摘要翻译：
范畴化是我们理解世界和进行集体交流的重要组成部分。因此，必须认识到分类制度不一定是一成不变的，特别是对经济系统而言，在大多数创新发生和实施的城市地区更是如此。过时的分类系统可能会限制对当前经济的进一步理解，因为事情总是在变化。在这里，我们为美国劳动经济开发了一个基于职业的分类系统，称为工业主题，它满足适应性和代表性。通过利用职业在美国城市地区的分布，我们确定了产业主题--基于职业共存模式的职业集群。产业专题说明了不同职业系统配置下的机制。将紧密联系的职业视为一个产业主题，我们的方法通过它们的主题构成来描述区域经济。与现有的以调查为基础的自上而下的方法不同，我们的方法提供了关于区域经济基本结构的及时信息，这对政策制定者和商业领袖至关重要，尤其是在我们快速变化的经济中。

分类信息：
一级分类：Computer Science 计算机科学
二级分类：Social and Information Networks 社会和信息网络
分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.
涵盖社会和信息网络的设计、分析和建模，包括它们在联机信息访问、通信和交互方面的应用，以及它们作为数据集在这些领域和其他领域的问题探索中的作用，包括与社会和生物科学的联系。这类网络的分析和建模包括ACM学科类F.2、G.2、G.3、H.2和I.2的主题；计算应用包括H.3、H.4和H.5中的主题；计算和其他学科接口的应用程序包括J.1-J.7中的主题。关于计算机通信系统和网络协议（例如TCP/IP）的论文通常更适合网络和因特网体系结构（CS.NI）类别。

英文摘要：
Categorization is an essential component for us to understand the world for ourselves and to communicate it collectively. It is therefore important to recognize that classification system are not necessarily static, especially for economic systems, and even more so in urban areas where most innovation takes place and is implemented. Out-of-date classification systems would potentially limit further understanding of the current economy because things constantly change. Here, we develop an occupation-based classification system for the US labor economy, called industrial topics, that satisfy adaptability and representability. By leveraging the distributions of occupations across the US urban areas, we identify industrial topics - clusters of occupations based on their co-existence pattern. Industrial topics indicate the mechanisms under the systematic allocation of different occupations. Considering the densely connected occupations as an industrial topic, our approach characterizes regional economies by their topical composition. Unlike the existing survey-based top-down approach, our method provides timely information about the underlying structure of the regional economy, which is critical for policymakers and business leaders, especially in our fast-changing economy.
