附录
额外信息及资料
本附录简单介绍一些有帮助的信息:其他算法、把数据导入
Neo4j
的另一种方法和另一个
程序库,并提供一些关于查找数据集、平台帮助信息和培训等方面的资源。
其他算法
许多算法可用于图数据。本书重点介绍了经典图算法中最具代表性的算法,以及应用程序
开发人员常用的算法。本书省略了像着色算法和启发式算法这样的算法,这是因为它们要
么在学术案例中更受关注,要么易于推导。
如基于边的社团发现算法等其他算法也都很有意思,但是还未在
Neo4j
或
Spark
中实现。
希望随着图分析应用的发展,这两种平台支持的图算法会不断增加。
还有一些算法虽然可用于图,但本质上并不是严格意义上的图算法,例如第
8
章介绍的一
些在机器学习任务中使用的算法。另一个值得关注的领域是相似度算法,它常用于推荐和
链接预测。相似度算法使用多种方法对节点属性等进行比较,可以计算出哪些节点彼此最
为相似。
