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。

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.

语言教学的挑战之一是如何以有意义的方式组织有关语言语法的规则。这不仅需要教学技能,而且还需要对该语言有深刻的了解。虽然开发此类课程的综合材料以英语和一些广泛的语言提供,但对于许多其他语言,教师需要手动创建它们来满足学生的需求。这个过程具有挑战性,因为i)要求这样的专家可以访问并拥有必要的资源,ii)即使有这样的专家,描述了一种语言的所有复杂性,这是耗时的,容易出现遗漏。在本文中,我们提出了一个自动框架,旨在通过自动发现和可视化语法各个方面的描述来促进这一过程。具体而言,我们从自然文本语料库中提取描述,该语料库回答有关形态句法(学习单词顺序,协议,案例标记或单词形成)和语义(学习词汇的学习)的问题,并显示了说明性示例。我们将这种方法用于教授印度语言,卡纳达语和马拉地语,这些方法与英语不同,它们没有发达的教学资源,因此很可能会从这项练习中受益。为了评估提取材料的感知效用,我们获得了北美学校的语言教育者的帮助,这些教育者教这些语言进行手动评估。总体而言,教师认为这些材料是他们自己的课程准备甚至学习者评估的参考材料有趣的。

This paper presents the development of an AI-based language learning platform Revita. It is a freely available intelligent online tutor, developed to support learners of multiple languages, from low-intermediate to advanced levels. It has been in pilot use by hundreds of students at several universities, whose feedback and needs are shaping the development. One of the main emerging features of Revita is the introduction of a system of linguistic constructs as the representation of domain knowledge. The system of constructs is developed in close collaboration with experts in language teaching. Constructs define the types of exercises, the content of the feedback, and enable the detailed modeling and evaluation of learning progress.

When beginners learn to speak a non-native language, it is difficult for them to judge for themselves whether they are speaking well. Therefore, computer-assisted pronunciation training systems are used to detect learner mispronunciations. These systems typically compare the user's speech with that of a specific native speaker as a model in units of rhythm, phonemes, or words and calculate the differences. However, they require extensive speech data with detailed annotations or can only compare with one specific native speaker. To overcome these problems, we propose a new language learning support system that calculates speech scores and detects mispronunciations by beginners based on a small amount of unannotated speech data without comparison to a specific person. The proposed system uses deep learning--based speech processing to display the pronunciation score of the learner's speech and the difference/distance between the learner's and a group of models' pronunciation in an intuitively visual manner. Learners can gradually improve their pronunciation by eliminating differences and shortening the distance from the model until they become sufficiently proficient. Furthermore, since the pronunciation score and difference/distance are not calculated compared to specific sentences of a particular model, users are free to study the sentences they wish to study. We also built an application to help non-native speakers learn English and confirmed that it can improve users' speech intelligibility.

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。

对话研究的最终目标是开发可以在交互式设置中有效使用的系统。为此,我们在第9对话系统技术挑战中介绍了对话框的交互式评估。该曲目由两个子任务组成。第一个子任务涉及建立知识接地的响应生成模型。第二个子任务旨在通过与真实用户的交互式设置进行评估,旨在将对话模型扩展到静态数据集之外。我们的曲目挑战参与者开发强大的响应生成模型,并探索将它们扩展到与真实用户的来回互动的策略。从静态语料库到交互式评估的发展引入了独特的挑战,并促进了对开放域对话系统的更全面评估。本文概述了曲目,包括方法和结果。此外,它提供了有关如何最佳评估开放域对话框模型的见解

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。

Incivility remains a major challenge for online discussion platforms, to such an extent that even conversations between well-intentioned users can often derail into uncivil behavior. Traditionally, platforms have relied on moderators to -- with or without algorithmic assistance -- take corrective actions such as removing comments or banning users. In this work we propose a complementary paradigm that directly empowers users by proactively enhancing their awareness about existing tension in the conversation they are engaging in and actively guides them as they are drafting their replies to avoid further escalation. As a proof of concept for this paradigm, we design an algorithmic tool that provides such proactive information directly to users, and conduct a user study in a popular discussion platform. Through a mixed methods approach combining surveys with a randomized controlled experiment, we uncover qualitative and quantitative insights regarding how the participants utilize and react to this information. Most participants report finding this proactive paradigm valuable, noting that it helps them to identify tension that they may have otherwise missed and prompts them to further reflect on their own replies and to revise them. These effects are corroborated by a comparison of how the participants draft their reply when our tool warns them that their conversation is at risk of derailing into uncivil behavior versus in a control condition where the tool is disabled. These preliminary findings highlight the potential of this user-centered paradigm and point to concrete directions for future implementations.

Charisma is considered as one's ability to attract and potentially also influence others. Clearly, there can be considerable interest from an artificial intelligence's (AI) perspective to provide it with such skill. Beyond, a plethora of use cases opens up for computational measurement of human charisma, such as for tutoring humans in the acquisition of charisma, mediating human-to-human conversation, or identifying charismatic individuals in big social data. A number of models exist that base charisma on various dimensions, often following the idea that charisma is given if someone could and would help others. Examples include influence (could help) and affability (would help) in scientific studies or power (could help), presence, and warmth (both would help) as a popular concept. Modelling high levels in these dimensions for humanoid robots or virtual agents, seems accomplishable. Beyond, also automatic measurement appears quite feasible with the recent advances in the related fields of Affective Computing and Social Signal Processing. Here, we, thereforem present a blueprint for building machines that can appear charismatic, but also analyse the charisma of others. To this end, we first provide the psychological perspective including different models of charisma and behavioural cues of it. We then switch to conversational charisma in spoken language as an exemplary modality that is essential for human-human and human-computer conversations. The computational perspective then deals with the recognition and generation of charismatic behaviour by AI. This includes an overview of the state of play in the field and the aforementioned blueprint. We then name exemplary use cases of computational charismatic skills before switching to ethical aspects and concluding this overview and perspective on building charisma-enabled AI.
