Recent advances in AI and ML applications have benefited from rapid progress in NLP research. Leaderboards have emerged as a popular mechanism to track and accelerate progress in NLP through competitive model development. While this has increased interest and participation, the over-reliance on single, and accuracy-based metrics have shifted focus from other important metrics that might be equally pertinent to consider in real-world contexts. In this paper, we offer a preliminary discussion of the risks associated with focusing exclusively on accuracy metrics and draw on recent discussions to highlight prescriptive suggestions on how to develop more practical and effective leaderboards that can better reflect the real-world utility of models.

AI中的不同子场倾向于储存一小部分有影响力的基准。这些基准作为一系列涂抹的常见问题的支架运作，这些常见问题经常被录制为朝向灵活和更广泛的AI系统的道路上的基础里程碑。这些基准最先进的性能被广泛理解为表明对这些长期目标的进展。在这个位置纸中，我们探讨了这种基准的限制，以便在其框架中揭示构建有效性问题，作为功能“一般”的进展措施，他们被设置为。

This paper presents the OPUS ecosystem with a focus on the development of open machine translation models and tools, and their integration into end-user applications, development platforms and professional workflows. We discuss our on-going mission of increasing language coverage and translation quality, and also describe on-going work on the development of modular translation models and speed-optimized compact solutions for real-time translation on regular desktops and small devices.

With the fast development of Machine Translation (MT) systems, especially the new boost from Neural MT (NMT) models, the MT output quality has reached a new level of accuracy. However, many researchers criticised that the current popular evaluation metrics such as BLEU can not correctly distinguish the state-of-the-art NMT systems regarding quality differences. In this short paper, we describe the design and implementation of a linguistically motivated human-in-the-loop evaluation metric looking into idiomatic and terminological Multi-word Expressions (MWEs). MWEs have played a bottleneck in many Natural Language Processing (NLP) tasks including MT. MWEs can be used as one of the main factors to distinguish different MT systems by looking into their capabilities in recognising and translating MWEs in an accurate and meaning equivalent manner.

The rapid growth of machine translation (MT) systems has necessitated comprehensive studies to meta-evaluate evaluation metrics being used, which enables a better selection of metrics that best reflect MT quality. Unfortunately, most of the research focuses on high-resource languages, mainly English, the observations for which may not always apply to other languages. Indian languages, having over a billion speakers, are linguistically different from English, and to date, there has not been a systematic study of evaluating MT systems from English into Indian languages. In this paper, we fill this gap by creating an MQM dataset consisting of 7000 fine-grained annotations, spanning 5 Indian languages and 7 MT systems, and use it to establish correlations between annotator scores and scores obtained using existing automatic metrics. Our results show that pre-trained metrics, such as COMET, have the highest correlations with annotator scores. Additionally, we find that the metrics do not adequately capture fluency-based errors in Indian languages, and there is a need to develop metrics focused on Indian languages. We hope that our dataset and analysis will help promote further research in this area.

由于它们的低准确性，透明度缺乏透明度，而不是语义，而不是语义，而不是语言技能，而不是语义，而且与人类质量评估的普遍挑剔，机器翻译的传统自动评估度量被语言学家被广泛批评。 MQM样记录形式的人类评估始终是客户和翻译服务提供商（TSP）的真实行业环境中进行的。然而，传统的人类翻译质量评估昂贵才能实现和进入伟大的语言细节，提出对帧间可靠性（IRR）的问题，并且不设计用于衡量比优质质量翻译更糟糕的质量。在这项工作中，我们介绍了希望，基于专业后编辑注释的机器翻译输出的主导和以人为际的评估框架。它仅包含有限数量的常见错误类型，并使用评分模型与错误惩罚点（EPP）的几何进度反映了每个转换单元的错误严重性级别。来自高技术域的英语语言对MT输出的初始实验工作来自高技术领域的营销内容类型的文本揭示了我们的评估框架在反映了关于整体系统级性能和段级透明度的MT输出质量方面非常有效，并且它会增加错误类型解释。该方法具有若干关键优势，例如测量和比较少于不同系统的完美MT输出的能力，表明人类对质量的能力，立即估算所需的劳动力估算，使MT输出到优质的质量，低成本和更快的应用，以及更高的IRR。我们的实验数据可用于\ url {https://github.com/lhan87/hope}。

The primary obstacle to developing technologies for low-resource languages is the lack of representative, usable data. In this paper, we report the deployment of technology-driven data collection methods for creating a corpus of more than 60,000 translations from Hindi to Gondi, a low-resource vulnerable language spoken by around 2.3 million tribal people in south and central India. During this process, we help expand information access in Gondi across 2 different dimensions (a) The creation of linguistic resources that can be used by the community, such as a dictionary, children's stories, Gondi translations from multiple sources and an Interactive Voice Response (IVR) based mass awareness platform; (b) Enabling its use in the digital domain by developing a Hindi-Gondi machine translation model, which is compressed by nearly 4 times to enable it's edge deployment on low-resource edge devices and in areas of little to no internet connectivity. We also present preliminary evaluations of utilizing the developed machine translation model to provide assistance to volunteers who are involved in collecting more data for the target language. Through these interventions, we not only created a refined and evaluated corpus of 26,240 Hindi-Gondi translations that was used for building the translation model but also engaged nearly 850 community members who can help take Gondi onto the internet.

Automatic machine translation (MT) metrics are widely used to distinguish the translation qualities of machine translation systems across relatively large test sets (system-level evaluation). However, it is unclear if automatic metrics are reliable at distinguishing good translations from bad translations at the sentence level (segment-level evaluation). In this paper, we investigate how useful MT metrics are at detecting the success of a machine translation component when placed in a larger platform with a downstream task. We evaluate the segment-level performance of the most widely used MT metrics (chrF, COMET, BERTScore, etc.) on three downstream cross-lingual tasks (dialogue state tracking, question answering, and semantic parsing). For each task, we only have access to a monolingual task-specific model. We calculate the correlation between the metric's ability to predict a good/bad translation with the success/failure on the final task for the Translate-Test setup. Our experiments demonstrate that all metrics exhibit negligible correlation with the extrinsic evaluation of the downstream outcomes. We also find that the scores provided by neural metrics are not interpretable mostly because of undefined ranges. Our analysis suggests that future MT metrics be designed to produce error labels rather than scores to facilitate extrinsic evaluation.

Natural Language Generation (NLG) has improved exponentially in recent years thanks to the development of sequence-to-sequence deep learning technologies such as Transformer-based language models. This advancement has led to more fluent and coherent NLG, leading to improved development in downstream tasks such as abstractive summarization, dialogue generation and data-to-text generation. However, it is also apparent that deep learning based generation is prone to hallucinate unintended text, which degrades the system performance and fails to meet user expectations in many real-world scenarios. To address this issue, many studies have been presented in measuring and mitigating hallucinated texts, but these have never been reviewed in a comprehensive manner before. In this survey, we thus provide a broad overview of the research progress and challenges in the hallucination problem in NLG. The survey is organized into two parts: (1) a general overview of metrics, mitigation methods, and future directions; and (2) an overview of task-specific research progress on hallucinations in the following downstream tasks, namely abstractive summarization, dialogue generation, generative question answering, data-to-text generation, machine translation, and visual-language generation. This survey serves to facilitate collaborative efforts among researchers in tackling the challenge of hallucinated texts in NLG.

语言可以用作再现和执行有害刻板印象和偏差的手段，并被分析在许多研究中。在本文中，我们对自然语言处理中的性别偏见进行了304篇论文。我们分析了社会科学中性别及其类别的定义，并将其连接到NLP研究中性别偏见的正式定义。我们调查了在对性别偏见的研究中应用的Lexica和数据集，然后比较和对比方法来检测和减轻性别偏见。我们发现对性别偏见的研究遭受了四个核心限制。 1）大多数研究将性别视为忽视其流动性和连续性的二元变量。 2）大部分工作都在单机设置中进行英语或其他高资源语言进行。 3）尽管在NLP方法中对性别偏见进行了无数的论文，但我们发现大多数新开发的算法都没有测试他们的偏见模型，并无视他们的工作的伦理考虑。 4）最后，在这一研究线上发展的方法基本缺陷涵盖性别偏差的非常有限的定义，缺乏评估基线和管道。我们建议建议克服这些限制作为未来研究的指导。

Automatic sign language processing is gaining popularity in Natural Language Processing (NLP) research (Yin et al., 2021). In machine translation (MT) in particular, sign language translation based on glosses is a prominent approach. In this paper, we review recent works on neural gloss translation. We find that limitations of glosses in general and limitations of specific datasets are not discussed in a transparent manner and that there is no common standard for evaluation. To address these issues, we put forward concrete recommendations for future research on gloss translation. Our suggestions advocate awareness of the inherent limitations of gloss-based approaches, realistic datasets, stronger baselines and convincing evaluation.

机器翻译系统（MTS）是通过将文本或语音从一种语言转换为另一种语言的有效工具。在像印度这样的大型多语言环境中，对有效的翻译系统的需求变得显而易见，英语和一套印度语言（ILS）正式使用。与英语相反，由于语料库的不可用，IL仍然被视为低资源语言。为了解决不对称性质，多语言神经机器翻译（MNMT）系统会发展为在这个方向上的理想方法。在本文中，我们提出了一个MNMT系统，以解决与低资源语言翻译有关的问题。我们的模型包括两个MNMT系统，即用于英语印度（一对多），另一个用于指示英语（多一对多），其中包含15个语言对（30个翻译说明）的共享编码器码头。由于大多数IL对具有很少的平行语料库，因此不足以训练任何机器翻译模型。我们探索各种增强策略，以通过建议的模型提高整体翻译质量。最先进的变压器体系结构用于实现所提出的模型。大量数据的试验揭示了其优越性比常规模型的优势。此外，本文解决了语言关系的使用（在方言，脚本等方面），尤其是关于同一家族的高资源语言在提高低资源语言表现方面的作用。此外，实验结果还表明了ILS的倒退和域适应性的优势，以提高源和目标语言的翻译质量。使用所有这些关键方法，我们提出的模型在评估指标方面比基线模型更有效，即一组ILS的BLEU（双语评估研究）得分。

自然语言处理研究人员已经确定了对生成任务的评估方法的局限性，具有新的问题，提出了自动指标和人群判断的有效性。同时，改善生成模型的努力倾向于专注于简单的n-gram重叠度量（例如，Bleu，Rouge）。我们认为，对模型和指标的新进展应该每个人都更直接受益并告知另一个。因此，我们提出了排行榜，竞争排行榜（广告牌）的概括，同时跟踪语言生成任务和指标的进展。与通过预定度量分类提交系统的传统的单向排行榜不同，广告牌可接受发电机和评估度量作为竞争条目。广告牌会自动创建一个基于跨发电机的全局分析选择和线性地组合一些指标的集合度量。此外，指标基于与人类判断的相关性进行排序。我们释放了用于机器翻译，摘要和图像标题的四个广告牌。我们展示了一些多样化度量的线性集合有时会在隔离中显着优于现有的度量。我们的混合效果模型分析表明，大多数自动度量，尤其是基于参考的机器，对人类发电的重估，展示了更新度量的重要性，将来变得更强大（也许与人类更相似）。

原型NLP实验训练了标记为英语数据的标准体系结构，并优化了准确性，而无需考虑其他方面，例如公平，解释性或计算效率。我们通过最近对NLP研究论文的手动分类表明，确实是这种情况，并将其称为正方形的实验设置。我们观察到，NLP研究通常超出了一个平方的设置，例如，不仅关注准确性，而且关注公平或解释性，而且通常仅沿着单个维度。例如，针对多语言的大多数工作仅考虑准确性；大多数关于公平或解释性的工作仅考虑英语；等等。我们通过对最近的NLP研究论文和ACL测试奖励获得者的手动分类来展示此信息。大多数研究的这种一维意味着我们只探索NLP研究搜索空间的一部分。我们提供了一个历史和最新示例，说明了一个偏见如何导致研究人员得出错误的结论或做出不明智的选择，指出了在研究歧管上有希望但未开发的方向，并提出实用的建议以实现更多的多维研究。我们打开注释的结果，以启用https://github.com/google-research/url-nlp的进一步分析

Given a document in a source language, cross-lingual summarization (CLS) aims at generating a concise summary in a different target language. Unlike monolingual summarization (MS), naturally occurring source-language documents paired with target-language summaries are rare. To collect large-scale CLS samples, existing datasets typically involve translation in their creation. However, the translated text is distinguished from the text originally written in that language, i.e., translationese. Though many efforts have been devoted to CLS, none of them notice the phenomenon of translationese. In this paper, we first confirm that the different approaches to constructing CLS datasets will lead to different degrees of translationese. Then we design systematic experiments to investigate how translationese affects CLS model evaluation and performance when it appears in source documents or target summaries. In detail, we find that (1) the translationese in documents or summaries of test sets might lead to the discrepancy between human judgment and automatic evaluation; (2) the translationese in training sets would harm model performance in the real scene; (3) though machine-translated documents involve translationese, they are very useful for building CLS systems on low-resource languages under specific training strategies. Furthermore, we give suggestions for future CLS research including dataset and model developments. We hope that our work could let researchers notice the phenomenon of translationese in CLS and take it into account in the future.

两个关键假设塑造了排名检索的通常视图：（1）搜索者可以为他们希望看到的文档中的疑问选择单词，并且（2）排名检索的文档就足以，因为搜索者将足够就足够了能够认识到他们希望找到的那些。当要搜索的文档处于搜索者未知的语言时，既不是真的。在这种情况下，需要跨语言信息检索（CLIR）。本章审查了艺术技术的交流信息检索，并概述了一些开放的研究问题。

同时语音转换（Simulst）是必须在部分，增量语音输入上执行输出生成的任务。近年来，由于交叉语言应用场景的传播，如国际现场会议和流媒体讲座，Sumulst已经变得很受欢迎，因为在飞行的语音翻译中可以促进用户访问视听内容。在本文中，我们分析到目前为止所开发的Simulst系统的特征，讨论其优势和缺点。然后我们专注于正确评估系统效率所需的评估框架。为此，我们提高了更广泛的性能分析的需求，还包括用户体验的角度。实际上，Simulst Systems不仅应在质量/延迟措施方面进行评估，而且还可以通过以任务为导向的指标计费，例如，用于所采用的可视化策略。鉴于此，我们突出了社区实现的目标以及仍然缺少的目标。

Grammatical Error Correction (GEC) is the task of automatically detecting and correcting errors in text. The task not only includes the correction of grammatical errors, such as missing prepositions and mismatched subject-verb agreement, but also orthographic and semantic errors, such as misspellings and word choice errors respectively. The field has seen significant progress in the last decade, motivated in part by a series of five shared tasks, which drove the development of rule-based methods, statistical classifiers, statistical machine translation, and finally neural machine translation systems which represent the current dominant state of the art. In this survey paper, we condense the field into a single article and first outline some of the linguistic challenges of the task, introduce the most popular datasets that are available to researchers (for both English and other languages), and summarise the various methods and techniques that have been developed with a particular focus on artificial error generation. We next describe the many different approaches to evaluation as well as concerns surrounding metric reliability, especially in relation to subjective human judgements, before concluding with an overview of recent progress and suggestions for future work and remaining challenges. We hope that this survey will serve as comprehensive resource for researchers who are new to the field or who want to be kept apprised of recent developments.

In this chapter, we review and discuss the transformation of AI technology in HCI/UX work and assess how AI technology will change how we do the work. We first discuss how AI can be used to enhance the result of user research and design evaluation. We then discuss how AI technology can be used to enhance HCI/UX design. Finally, we discuss how AI-enabled capabilities can improve UX when users interact with computing systems, applications, and services.

As machine translation (MT) metrics improve their correlation with human judgement every year, it is crucial to understand the limitations of such metrics at the segment level. Specifically, it is important to investigate metric behaviour when facing accuracy errors in MT because these can have dangerous consequences in certain contexts (e.g., legal, medical). We curate ACES, a translation accuracy challenge set, consisting of 68 phenomena ranging from simple perturbations at the word/character level to more complex errors based on discourse and real-world knowledge. We use ACES to evaluate a wide range of MT metrics including the submissions to the WMT 2022 metrics shared task and perform several analyses leading to general recommendations for metric developers. We recommend: a) combining metrics with different strengths, b) developing metrics that give more weight to the source and less to surface-level overlap with the reference and c) explicitly modelling additional language-specific information beyond what is available via multilingual embeddings.
