Network analysis: A short introduction to the core concepts of centrality, paths, and topology

A short introduction to the core concepts of network analysis. The presentation provides a minimal introduction to node centrality metrics, path analysis, and global network structure including scale-free networks. It also gives some words of caution regarding the interpretation of results from network analysis. You may want to watch my short introduction to the core concepts of network biology first: • Network biology: A sho...
0:00 Introduction: characterization of individual nodes and overall network structure
0:30 Centrality: node importance, degree centrality, in-degree, out-degree, and betweenness centrality
1:40 Path analysis: path between two nodes, shortest path, directed network, and weighted network
2:28 Global characterization: network diameter, characteristic path length, degree distribution, power law, and scale-free topology
3:57 Words of caution: study bias, its impact on degree centrality / scale-free topology, lack of flow in undirected networks, and interpretation of paths / betweenness centrality
