我们提出了一个基于深度学习的外语学习平台，命名为FreeLalky，因为使用人形机器人NAO和各种深入学习模型，他们会受到对外语言的焦虑的人。嵌入在NAO的基于角色的对话系统为用户提供了一个有趣和一致的多转对话。此外，语法纠错系统促进了用户语法技能的改进。因此，我们的系统支持基于角色对话的个性化学习，并使用语法错误反馈促进语法学习用户。此外，我们通过人类评估通过替换与NAO机器人的谈话来替换真正的人类，验证了FreeTalky是否提供了减轻卵杆菌的实际帮助。

本文报告了建立在线语言学习工具的进步，以通过使用对话系统作为对话实践伙伴为学习者提供对话体验。我们的系统可以随时适应用户的语言水平。我们还提供自动语法错误反馈，以帮助用户从错误中学习。根据我们的第一个采用者，我们的系统娱乐和有用。此外，我们将为学习技术社区提供有关语言学习和语法校正的大规模对话数据集。我们的下一步是通过使用强化学习算法使我们的系统更适应用户配置文件。

我们提出了Blenderbot 3，这是一个175B参数对话模型，能够通过访问Internet和长期内存进行开放域对话，并接受了大量用户定义的任务的培训。我们同时发布了模型权重和代码，还将模型部署在公共网页上，以与有机用户进行交互。该技术报告描述了该模型的构建方式（建筑，模型和培训计划）以及其部署的细节，包括安全机制。人类评估表明，它优于现有的开放域对话代理，包括其前身（Roller等，2021； Komeili等，2022）。最后，我们使用部署收集的数据详细介绍了持续学习的计划，该数据也将公开发布。因此，该研究计划的目标是使社区能够研究通过互动学习的不断改进的负责任的代理商。

In open-domain dialogue intelligent agents should exhibit the use of knowledge, however there are few convincing demonstrations of this to date. The most popular sequence to sequence models typically "generate and hope" generic utterances that can be memorized in the weights of the model when mapping from input utterance(s) to output, rather than employing recalled knowledge as context. Use of knowledge has so far proved difficult, in part because of the lack of a supervised learning benchmark task which exhibits knowledgeable open dialogue with clear grounding. To that end we collect and release a large dataset with conversations directly grounded with knowledge retrieved from Wikipedia. We then design architectures capable of retrieving knowledge, reading and conditioning on it, and finally generating natural responses. Our best performing dialogue models are able to conduct knowledgeable discussions on open-domain topics as evaluated by automatic metrics and human evaluations, while our new benchmark allows for measuring further improvements in this important research direction.

诸如说服力之类的复杂对话设置涉及交流态度或行为的变化，因此即使与主题没有直接相关，用户的观点也需要解决。在这项工作中，我们贡献了一个新颖的模块化对话系统框架，该框架将事实信息和社会内容无缝地整合到有说服力的对话中。我们的框架可以推广到任何混合社交和任务内容的对话任务。我们进行了一项研究，将用户对框架的评估与基线端到端生成模型进行了比较。我们发现，与没有明确处理社交内容或事实问题的端到端模型相比，我们的框架在包括能力和友善的各个方面更受欢迎。

在这项工作中，我们为数字教练提供了一个新的数据集和一种计算策略，旨在指导用户练习自我附加疗法的方案。我们的框架增强了基于规则的对话代理，具有深入学习分类器，可在用户的文本响应中识别潜在的情感，以及一种深入学习的辅助检索方法，用于制作新颖，流利和善解人意的话语。我们还制作了用户可以选择与之互动的类似人类的角色。我们的目标是在虚拟疗法课程中获得高水平的参与度。我们在n = 16名参与者的非临床试验中评估了我们的框架的有效性，在五天的时间里，所有人都至少与代理商进行了四次相互作用。我们发现，与简单的基于规则的框架相比，我们的平台在同理心，用户参与度和实用性方面的评分始终高。最后，我们提供指南，以根据收到的反馈来进一步改善应用程序的设计和性能。

最近十年表明，人们对机器人作为福祉教练的兴趣越来越大。但是，尚未提出针对机器人设计作为促进心理健康的教练的凝聚力和全面的准则。本文详细介绍了基于基于扎根理论方法的定性荟萃分析的设计和道德建议，该方法是通过三项以用户为中心的涉及机器人福祉教练的三个不同的以用户为中心进行的，即：（1）与参与性设计研究一起进行的。 11名参与者由两位潜在用户组成，他们与人类教练一起参加了简短的专注于解决方案的实践研究，以及不同学科的教练，（2）半结构化的个人访谈数据，这些数据来自20名参加积极心理学干预研究的参与者借助机器人福祉教练胡椒，（3）与3名积极心理学研究的参与者以及2名相关的福祉教练进行了一项参与式设计研究。在进行主题分析和定性荟萃分析之后，我们将收集到收敛性和不同主题的数据整理在一起，并从这些结果中提炼了一套设计准则和道德考虑。我们的发现可以在设计机器人心理福祉教练时考虑到关键方面的关键方面。

会话代理已成为简单任务允许情况的一般人群的组成部分。然而，这些系统尚未对各种和少数群体的任何社会影响，例如，帮助患有神经系统障碍的人，例如ALS和言语，语言和社交交流障碍的人。语言模型技术可以发挥巨大作用，以帮助这些用户进行日常沟通和社交互动。要启用此群体，我们构建了一个对话系统，可以使用CUES或关键字的用户控制。我们构建可以在用于控制响应生成的对话响应上下文中建立相关提示的模型，并可以加快通信。我们还介绍了一个关键字丢失来限制模型输出。我们在定性和定量上展示我们的模型可以有效地将关键字诱导到模型响应中，而不会降低响应的质量。在使用退行性障碍的人的使用情况的背景下，我们展示了对我们的提示或关键字预测器和可控对话系统的人类评估，并显示我们的模型比没有控制的模型更好地表现更好。我们的研究表明，在结束到结束响应生成模型的关键字控制是强大的，可以使用户能够与退行性疾病启用和赋予日常通信的日常沟通。

以任务为导向的对话系统（TODS）继续升高，因为各种行业发现有效地利用其能力，节省时间和金钱。然而，即使是最先进的TOD尚未达到其全部潜力。TOD通常具有主要设计专注于完成手头的任务，因此任务分辨率的度量应优先考虑。可能会忽略可能指向对话的其他可能指向成功或其他方面的会话质量属性。这可能导致人类和对话系统之间的相互作用，让用户不满意或沮丧。本文探讨了对话系统的评价框架的文献，以及对话系统中的会话质量属性的作用，看起来，如何以及在与对话系统的性能相关的情况下，如何相关。

Due to the lack of human resources for mental health support, there is an increasing demand for employing conversational agents for support. Recent work has demonstrated the effectiveness of dialogue models in providing emotional support. As previous studies have demonstrated that seekers' persona is an important factor for effective support, we investigate whether there are benefits to modeling such information in dialogue models for support. In this paper, our empirical analysis verifies that persona has an important impact on emotional support. Therefore, we propose a framework for dynamically inferring and modeling seekers' persona. We first train a model for inferring the seeker's persona from the conversation history. Accordingly, we propose PAL, a model that leverages persona information and, in conjunction with our strategy-based controllable generation method, provides personalized emotional support. Automatic and manual evaluations demonstrate that our proposed model, PAL, achieves state-of-the-art results, outperforming the baselines on the studied benchmark. Our code and data are publicly available at https://github.com/chengjl19/PAL.

BlenderBot 2.0是通过使用Internet搜索模块和多次会话来反映实时信息和记住用户信息来表示开放式聊天聊天的对话模型。尽管如此，模型仍然有改进的空间。为此，我们从三个角度检查了BlenderBot 2.0限制和错误：模型，数据和用户。从数据的角度来看，我们突出了在众包流程期间向工人提供的不明确指南，以及缺乏在收集的数据中炼制仇恨言论的过程，并验证基于互联网的信息的准确性。从用户的角度来看，我们确定了百分之九种类型的展示2.0问题，并彻底调查了它们的原因。此外，对于每个观点来说，提出了实际改进方法，我们讨论了几个潜在的未来研究方向。

The goal of building dialogue agents that can converse with humans naturally has been a long-standing dream of researchers since the early days of artificial intelligence. The well-known Turing Test proposed to judge the ultimate validity of an artificial intelligence agent on the indistinguishability of its dialogues from humans'. It should come as no surprise that human-level dialogue systems are very challenging to build. But, while early effort on rule-based systems found limited success, the emergence of deep learning enabled great advance on this topic. In this thesis, we focus on methods that address the numerous issues that have been imposing the gap between artificial conversational agents and human-level interlocutors. These methods were proposed and experimented with in ways that were inspired by general state-of-the-art AI methodologies. But they also targeted the characteristics that dialogue systems possess.

Any organization needs to improve their products, services, and processes. In this context, engaging with customers and understanding their journey is essential. Organizations have leveraged various techniques and technologies to support customer engagement, from call centres to chatbots and virtual agents. Recently, these systems have used Machine Learning (ML) and Natural Language Processing (NLP) to analyze large volumes of customer feedback and engagement data. The goal is to understand customers in context and provide meaningful answers across various channels. Despite multiple advances in Conversational Artificial Intelligence (AI) and Recommender Systems (RS), it is still challenging to understand the intent behind customer questions during the customer journey. To address this challenge, in this paper, we study and analyze the recent work in Conversational Recommender Systems (CRS) in general and, more specifically, in chatbot-based CRS. We introduce a pipeline to contextualize the input utterances in conversations. We then take the next step towards leveraging reverse feature engineering to link the contextualized input and learning model to support intent recognition. Since performance evaluation is achieved based on different ML models, we use transformer base models to evaluate the proposed approach using a labelled dialogue dataset (MSDialogue) of question-answering interactions between information seekers and answer providers.

大规模的语言技术越来越多地用于与人类在不同情况下的各种形式的交流中。这些技术的一种特殊用例是对话剂，它会根据提示和查询输出自然语言文本。这种参与方式提出了许多社会和道德问题。例如，将对话剂与人类规范或价值观相结合意味着什么？它们应该与哪些规范或价值观保持一致？如何实现这一目标？在本文中，我们提出了许多步骤来帮助回答这些问题。我们首先要对对话代理人和人类对话者之间语言交流的基础进行哲学分析。然后，我们使用此分析来识别和制定理想的对话规范，这些规范可以控制人类与对话代理之间的成功语言交流。此外，我们探讨了如何使用这些规范来使对话剂与在一系列不同的话语领域中的人类价值相结合。最后，我们讨论了我们对与这些规范和价值观一致的对话代理设计的建议的实际含义。

Automatic speech recognition (ASR) meets more informal and free-form input data as voice user interfaces and conversational agents such as the voice assistants such as Alexa, Google Home, etc., gain popularity. Conversational speech is both the most difficult and environmentally relevant sort of data for speech recognition. In this paper, we take a linguistic perspective, and take the French language as a case study toward disambiguation of the French homophones. Our contribution aims to provide more insight into human speech transcription accuracy in conditions to reproduce those of state-of-the-art ASR systems, although in a much focused situation. We investigate a case study involving the most common errors encountered in the automatic transcription of French language.

Conversational AI has become an increasingly prominent and practical application of machine learning. However, existing conversational AI techniques still suffer from various limitations. One such limitation is a lack of well-developed methods for incorporating auxiliary information that could help a model understand conversational context better. In this paper, we explore how persona-based information could help improve the quality of response generation in conversations. First, we provide a literature review focusing on the current state-of-the-art methods that utilize persona information. We evaluate two strong baseline methods, the Ranking Profile Memory Network and the Poly-Encoder, on the NeurIPS ConvAI2 benchmark dataset. Our analysis elucidates the importance of incorporating persona information into conversational systems. Additionally, our study highlights several limitations with current state-of-the-art methods and outlines challenges and future research directions for advancing personalized conversational AI technology.

使用良好形成的书面文本编译了当前可用的语法错误校正（GEC）数据集，将这些数据集的适用性限制为其他域，例如非正式的写作和对话框。在本文中，我们介绍了从开放式Chatbot对话中汲取的新颖平行GEC数据集;此数据集是我们的知识，将第一个GEC数据集定为会话设置。为了演示数据集的实用程序，我们使用注释的数据来微调最先进的GEC模型，从而提高了模型精度的16点。这在GEC模型中特别重要，因为模型精度被认为比GEC任务中的召回更重要，因为误报可能导致语言学习者的严重混乱。我们还提出了一个详细的注释方案，通过对可靠性的影响来排名错误，使我们的数据集两个可重复和可扩展。实验结果表明，我们的数据在提高了GEC模型性能方面的效果。

深度学习的最新进展，尤其是编码器架构的发明，已大大改善了抽象性摘要系统的性能。尽管大多数研究都集中在书面文件上，但我们观察到过去几年对对话和多方对话的总结越来越兴趣。一个可以可靠地将人类对话的音频或笔录转换为删节版本的系统，该版本在讨论中最重要的一点上可以在各种现实世界中，从商务会议到医疗咨询再到客户都有价值服务电话。本文着重于多党会议的抽象性摘要，对与此任务相关的挑战，数据集和系统进行了调查，并讨论了未来研究的有希望的方向。

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.

在最近的工作中已显示出一种模式指导的对话管理方法，可以有效地创建能够充当友好同行或任务助理的强大定制虚拟代理。但是，这些方法在开放式，混合初始性领域中的成功应用仍然难以捉摸 - 尤其是在诸如虚拟标准化患者之类的医疗领域，在这种复杂的互动很常见的情况下 - 比以前的系统需要更广泛，更灵活的对话管理能力提供。在本文中，我们描述了用于开发索菲（Sophie）的通用架构指导的对话管理框架，Sophie是一种虚拟标准化的癌症患者，可让医生方便地练习与患者的互动。我们对医学生和索菲之间的对话进行了众包评估。我们的经纪人被认为是自然，情感上适当的反应，并且与她作为癌症患者的角色一致。此外，它大大优于对人类标准化患者语料库进行微调的端到端神经模型，这证明了模式引导方法的优势。
