图的概念和应用

In an introductory article, we talked about the importance of Graph Networks in fraud detection. In this article, we will be adding some further context on graphs, graph technology and some common use cases.

在一篇介绍性文章中，我们谈到了图网络在欺诈检测中的重要性。在这篇文章中，我们将进一步补充一些关于图、图技术和一些常见用例的背景。

Connectivity is the most prominent feature of today’s networks and systems. From molecular interactions, social networks and communication systems to power grids, shopping experiences or even supply chains, networks relating to real-world systems are not random. This means that these connections are not static and can be displayed differently at different times. Simple statistical analysis is insufficient to effectively characterise, let alone forecast, networked system behaviour.

连接性是当今网络和系统最突出的特征。从分子互动、社交网络和通信系统到电网、购物体验甚至供应链，与现实世界系统有关的网络不是随机的。这意味着这些连接不是静态的，在不同的时间会有不同的显示。简单的统计分析不足以有效地描述网络系统的行为特征，更不用说预测了。

As the world becomes more interconnected and systems become more complex, it is more important to employ technologies that are built to take advantage of relationships and their dynamic properties. There is no doubt that graphs have sparked a lot of attention because they are seen as a means to get insights from related data. Graph theory-based approaches show the concepts underlying the behaviour of massively complex systems and networks.

随着世界变得更加相互关联，系统变得更加复杂，采用为利用关系及其动态属性而构建的技术就变得更加重要。毫无疑问，图已经引发了大量的关注，因为它们被视为从相关数据中获得洞察力的一种手段。基于图论的方法显示了大规模复杂系统和网络行为的基本概念。

What are graphs?

什么是图表？

Graphs are mathematical models frequently used in network science, which is a set of technological tools that may be applied to almost any subject. To put it simply, graphs are mathematical representations of complex systems.

图是网络科学中经常使用的数学模型，它是一套可应用于几乎所有学科的技术工具。简单地说，图是复杂系统的数学表示法。

Origin of graphs

图形的起源

The first graph was produced in 1736 in the city of Königsberg, now known as Kaliningrad, Russia. In this city, there were two islands with two mainland sections that were connected by seven different bridges.

第一张图是1736年在柯尼斯堡市产生的，现在被称为俄罗斯的加里宁格勒。在这个城市，有两个岛屿，有两个大陆部分，由七座不同的桥梁连...
