摘要:本文从零开始引导与大家一起学习图知识.希望大家可以通过本教程学习如何使用图数据库与图计算引擎.本篇将以华为云图引擎服务来辅助大家学习如何使用图数据库与图计算引擎. 本文分享自华为云社区<从零开始学Graph Database(1)>,作者:弓乙 . 基础概念 什么是图? 首先,我们需要明确图 Graph的概念. 这里的图,是graph, 是graphical,而不是graphic.即图处理的是关系问题,而不是图片.我们解决是关系问题,而非视觉cv问题. 在离散数据中,有专门研究图的图论.…

Motivation 图数据库中的高科技和高安全性中引用了一个关于图数据库(graph database)的应用前景的乐观估计: 预计到2017年,图数据库产业在数据库市场的份额将从2个百分点增长到25个百分点,在此过程中图数据库工具将会逐步获得企业认可,并且其消费群体会持续增长. 文中从图发现.图知识管理和图预测角度阐述图数据库生态系统面临的技术和安全性挑战. 由于有语义网初步研究的背景,对图数据库NoSQL实现中triple概念感到亲切:在一本名为Graph database的Neo4j技术…

图数据库(英语:Graph Database)是一个使用图结构进行语义查询的数据库.该系统的关键概念是图,形式上是点 (Node 或者 Vertex) 和边 (Edge 或者 Relationship) 的集合.一个顶点代表一个实体,比如,某个人,边则表示两个实体间的关联关系,比如 "你关注 Nebula Graph"的关注关系.图广泛存在于现实世界中,从社交网络到风控场景.从知识图谱到智能推荐. Nebula Graph 是什么 Nebula Graph 是一款开源的分布式图数据库,…

1.图是什么? 本文给出得图的定义为:A graph represents the relations (edges) between a collection of entities (nodes). 即:图表示实体(节点)集合之间的关系(边). 其中 $V$  表示顶点,$E$  表示边,$U$  表示全局.可以看到每一个定义后面都有一个 attributes,这意味着我们不能只关注图的一个结构信息,还应该关注属性信息,比如节点的邻居数,边的权重,最长路径等等. $V$:节点信息(节点标识.…
