Predicting market movements based on the sentiment of news media has a long tradition in data analysis. With advances in natural language processing, transformer architectures have emerged that enable contextually aware sentiment classification. Nevertheless, current methods built for the general financial market such as FinBERT cannot distinguish asset-specific value-driving factors. This paper addresses this shortcoming by presenting a method that identifies and classifies events that impact supply and demand in the crude oil markets within a large corpus of relevant news headlines. We then introduce CrudeBERT, a new sentiment analysis model that draws upon these events to contextualize and fine-tune FinBERT, thereby yielding improved sentiment classifications for headlines related to the crude oil futures market. An extensive evaluation demonstrates that CrudeBERT outperforms proprietary and open-source solutions in the domain of crude oil.
基于新闻媒体情绪预测市场走势在数据分析中有着悠久的传统。随着自然语言处理的进步,转换器架构已经出现,可以实现上下文感知的情感分类。然而,目前为一般金融市场(如FinBERT)建立的方法无法区分特定资产的价值驱动因素。本文通过提出一种在大量相关新闻标题中识别和分类影响原油市场供需的事件的方法来解决这一缺点。然后,我们引入了一个新的情绪分析模型CrudeBERT,该模型利用这些事件来背景化和微调FinBERT,从而对与原油期货市场相关的头条新闻产生改进的情绪分类。一项广泛的评估表明,在原油领域,CrudeBERT优于专有和开源解决方案。

Recent events such as wars, sanctions, pandemics, and climate change have shown the importance of proper supply network management. A key step in managing supply networks is procurement. We present an approach for realizing a next-generation procurement workspace that aims to facilitate resilience and sustainability. To achieve this, the approach encompasses a novel way of information integration, automation tools as well as analytical techniques. As a result, the procurement can be viewed from the perspective of the environmental impact, comprising and aggregating sustainability scores along the supply chain. We suggest and present an implementation of our approach, which is meanwhile used in a global Fortune 500 company. We further present the results of an empirical evaluation study, where we performed in-depth interviews with the stakeholders of the novel procurement platform to validate its adequacy, usability, and innovativeness.
最近发生的战争、制裁、流行病和气候变化等事件显示了适当的供应网络管理的重要性。管理供应网络的一个关键步骤是采购。我们提出了一种实现下一代采购工作空间的方法,旨在促进弹性和可持续性。为了实现这一目标,该方法包括一种新的信息集成方式、自动化工具以及分析技术。因此,可以从环境影响的角度来看待采购,包括并汇总供应链上的可持续性得分。我们建议并介绍了我们的方法的实施,该方法同时在一家全球财富500强公司中使用。我们进一步提出了一项实证评估研究的结果,我们对新型采购平台的利益相关者进行了深入访谈,以验证其充分性、可用性和创新性。

The process of identifying and managing Information and Communication Technology (ICT) risks has become a concern and a challenge for public and private organizations. In this context, risk management methodologies within the Brazilian Federal Public Administration organizations have become indispensable to help the managers of these organizations in decision making, especially in the distribution of public funds, elaboration of public policies focused on transparency, social actions contemplating indemnities, and social benefits, among others. In addition, the various ICT projects controlled by the public administration need a methodology to perform their management of ICT resources. In this article, we present the Governance and Risk Management methodology used to model the Administrative Council for Economic Defense (CADE) macro processes. The proposed methodology used the risk management process aligned to the ISO 31000 standards. This alignment was necessary for mapping CADE’s risk events, regardless of their complexity. The modeled ICT risk processes will support the organization’s managers in decision making and may be used or customized by any other organization of the Brazilian Federal Public Administration.
识别和管理信息和通信技术(ICT)风险的过程已成为公共和私人组织的关注和挑战。在这方面,巴西联邦公共行政组织内部的风险管理方法已成为帮助这些组织的管理人员进行决策,特别是在分配公共资金、拟订以透明度为重点的公共政策、考虑赔偿和社会福利的社会行动等方面不可或缺的方法。此外,公共行政部门控制的各种信息和通信技术项目需要一种方法来管理信息和通信技术资源。在本文中,我们介绍了用于模拟经济防御行政委员会(CADE)宏观过程的治理和风险管理方法。建议的方法使用与ISO 31000标准一致的风险管理过程。这种对齐对于映射CADE的风险事件是必要的,而不管它们的复杂性如何。建模的ICT风险流程将支持该组织的管理人员进行决策,并可由巴西联邦公共行政的任何其他组织使用或定制。

Towards Unlocking the Potential of the Internet of Things for the Skilled Crafts 为技工解锁物联网的潜力

: The Internet of Things (IoT) enables companies to develop new digital business models or optimize existing processes through digitalization. Since value creation in the skilled crafts is determined by the manufacturing of material products and the provision of associated services, it is predestined for the use of IoT technologies. While these services are increasingly finding their way into the consumer market via industrial providers, the local skilled crafts with its small and medium-sized businesses lacks the knowledge to assess the potential and to adequately develop and operate IoT solutions. Our aim is to develop a manufacturer-independent platform that enables those businesses to implement IoT solutions independently. The platform is intended to support craftsmen in identifying suitable IoT use cases and resulting business models for their trades, products or services. For that, it will provide an overview of the components (e.g., sensors) required for the respective use cases. Based on this, the use cases can be set up without special know-how with the help of the platform, which also collects and manages the accruing data. Each craft business can identify new use cases and make them available to the other users of the platform, thus creating a cross-trade solution from the skilled crafts for the skilled crafts. Potential IoT use cases and their technical requirements were already identified in a pre-study in collaborative hackathons and will be evaluated during the development of the IoT Crafts Portal. The results are intended to assist craft businesses from a wide range of trades to identify and implement new business models in such a way that they can be integrated into the existing processes of the businesses. At the same time, there will be a transfer of knowledge between the craft businesses themselves, since each can use the experience of the other business or offer its own insights.
物联网(IoT)使公司能够通过数字化开发新的数字商业模式或优化现有流程。由于技术工艺的价值创造是由材料产品的制造和相关服务的提供决定的,因此注定要使用物联网技术。虽然这些服务越来越多地通过工业供应商进入消费者市场,但当地的中小型企业缺乏评估潜力和充分开发和运营物联网解决方案的知识。我们的目标是开发一个独立于制造商的平台,使这些企业能够独立实施物联网解决方案。该平台旨在支持工匠识别合适的物联网用例,并为他们的行业、产品或服务提供相应的商业模式。为此,它将提供各个用例所需的组件(例如,传感器)的概述。在此基础上,可以在平台的帮助下建立用例,而不需要专门的知识,平台还可以收集和管理积累的数据。每个工艺业务都可以识别新的用例,并将其提供给平台的其他用户,从而创建一个从熟练工艺到熟练工艺的跨行业解决方案。潜在的物联网用例及其技术要求已经在协作黑客马拉松的预研究中确定,并将在物联网工艺门户的开发过程中进行评估。研究结果旨在帮助各行各业的工艺企业识别和实施新的业务模式,以便将其集成到现有的业务流程中。同时,工艺企业之间也会有知识的转移,因为每个企业都可以利用其他企业的经验或提供自己的见解。

As industries are becoming increasingly digitalized, new manufacturing concepts require redesigning the information systems architecture. The Smart Production Laboratory is used as a learning factory aimed at exploring new industry 4.0 technologies and for demonstrating Smart Production solutions. The initial Smart Production Laboratory was built on a proprietary software stack. Experimenting with the information systems architecture using proprietary systems has shown to be difficult, which is why we built a complete modular open-source software stack for the Smart Production Laboratory intended to enable high-speed and low-cost development of demonstrators for research, teaching, and innovation. Therefore, the purpose of this research is to capture the development of the software stack and identify the required target architecture for the platform. This is further used for discussing potential future challenges in demonstrating new and innovative Smart Production concepts.
随着工业日益数字化,新的制造概念要求重新设计信息系统架构。智能生产实验室是一个学习型工厂,旨在探索新的工业4.0技术,并展示智能生产解决方案。最初的智能生产实验室是建立在一个专有软件堆栈上的。使用专有系统对信息系统体系结构进行实验已经证明是困难的,这就是为什么我们为智能生产实验室构建了一个完整的模块化开源软件堆栈,旨在实现用于研究、教学和创新的演示的高速和低成本开发。因此,本研究的目的是捕捉软件堆栈的开发,并确定平台所需的目标体系结构。这进一步用于讨论在展示新的和创新的智能生产概念时潜在的未来挑战。

When aggregating logistic event data from different supply chain actors and information systems for process mining, interoperability, data loss, and data quality are common challenges. This position paper proposes and evaluates the use of the Open Trip Model (OTM) for process mining. Inspired by the current industrial use of the OTM for reporting and business intelligence, we believe that the data model of OTM can be utilized for unified storage, integration, interoperability, and querying of logistic event data. Therefore, the OTM data model is mapped to a generic event log structure to satisfy the minimum requirements for process mining. A demonstrative scenario is used to show how event data can be extracted from the OTM’s default scenario dataset to create an event log as the starting point for process mining. Thus, this approach provides a foundation for future research about interoperability challenges and unifying process mining models based on industry standards, and a starting point for developing process mining applications in the logistics industry.
在聚合来自不同供应链参与者和信息系统的物流事件数据以进行流程挖掘时,互操作性、数据丢失和数据质量是常见的挑战。本立场文件提出并评估了开放式行程模型(OTM)在过程挖掘中的使用。受到OTM用于报告和商业智能的当前工业用途的启发,我们相信OTM的数据模型可以用于统一存储、集成、互操作性和查询物流事件数据。因此,将OTM数据模型映射到通用的事件日志结构,以满足流程挖掘的最低要求。演示场景用于展示如何从OTM的默认场景数据集中提取事件数据,以创建事件日志作为流程挖掘的起点。因此,该方法为未来研究互操作性挑战和基于行业标准的统一流程挖掘模型提供了基础,并为开发物流行业的流程挖掘应用提供了起点。

Object Detection (OD) is an important computer vision problem for industry, which can be used for quality control in the production lines, among other applications. Recently, Deep Learning (DL) methods have enabled practitioners to train OD models performing well on complex real world images. However, the adoption of these models in industry is still limited by the difficulty and the significant cost of collecting high quality training datasets. On the other hand, when applying OD to the context of production lines, CAD models of the objects to be detected are often available. In this paper, we introduce a fully automated method that uses a CAD model of an object and returns a fully trained OD model for detecting this object. To do this, we created a Blender script that generates realistic labeled datasets of images containing the object, which are then used for training the OD model. The method is validated experimentally on two practical examples, showing that this approach can generate OD models performing well on real images, while being trained only on synthetic images. The proposed method has potential to facilitate the adoption of object detection models in industry as it is easy to adapt for new objects and highly flexible. Hence, it can result in significant costs reduction, gains in productivity and improved products quality.
物体检测(OD)是一个重要的工业计算机视觉问题,它可以用于生产线的质量控制,以及其他应用。最近,深度学习(DL)方法使从业者能够训练在复杂的真实世界图像上表现良好的OD模型。然而,在工业中采用这些模型仍然受到收集高质量训练数据集的难度和巨大成本的限制。另一方面,当将OD应用于生产线时,通常可以使用要检测对象的CAD模型。在本文中,我们介绍了一种全自动方法,该方法使用对象的CAD模型并返回经过完全训练的OD模型来检测该对象。为此,我们创建了一个Blender脚本,生成包含对象的图像的真实标记数据集,然后用于训练OD模型。通过两个实例的实验验证了该方法的有效性,表明该方法可以生成在真实图像上表现良好的OD模型,而只能在合成图像上进行训练。由于该方法易于适应新对象且高度灵活,因此具有促进工业中对象检测模型采用的潜力。因此,它可以显著降低成本,提高生产率和提高产品质量。

A Data-centered Usage Governance: Providing Life-long Protection to Data Exchanged in Virtual Enterprises 以数据为中心的使用治理:为虚拟企业中交换的数据提供终身保护

: Since the early definition of the Virtual Enterprise concept in the 90s, efficient information sharing and trust have been pointed out as major challenges to support the enactment of collaborative organisations. By now, traditional Collaborative Business support systems have been designed to interconnect corporate Business Processes and different well-known information systems, whereas trust is mostly managed thanks to inter-personal relationships. Unfortunately, this well-perimetrized vision of a Collaborative Network Organization does not fit the large scale, opened and evolving context due to the fast adoption of Industry 4.0 and sharing economy models which rely on the large scale adoption of Social Mobile Analytics Cloud Internet of Things technologies (later called SMACIT for short) and semi-opened information systems. This involves rethinking the way information, services and applications are organized, deployed, shared and protected, moving from the traditional perimetrized system protection to data and service life-long usage control. To this end, we propose a data-driven security organization which uses a multi-layer architecture to describe on one hand the logical organisation of the information system, i.e. the data assets and the business services needed to implement the collaborative business processes and on the other hand the multiple copies exchanged with different service providers. Based on this Information System meta-model, our system integrates a blockchain-based usage manager to govern the way information are exchanged and processed.
自90年代虚拟企业概念的早期定义以来,有效的信息共享和信任已被指出是支持建立协作组织的主要挑战。到目前为止,传统的协同业务支持系统已经被设计用于连接企业业务流程和不同的知名信息系统,而信任主要是通过人际关系来管理的。不幸的是,由于工业4.0和共享经济模式的快速采用,协作网络组织的这种良好的边缘化愿景并不适合大规模,开放和不断发展的背景,这些模式依赖于大规模采用社交移动分析云物联网技术(后来简称为SMACIT)和半开放的信息系统。这需要重新思考信息、服务和应用程序的组织、部署、共享和保护方式,从传统的边缘系统保护转向数据和服务终身使用控制。为此,我们提出了一种数据驱动的安全组织,该组织使用多层体系结构来描述信息系统的逻辑组织,即实现协作业务流程所需的数据资产和业务服务,以及与不同服务提供者交换的多个副本。基于这个信息系统元模型,我们的系统集成了一个基于区块链的使用管理器来管理信息的交换和处理方式。

By now, traditional Collaborative Business support systems have been designed to interconnect corporate Business Processes and different well-known information systems, whereas trust is mostly managed thanks to inter-personal relationships. Unfortunately, this well-perimetrized vision of a Collaborative Network Organization does not fit the large scale, opened and evolving context due to the fast adoption of Industry 4.0 and sharing economy models which rely on the large scale adoption of Social Mobile Analytics Cloud Internet of Things technologies (later called SMACIT for short) and semi-opened information systems.

: Organizations around the world today face many challenges, and not all of them are unique. Such repeatable problems can themselves be solved by reusable solutions. This study focuses on Enterprise Architecture Patterns, reusable solutions to repeating challenges organizations face. Through a systematic literature review, we aim to gather an exhaustive recollection of all such patterns in literature. In order to be as comprehensive as possible, the sample included related fields also researching patterns. The result is a collection of 593 patterns and their respective analysis, which will help practitioners tackle their challenges.
当今世界各地的组织面临着许多挑战,并不是所有的挑战都是独一无二的。这些可重复出现的问题本身可以通过可重用的解决方案来解决。本研究的重点是企业架构模式,即组织面临的重复挑战的可重用解决方案。通过系统的文献回顾,我们的目标是在文献中收集所有这些模式的详尽回忆。为了尽可能全面,样本中包含了相关领域和研究模式。结果是593种模式的集合以及它们各自的分析,这将帮助从业者解决他们的挑战。
