Numerous studies have been conducted to identify the effects of natural crises on supply chain performance. Conventional analysis methods are based on either manual filter methods or data-driven methods. The manual filter methods suffer from validation problems due to sampling limitations, and data-driven methods suffer from the nature of crisis data which are vague and complex. This study aims to present an intelligent analysis model to automatically identify the effects of natural crises such as the COVID-19 pandemic on the supply chain through metadata generated on social media. This paper presents a thematic analysis framework to extract knowledge under user steering. This framework uses a text-mining approach, including co-occurrence term analysis and knowledge map construction. As a case study to approve our proposed model, we retrieved, cleaned, and analyzed 1024 online textual reports on supply chain crises published during the COVID-19 pandemic in 2019-2021. We conducted a thematic analysis of the collected data and achieved a knowledge map on the impact of the COVID-19 crisis on the supply chain. The resultant knowledge map consists of five main areas (and related sub-areas), including (1) food retail, (2) food services, (3) manufacturing, (4) consumers, and (5) logistics. We checked and validated the analytical results with some field experts. This experiment achieved 53 crisis knowledge propositions classified from 25,272 sentences with 631,799 terms and 31,864 unique terms using just three user-system interaction steps, which shows the model's high performance. The results lead us to conclude that the proposed model could be used effectively and efficiently as a decision support system, especially for crises in the supply chain analysis.
已经有许多研究致力于确定自然危机对供应链绩效的影响。传统的分析方法基于手动筛选方法或数据驱动方法。手动筛选方法由于采样限制存在验证问题,而数据驱动方法则受到危机数据的性质的影响,这些数据模糊且复杂。本研究旨在通过社交媒体上生成的元数据,提出一种智能分析模型,自动识别自然危机(如 COVID-19 大流行)对供应链的影响。本文提出了一个主题分析框架,通过用户引导提取知识。该框架使用文本挖掘方法,包括共现词分析和知识图谱构建。作为批准我们提出的模型的案例研究,我们检索、清理和分析了 2019-2021 年期间在 COVID-19 大流行期间发布的 1024 篇关于供应链危机的在线文本报告。我们对收集到的数据进行了主题分析,并构建了一个关于 COVID-19 危机对供应链影响的知识图谱。生成的知识图谱包含五个主要领域(和相关子领域),包括(1)食品零售,(2)食品服务,(3)制造业,(4)消费者,以及(5)物流。我们与一些现场专家一起检查和验证了分析结果。该实验仅通过三个用户-系统交互步骤,从 25272 个句子、631799 个词和 31864 个唯一词中分类得到 53 个危机知识命题,这表明该模型的性能很高。结果表明,所提出的模型可以有效地用作决策支持系统,特别是在供应链分析中的危机。
