体现的代理需要能够在自然语言中互动理解任务描述，并提出适当的后续问题以获取必要的信息，以有效地成功完成各种用户的任务。在这项工作中，我们提出了一组对话框，用于建模此类对话框，并注释教学数据集，其中包括3,000多个位置，以任务为导向的对话（总计包含39.5k个话语），并具有对话框ACT。 Teach-da是对Dialog ACT的第一个大型数据集注释，用于具体任务完成。此外，我们在培训模型中证明了该注释的数据集在标记给定话语的对话框行为中的使用，预测给定对话框历史记录的下一个响应的对话框行为，并使用对话框行为指导代理商的非第二语言行为。特别是，我们对对话记录任务的教学执行执行的实验，该模型预测在体现任务完成环境中要执行的低级操作的顺序，证明对话框行为可以将最终任务成功提高2分，以提高最终任务成功率到没有对话行为的系统。

在人类空间中运营的机器人必须能够与人的自然语言互动，既有理解和执行指示，也可以使用对话来解决歧义并从错误中恢复。为此，我们介绍了教学，一个超过3,000人的互动对话的数据集，以完成模拟中的家庭任务。一个有关任务的Oracle信息的指挥官以自然语言与追随者通信。追随者通过环境导航并与环境进行互动，以完成从“咖啡”到“准备早餐”的复杂性不同的任务，提出问题并从指挥官获取其他信息。我们提出三个基准使用教学研究体现了智能挑战，我们评估了对话理解，语言接地和任务执行中的初始模型的能力。

这项工作提出了一个新的对话数据集，即cookdial，该数据集促进了对任务知识了解的面向任务的对话系统的研究。该语料库包含260个以人类对任务为导向的对话框，其中代理给出了配方文档，指导用户烹饪菜肴。 Cookdial中的对话框展示了两个独特的功能：（i）对话流与支持文档之间的程序对齐； （ii）复杂的代理决策涉及分割长句子，解释硬说明并在对话框上下文中解决核心。此外，我们在假定的面向任务的对话框系统中确定了三个具有挑战性的（子）任务：（1）用户问题理解，（2）代理操作框架预测和（3）代理响应生成。对于这些任务中的每一个，我们都会开发一个神经基线模型，我们在cookdial数据集上进行了评估。我们公开发布烹饪数据集，包括对话框和食谱文档的丰富注释，以刺激对特定于域的文档接地对话框系统的进一步研究。

建立一个对话体现的代理执行现实生活任务一直是一个长期而又具有挑战性的研究目标，因为它需要有效的人类代理沟通，多模式理解，远程顺序决策等。传统的符号方法具有扩展和概括问题，而端到端的深度学习模型则遭受数据稀缺和高任务复杂性的影响，并且通常很难解释。为了从两全其美的世界中受益，我们提出了一个神经符号常识性推理（JARVIS）框架，用于模块化，可推广和可解释的对话体现的药物。首先，它通过提示大型语言模型（LLM）来获得符号表示，以了解语言理解和次目标计划，并通过从视觉观察中构建语义图。然后，基于任务和动作级别的常识，次目标计划和行动生成的符号模块。在Teach数据集上进行的大量实验验证了我们的JARVIS框架的功效和效率，该框架在所有三个基于对话框的具体任务上实现了最新的（SOTA）结果，包括对话记录（EDH）的执行，对话框的轨迹， （TFD）和两个代理任务完成（TATC）（例如，我们的方法将EDH看不见的成功率从6.1 \％\％提高到15.8 \％）。此外，我们系统地分析了影响任务绩效的基本因素，并在几个射击设置中证明了我们方法的优越性。我们的Jarvis模型在Alexa奖Simbot公共基准挑战赛中排名第一。

语言指导的体现了AI基准，要求代理导航环境并操纵对象通常允许单向通信：人类用户向代理提供了自然语言命令，而代理只能被动地遵循命令。我们介绍了基于Alfred基准测试的基准测试后的拨号式拨号。Dialfred允许代理商积极向人类用户提出问题；代理使用用户响应中的其他信息来更好地完成其任务。我们发布了一个具有53K任务的问题和答案的人类注销数据集，以及一个可以回答问题的甲骨文。为了解决Dialfred，我们提出了一个提问者绩效框架，其中发问者通过人类通知的数据进行了预训练，并通过增强学习进行了微调。我们将拨号拨入公开，并鼓励研究人员提出和评估他们的解决方案，以构建支持对话的体现代理。

End-to-end task bots are typically learned over a static and usually limited-size corpus. However, when deployed in dynamic, changing, and open environments to interact with users, task bots tend to fail when confronted with data that deviate from the training corpus, i.e., out-of-distribution samples. In this paper, we study the problem of automatically adapting task bots to changing environments by learning from human-bot interactions with minimum or zero human annotations. We propose SL-AGENT, a novel self-learning framework for building end-to-end task bots. SL-AGENT consists of a dialog model and a pre-trained reward model to predict the quality of an agent response. It enables task bots to automatically adapt to changing environments by learning from the unlabeled human-bot dialog logs accumulated after deployment via reinforcement learning with the incorporated reward model. Experimental results on four well-studied dialog tasks show the effectiveness of SL-AGENT to automatically adapt to changing environments, using both automatic and human evaluations. We will release code and data for further research.

最近，通过“向导”模拟游戏收集了一类以任务为导向的对话（TOD）数据集。但是，《巫师》数据实际上是模拟的数据，因此与现实生活中的对话根本不同，这些对话更加嘈杂和随意。最近，Seretod挑战赛是组织的，并发布了Mobilecs数据集，该数据集由来自中国移动的真实用户和客户服务人员之间的真实世界对话框组成。基于Mobilecs数据集，Seretod挑战具有两个任务，不仅评估了对话系统本身的构建，而且还检查了对话框成绩单中的信息提取，这对于建立TOD的知识库至关重要。本文主要介绍了Mobilecs数据集对这两项任务的基线研究。我们介绍了如何构建两个基线，遇到的问题以及结果。我们预计基线可以促进令人兴奋的未来研究，以建立针对现实生活任务的人类机器人对话系统。

与具有粗粒度信息的Crosswoz（中文）和多发性（英文）数据集相比，没有数据集，可以正确处理细粒度和分层级别信息。在本文中，我们在香港发布了一份粤语知识驱动的对话数据集（KDDRES），将多转谈话中的信息放在一个特定的餐厅。我们的语料库包含0.8k次谈话，它来自10家餐厅，提供不同地区的各种风格。除此之外，我们还设计了细粒度的插槽和意图，以更好地捕获语义信息。基准实验和数据统计分析显示了我们数据集的多样性和丰富的注释。我们认为，KDDRE的出版可以是当前对话数据集的必要补充，以及社会中小企业（中小企业）更适合和更有价值，如为每家餐馆建立定制的对话系统。语料库和基准模型是公开可用的。

We present BotSIM, a data-efficient end-to-end Bot SIMulation toolkit for commercial text-based task-oriented dialog (TOD) systems. BotSIM consists of three major components: 1) a Generator that can infer semantic-level dialog acts and entities from bot definitions and generate user queries via model-based paraphrasing; 2) an agenda-based dialog user Simulator (ABUS) to simulate conversations with the dialog agents; 3) a Remediator to analyze the simulated conversations, visualize the bot health reports and provide actionable remediation suggestions for bot troubleshooting and improvement. We demonstrate BotSIM's effectiveness in end-to-end evaluation, remediation and multi-intent dialog generation via case studies on two commercial bot platforms. BotSIM's "generation-simulation-remediation" paradigm accelerates the end-to-end bot evaluation and iteration process by: 1) reducing manual test cases creation efforts; 2) enabling a holistic gauge of the bot in terms of NLU and end-to-end performance via extensive dialog simulation; 3) improving the bot troubleshooting process with actionable suggestions. A demo of our system can be found at https://tinyurl.com/mryu74cd and a demo video at https://youtu.be/qLi5iSoly30. We have open-sourced the toolkit at https://github.com/salesforce/botsim

部署后，AI代理会遇到超出其自动解决问题能力的问题。利用人类援助可以帮助代理人克服其固有的局限性，并坚决应对陌生的情况。我们提出了一个通用的交互式框架，该框架使代理商能够从对任务和环境有知识的助手那里请求和解释丰富的上下文有用的信息。我们在模拟的人类辅助导航问题上证明了框架的实用性。在我们的方法中学到的援助要求政策的帮助下，导航代理与完全自主行为相比，在以前看不见的环境中发生的任务上的成功率提高了7倍。我们表明，代理商可以根据上下文来利用不同类型的信息，并分析学习援助要求政策的好处和挑战，当助手可以递归地将任务分解为子任务。

Training dialogue systems often entails dealing with noisy training examples and unexpected user inputs. Despite their prevalence, there currently lacks an accurate survey of dialogue noise, nor is there a clear sense of the impact of each noise type on task performance. This paper addresses this gap by first constructing a taxonomy of noise encountered by dialogue systems. In addition, we run a series of experiments to show how different models behave when subjected to varying levels of noise and types of noise. Our results reveal that models are quite robust to label errors commonly tackled by existing denoising algorithms, but that performance suffers from dialogue-specific noise. Driven by these observations, we design a data cleaning algorithm specialized for conversational settings and apply it as a proof-of-concept for targeted dialogue denoising.

Many efforts have been made to construct dialog systems for different types of conversations, such as task-oriented dialog (TOD) and open-domain dialog (ODD). To better mimic human-level conversations that usually fuse various dialog modes, it is essential to build a system that can effectively handle both TOD and ODD and access different knowledge sources. To address the lack of available data for the fused task, we propose a framework for automatically generating dialogues that combine knowledge-grounded ODDs and TODs in various settings. Additionally, we introduce a unified model PivotBot that is capable of appropriately adopting TOD and ODD modes and accessing different knowledge sources in order to effectively tackle the fused task. Evaluation results demonstrate the superior ability of the proposed model to switch seamlessly between TOD and ODD tasks.

Empathy is a vital factor that contributes to mutual understanding, and joint problem-solving. In recent years, a growing number of studies have recognized the benefits of empathy and started to incorporate empathy in conversational systems. We refer to this topic as empathetic conversational systems. To identify the critical gaps and future opportunities in this topic, this paper examines this rapidly growing field using five review dimensions: (i) conceptual empathy models and frameworks, (ii) adopted empathy-related concepts, (iii) datasets and algorithmic techniques developed, (iv) evaluation strategies, and (v) state-of-the-art approaches. The findings show that most studies have centered on the use of the EMPATHETICDIALOGUES dataset, and the text-based modality dominates research in this field. Studies mainly focused on extracting features from the messages of the users and the conversational systems, with minimal emphasis on user modeling and profiling. Notably, studies that have incorporated emotion causes, external knowledge, and affect matching in the response generation models, have obtained significantly better results. For implementation in diverse real-world settings, we recommend that future studies should address key gaps in areas of detecting and authenticating emotions at the entity level, handling multimodal inputs, displaying more nuanced empathetic behaviors, and encompassing additional dialogue system features.

People capture photos and videos to relive and share memories of personal significance. Recently, media montages (stories) have become a popular mode of sharing these memories due to their intuitive and powerful storytelling capabilities. However, creating such montages usually involves a lot of manual searches, clicks, and selections that are time-consuming and cumbersome, adversely affecting user experiences. To alleviate this, we propose task-oriented dialogs for montage creation as a novel interactive tool to seamlessly search, compile, and edit montages from a media collection. To the best of our knowledge, our work is the first to leverage multi-turn conversations for such a challenging application, extending the previous literature studying simple media retrieval tasks. We collect a new dataset C3 (Conversational Content Creation), comprising 10k dialogs conditioned on media montages simulated from a large media collection. We take a simulate-and-paraphrase approach to collect these dialogs to be both cost and time efficient, while drawing from natural language distribution. Our analysis and benchmarking of state-of-the-art language models showcase the multimodal challenges present in the dataset. Lastly, we present a real-world mobile demo application that shows the feasibility of the proposed work in real-world applications. Our code and data will be made publicly available.

如何有效地构建和使用对话数据，以及如何在不同域中在不同域中部署模型可能是建立面向任务的对话系统的两个关键问题。在本文中，我们提出了一种新颖的手动指导对话方案，以减轻这些问题，在该方案中，代理商从对话和手册中学习任务。该手册是一个非结构化的文本文档，可指导代理在对话过程中与用户和数据库进行交互。我们提出的方案降低了对话模型对细粒领域本体的依赖性，并使它们更灵活以适应各种领域。然后，我们为完全注销的多域数据集Magdial贡献以支持我们的方案。它介绍了三个对话建模子任务：指令匹配，参数填充和响应生成。对这些子任务进行建模与人类代理的行为模式一致。实验表明，手动引导对话方案提高了构建对话系统中的数据效率和域可伸缩性。数据集和基准将公开用于促进未来的研究。

由于人类参与者的参与，收集培训对话系统的数据可能非常昂贵，并且需要广泛的注释。特别是在文档接地的对话系统中，人类专家需要仔细阅读非结构化文件以回答用户的问题。结果，现有的文档接地对话对话数据集相对较小，并且妨碍了对话系统的有效培训。在本文中，我们提出了一种通过生成对话模型在文档上接地的自动数据增强技术。对话模型由用户BOT和代理机器人组成，可以在给定输入文档的情况下合成不同的对话，然后用于训练下游模型。在补充原始数据集时，我们的方法可以实现对传统数据增强方法的显着改进。我们还在低资源环境中实现了良好的性能。

在过去的十年中，对对话系统的兴趣已经大大增长。从扩展过程中，也有兴趣开发和改进意图分类和插槽填充模型，这是两个组件，这些组件通常在以任务为导向的对话框系统中使用。此外，良好的评估基准对于帮助比较和分析结合此类模型的系统很重要。不幸的是，该领域的许多文献仅限于对相对较少的基准数据集的分析。为了促进针对任务的对话系统的更强大的分析，我们对意图分类和插槽填充任务进行了公开可用数据集的调查。我们分类每个数据集的重要特征，并就每个数据集的适用性，优势和劣势进行讨论。我们的目标是，这项调查有助于提高这些数据集的可访问性，我们希望它们能够在未来评估意图分类和填充插槽模型中用于以任务为导向的对话框系统。

从对话数据中提取信息特别具有挑战性，因为以任务为中心的对话的性质可以有效地传达人类隐式信息，但对机器来说是具有挑战性的。话语之间的挑战可能会有所不同，具体取决于说话者在对话中的作用，尤其是当相关专业知识跨角色不对称时。此外，随着对话中隐含地传达的信息构建更多的共享环境，挑战也可能会增加。在本文中，我们提出了新颖的建模方法MedFilter，该方法解决了这些见解，以提高识别和分类与任务相关的话语时的性能，并在这样做时对下游信息提取任务的性能产生积极影响。我们在近7,000次医生对话的语料库上评估了这种方法，其中使用MedFilter来识别与讨论的医学相关贡献（在PR曲线下的面积方面，比SOTA基线提高了10％的贡献）。确定与任务相关的话语受益于下游医疗处理，在提取症状，药物和投诉的提取方面分别提高了15％，105％和23％。

We introduce BotSIM, a modular, open-source Bot SIMulation environment with dialog generation, user simulation and conversation analytics capabilities. BotSIM aims to serve as a one-stop solution for large-scale data-efficient end-to-end evaluation, diagnosis and remediation of commercial task-oriented dialog (TOD) systems to significantly accelerate commercial bot development and evaluation, reduce cost and time-to-market. BotSIM adopts a layered design comprising the infrastructure layer, the adaptor layer and the application layer. The infrastructure layer hosts key models and components to support BotSIM's major functionalities via a streamlined "generation-simulation-remediation" pipeline. The adaptor layer is used to extend BotSIM to accommodate new bot platforms. The application layer provides a suite of command line tools and a Web App to significantly lower the entry barrier for BotSIM users such as bot admins or practitioners. In this report, we focus on the technical designs of various system components. A detailed case study using Einstein BotBuilder is also presented to show how to apply BotSIM pipeline for bot evaluation and remediation. The detailed system descriptions can be found in our system demo paper. The toolkit is available at: https://github.com/salesforce/BotSIM .

Virtual assistants such as Google Assistant, Alexa and Siri provide a conversational interface to a large number of services and APIs spanning multiple domains. Such systems need to support an ever-increasing number of services with possibly overlapping functionality. Furthermore, some of these services have little to no training data available. Existing public datasets for task-oriented dialogue do not sufficiently capture these challenges since they cover few domains and assume a single static ontology per domain. In this work, we introduce the the Schema-Guided Dialogue (SGD) dataset, containing over 16k multi-domain conversations spanning 16 domains. Our dataset exceeds the existing task-oriented dialogue corpora in scale, while also highlighting the challenges associated with building large-scale virtual assistants. It provides a challenging testbed for a number of tasks including language understanding, slot filling, dialogue state tracking and response generation. Along the same lines, we present a schema-guided paradigm for task-oriented dialogue, in which predictions are made over a dynamic set of intents and slots, provided as input, using their natural language descriptions. This allows a single dialogue system to easily support a large number of services and facilitates simple integration of new services without requiring additional training data. Building upon the proposed paradigm, we release a model for dialogue state tracking capable of zero-shot generalization to new APIs, while remaining competitive in the regular setting.
