Many machine learning algorithms have been developed in recent years to enhance the performance of a model in different aspects of artificial intelligence. But the problem persists due to inadequate data and resources. Integrating knowledge in a machine learning model can help to overcome these obstacles up to a certain degree. Incorporating knowledge is a complex task though because of various forms of knowledge representation. In this paper, we will give a brief overview of these different forms of knowledge integration and their performance in certain machine learning tasks.

Deep learning models, though having achieved great success in many different fields over the past years, are usually data hungry, fail to perform well on unseen samples, and lack of interpretability. Various prior knowledge often exists in the target domain and their use can alleviate the deficiencies with deep learning. To better mimic the behavior of human brains, different advanced methods have been proposed to identify domain knowledge and integrate it into deep models for data-efficient, generalizable, and interpretable deep learning, which we refer to as knowledge-augmented deep learning (KADL). In this survey, we define the concept of KADL, and introduce its three major tasks, i.e., knowledge identification, knowledge representation, and knowledge integration. Different from existing surveys that are focused on a specific type of knowledge, we provide a broad and complete taxonomy of domain knowledge and its representations. Based on our taxonomy, we provide a systematic review of existing techniques, different from existing works that survey integration approaches agnostic to taxonomy of knowledge. This survey subsumes existing works and offers a bird's-eye view of research in the general area of knowledge-augmented deep learning. The thorough and critical reviews of numerous papers help not only understand current progresses but also identify future directions for the research on knowledge-augmented deep learning.

Neural-symbolic computing (NeSy), which pursues the integration of the symbolic and statistical paradigms of cognition, has been an active research area of Artificial Intelligence (AI) for many years. As NeSy shows promise of reconciling the advantages of reasoning and interpretability of symbolic representation and robust learning in neural networks, it may serve as a catalyst for the next generation of AI. In the present paper, we provide a systematic overview of the important and recent developments of research on NeSy AI. Firstly, we introduce study history of this area, covering early work and foundations. We further discuss background concepts and identify key driving factors behind the development of NeSy. Afterward, we categorize recent landmark approaches along several main characteristics that underline this research paradigm, including neural-symbolic integration, knowledge representation, knowledge embedding, and functionality. Then, we briefly discuss the successful application of modern NeSy approaches in several domains. Finally, we identify the open problems together with potential future research directions. This survey is expected to help new researchers enter this rapidly-developing field and accelerate progress towards data-and knowledge-driven AI.

我们提出了一种调查，其中在构建具有神经网络的模型时包括现有科学知识的方式。纳入领域知识不仅仅是构建科学助理，而且还有许多其他领域，涉及使用人机协作了解数据的其他领域。在许多这样的情况下，基于机器的模型结构可以显着地利用具有以足够精确的形式编码的域的人人类知识。本文审查了通过更改的域名知识：输入，丢失功能和深网络的架构。分类是为了便于阐述：在实践中，我们预计将采用这种变化的组合。在每个类别中，我们描述了所显示的技术，以产生深度神经网络性能的显着变化。

近年来，随着新颖的策略和应用，神经网络一直在迅速扩展。然而，尽管不可避免地会针对关键应用程序来解决这些挑战，例如神经网络技术诸如神经网络技术中仍未解决诸如神经网络技术的挑战。已经尝试通过用符号表示来表示和嵌入域知识来克服神经网络计算中的挑战。因此，出现了神经符号学习（Nesyl）概念，其中结合了符号表示的各个方面，并将常识带入神经网络（Nesyl）。在可解释性，推理和解释性至关重要的领域中，例如视频和图像字幕，提问和推理，健康信息学和基因组学，Nesyl表现出了有希望的结果。这篇综述介绍了一项有关最先进的Nesyl方法的全面调查，其原理，机器和深度学习算法的进步，诸如Opthalmology之类的应用以及最重要的是该新兴领域的未来观点。

主张神经符号人工智能（NESY）断言，将深度学习与象征性推理相结合将导致AI更强大，而不是本身。像深度学习一样成功，人们普遍认为，即使我们最好的深度学习系统也不是很擅长抽象推理。而且，由于推理与语言密不可分，因此具有直觉的意义，即自然语言处理（NLP）将成为NESY特别适合的候选人。我们对实施NLP实施NESY的研究进行了结构化审查，目的是回答Nesy是否确实符合其承诺的问题：推理，分布概括，解释性，学习和从小数据的可转让性以及新的推理到新的域。我们研究了知识表示的影响，例如规则和语义网络，语言结构和关系结构，以及隐式或明确的推理是否有助于更高的承诺分数。我们发现，将逻辑编译到神经网络中的系统会导致满足最NESY的目标，而其他因素（例如知识表示或神经体系结构的类型）与实现目标没有明显的相关性。我们发现在推理的定义方式上，特别是与人类级别的推理有关的许多差异，这会影响有关模型架构的决策并推动结论，这些结论在整个研究中并不总是一致的。因此，我们倡导采取更加有条不紊的方法来应用人类推理的理论以及适当的基准的发展，我们希望这可以更好地理解该领域的进步。我们在GitHub上提供数据和代码以进行进一步分析。

机器学习方法尤其是深度神经网络取得了巨大的成功，但其中许多往往依赖于一些标记的样品进行训练。在真实世界的应用中，我们经常需要通过例如具有新兴预测目标和昂贵的样本注释的动态上下文来解决样本短缺。因此，低资源学习，旨在学习具有足够资源（特别是培训样本）的强大预测模型，现在正在被广泛调查。在所有低资源学习研究中，许多人更喜欢以知识图（kg）的形式利用一些辅助信息，这对于知识表示变得越来越受欢迎，以减少对标记样本的依赖。在这项调查中，我们非常全面地审查了90美元的报纸关于两个主要的低资源学习设置 - 零射击学习（ZSL）的预测，从未出现过训练，而且很少拍摄的学习（FSL）预测的新类仅具有可用的少量标记样本。我们首先介绍了ZSL和FSL研究中使用的KGS以及现有的和潜在的KG施工解决方案，然后系统地分类和总结了KG感知ZSL和FSL方法，将它们划分为不同的范例，例如基于映射的映射，数据增强，基于传播和基于优化的。我们接下来呈现了不同的应用程序，包括计算机视觉和自然语言处理中的kg增强预测任务，还包括kg完成的任务，以及每个任务的一些典型评估资源。我们最终讨论了一些关于新学习和推理范式的方面的一些挑战和未来方向，以及高质量的KGs的建设。

全球DataSphere快速增加，预计将达到20251年的175个Zettabytes。但是，大多数内容都是非结构化的，并且无法通过机器可以理解。将此数据构建到知识图中，使得智能应用程序具有诸如深度问题的智能应用，推荐系统，语义搜索等。知识图是一种新兴技术，允许使用内容与上下文一起逻辑推理和揭示新的洞察。因此，它提供了必要的语法和推理语义，使得能够解决复杂的医疗保健，安全，金融机构，经济学和业务问题。作为一项结果，企业正在努力建设和维护知识图表，以支持各种下游应用。手动方法太贵了。自动化方案可以降低建设知识图的成本，高达15-250次。本文批评了最先进的自动化技术，以自主地生成近乎人类的近乎人类的质量。此外，它突出了需要解决的不同研究问题，以提供高质量的知识图表

事实证明，信息提取方法可有效从结构化或非结构化数据中提取三重。以（头部实体，关系，尾部实体）形式组织这样的三元组的组织称为知识图（kgs）。当前的大多数知识图都是不完整的。为了在下游任务中使用kgs，希望预测kgs中缺少链接。最近，通过将实体和关系嵌入到低维的矢量空间中，旨在根据先前访问的三元组来预测三元组，从而对KGS表示不同的方法。根据如何独立或依赖对三元组进行处理，我们将知识图完成的任务分为传统和图形神经网络表示学习，并更详细地讨论它们。在传统的方法中，每个三重三倍将独立处理，并在基于GNN的方法中进行处理，三倍也考虑了他们的当地社区。查看全文

Relational machine learning studies methods for the statistical analysis of relational, or graph-structured, data. In this paper, we provide a review of how such statistical models can be "trained" on large knowledge graphs, and then used to predict new facts about the world (which is equivalent to predicting new edges in the graph). In particular, we discuss two fundamentally different kinds of statistical relational models, both of which can scale to massive datasets. The first is based on latent feature models such as tensor factorization and multiway neural networks. The second is based on mining observable patterns in the graph. We also show how to combine these latent and observable models to get improved modeling power at decreased computational cost. Finally, we discuss how such statistical models of graphs can be combined with text-based information extraction methods for automatically constructing knowledge graphs from the Web. To this end, we also discuss Google's Knowledge Vault project as an example of such combination.

自动问题应答（QA）系统的目的是以时间有效的方式向用户查询提供答案。通常在数据库（或知识库）或通常被称为语料库的文件集合中找到答案。在过去的几十年里，收购知识的扩散，因此生物医学领域的新科学文章一直是指数增长。因此，即使对于领域专家，也难以跟踪域中的所有信息。随着商业搜索引擎的改进，用户可以在某些情况下键入其查询并获得最相关的一小组文档，以及在某些情况下从文档中的相关片段。但是，手动查找所需信息或答案可能仍然令人疑惑和耗时。这需要开发高效的QA系统，该系统旨在为用户提供精确和精确的答案提供了生物医学领域的自然语言问题。在本文中，我们介绍了用于开发普通域QA系统的基本方法，然后彻底调查生物医学QA系统的不同方面，包括使用结构化数据库和文本集合的基准数据集和几种提出的方​​法。我们还探讨了当前系统的局限性，并探索潜在的途径以获得进一步的进步。

内容的离散和连续表示（例如，语言或图像）具有有趣的属性，以便通过机器的理解或推理此内容来探索或推理。该职位论文提出了我们关于离散和持续陈述的作用及其在深度学习领域的作用的意见。目前的神经网络模型计算连续值数据。信息被压缩成密集，分布式嵌入式。通过Stark对比，人类在他们的语言中使用离散符号。此类符号代表了来自共享上下文信息的含义的世界的压缩版本。此外，人工推理涉及在认知水平处符号操纵，这促进了抽象的推理，知识和理解的构成，泛化和高效学习。通过这些见解的动机，在本文中，我们认为，结合离散和持续的陈述及其处理对于构建展示一般情报形式的系统至关重要。我们建议并讨论了几个途径，可以在包含离散元件来结合两种类型的陈述的优点来改进当前神经网络。

Knowledge graph (KG) embedding is to embed components of a KG including entities and relations into continuous vector spaces, so as to simplify the manipulation while preserving the inherent structure of the KG. It can benefit a variety of downstream tasks such as KG completion and relation extraction, and hence has quickly gained massive attention. In this article, we provide a systematic review of existing techniques, including not only the state-of-the-arts but also those with latest trends. Particularly, we make the review based on the type of information used in the embedding task. Techniques that conduct embedding using only facts observed in the KG are first introduced. We describe the overall framework, specific model design, typical training procedures, as well as pros and cons of such techniques. After that, we discuss techniques that further incorporate additional information besides facts. We focus specifically on the use of entity types, relation paths, textual descriptions, and logical rules. Finally, we briefly introduce how KG embedding can be applied to and benefit a wide variety of downstream tasks such as KG completion, relation extraction, question answering, and so forth.

外部知识（A.K.A.侧面信息）在零拍摄学习（ZSL）中起着关键作用，该角色旨在预测从未出现在训练数据中的看不见的类。已被广泛调查了几种外部知识，例如文本和属性，但他们独自受到不完整的语义。因此，一些最近的研究提出了由于其高度富有效力和代表知识的兼容性而使用知识图表（千克）。但是，ZSL社区仍然缺乏用于学习和比较不同外部知识设置和基于不同的KG的ZSL方法的标准基准。在本文中，我们提出了六个资源，涵盖了三个任务，即零拍摄图像分类（ZS-IMGC），零拍摄关系提取（ZS-RE）和零拍KG完成（ZS-KGC）。每个资源都有一个正常的zsl基准标记和包含从文本到属性的kg的kg，从关系知识到逻辑表达式。我们已清楚地介绍了这些资源，包括其建设，统计数据格式和使用情况W.r.t.不同的ZSL方法。更重要的是，我们进行了一项全面的基准研究，具有两个通用和最先进的方法，两种特定方法和一种可解释方法。我们讨论并比较了不同的ZSL范式W.R.T.不同的外部知识设置，并发现我们的资源具有开发更高级ZSL方法的巨大潜力，并为应用KGS进行增强机学习的更多解决方案。所有资源都可以在https://github.com/china-uk-zsl/resources_for_kzsl上获得。

Natural Language Processing (NLP) has been revolutionized by the use of Pre-trained Language Models (PLMs) such as BERT. Despite setting new records in nearly every NLP task, PLMs still face a number of challenges including poor interpretability, weak reasoning capability, and the need for a lot of expensive annotated data when applied to downstream tasks. By integrating external knowledge into PLMs, \textit{\underline{K}nowledge-\underline{E}nhanced \underline{P}re-trained \underline{L}anguage \underline{M}odels} (KEPLMs) have the potential to overcome the above-mentioned limitations. In this paper, we examine KEPLMs systematically through a series of studies. Specifically, we outline the common types and different formats of knowledge to be integrated into KEPLMs, detail the existing methods for building and evaluating KEPLMS, present the applications of KEPLMs in downstream tasks, and discuss the future research directions. Researchers will benefit from this survey by gaining a quick and comprehensive overview of the latest developments in this field.

Recent progress in artificial intelligence (AI) has renewed interest in building systems that learn and think like people. Many advances have come from using deep neural networks trained end-to-end in tasks such as object recognition, video games, and board games, achieving performance that equals or even beats humans in some respects. Despite their biological inspiration and performance achievements, these systems differ from human intelligence in crucial ways. We review progress in cognitive science suggesting that truly human-like learning and thinking machines will have to reach beyond current engineering trends in both what they learn, and how they learn it. Specifically, we argue that these machines should (a) build causal models of the world that support explanation and understanding, rather than merely solving pattern recognition problems; (b) ground learning in intuitive theories of physics and psychology, to support and enrich the knowledge that is learned; and (c) harness compositionality and learning-to-learn to rapidly acquire and generalize knowledge to new tasks and situations. We suggest concrete challenges and promising routes towards these goals that can combine the strengths of recent neural network advances with more structured cognitive models.

尽管在现代的机器学习算法的最新进展，其内在机制的不透明仍是采用的障碍。在人工智能系统灌输信心和信任，解释的人工智能已成为提高现代机器学习算法explainability的响应。归纳逻辑程序（ILP），符号人工智能的子场中，起着产生，因为它的直观的逻辑驱动框架的可解释的解释有希望的作用。 ILP有效利用绎推理产生从实例和背景知识解释的一阶分句理论。然而，在发展中通过ILP需要启发方法的几个挑战，在实践中他们的成功应用来解决。例如，现有的ILP系统通常拥有广阔的解空间，以及感应解决方案是对噪声和干扰非常敏感。本次调查总结在ILP的最新进展和统计关系学习和神经象征算法的讨论，其中提供给ILP协同意见。继最新进展的严格审查，我们划定观察的挑战，突出对发展不言自明的人工智能系统进一步ILP动机研究的潜在途径。

Artificial Intelligence (AI) and its applications have sparked extraordinary interest in recent years. This achievement can be ascribed in part to advances in AI subfields including Machine Learning (ML), Computer Vision (CV), and Natural Language Processing (NLP). Deep learning, a sub-field of machine learning that employs artificial neural network concepts, has enabled the most rapid growth in these domains. The integration of vision and language has sparked a lot of attention as a result of this. The tasks have been created in such a way that they properly exemplify the concepts of deep learning. In this review paper, we provide a thorough and an extensive review of the state of the arts approaches, key models design principles and discuss existing datasets, methods, their problem formulation and evaluation measures for VQA and Visual reasoning tasks to understand vision and language representation learning. We also present some potential future paths in this field of research, with the hope that our study may generate new ideas and novel approaches to handle existing difficulties and develop new applications.

虽然深增强学习已成为连续决策问题的有希望的机器学习方法，但对于自动驾驶或医疗应用等高利害域来说仍然不够成熟。在这种情况下，学习的政策需要例如可解释，因此可以在任何部署之前检查它（例如，出于安全性和验证原因）。本调查概述了各种方法，以实现加固学习（RL）的更高可解释性。为此，我们将解释性（作为模型的财产区分开来和解释性（作为HOC操作后的讲话，通过代理的干预），并在RL的背景下讨论它们，并强调前概念。特别是，我们认为可译文的RL可能会拥抱不同的刻面：可解释的投入，可解释（转型/奖励）模型和可解释的决策。根据该计划，我们总结和分析了与可解释的RL相关的最近工作，重点是过去10年来发表的论文。我们还简要讨论了一些相关的研究领域并指向一些潜在的有前途的研究方向。
