metapath2vec | Proceedings of the 23rd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining

Abstract

• word2vec → node2vec (homogeneous) → metapath2vec (heterogeneous)
• Metapath-based word2vec method
  • In a nutshell, Applied "Node2Vec" for Heterogeneous Graph

Background: Heterogeneous Graph

• Mining Heterogeneous Information Networks: A Structural Analysis Approach (KDD'12)

Heterogeneous Graph?

The graph where the number of types of nodes and their relations are more than 1

Schema & Network

Metapath

• By different meta-path comes different output

Strength for link types (weighted Meta-path)

• Can use different weights following types of links to make proper graph mining
