paper.) - a virtual conversational meeting scheduling assistant that interacts asynchronously with users through email. The model helps the entity extraction and intent detection tasks requisite by Scheduler achieve an average gain of 35% in precision without any drop in recall. Additionally, we demonstrate that the same approach can be used for component level analysis in large documents, such as signature block identification.
