Patterns of co-occurrent skills in UK job adverts
Fig 2
Optimal skill clusters at different resolutions as obtained by Markov Stability (MS) on the sparsified skills graph .
MS identifies five robust graph partitions of increasing coarseness, from 189 clusters to 4 clusters, as indicated by minima of the Block NVI (points on the purple line) [36–39]. The partitions of the skills network into 21, 7 and 4 skill clusters (with nodes coloured according to their cluster) are shown at the top. The corresponding skill clusters, and their quasi-hierarchical structure, are summarised in the Sankey diagram in Fig 3. For further details on MS, see S1A Appendix.
