Table 2 Survived graph features in sequential VIF comparisons in picture description task.

From: Who does what to whom? graph representations of action-predication in speech relate to psychopathological dimensions of psychosis

  1. Columns within each segment accommodate survived graph features. VIF comparison was conducted and features of the highest VIF were excluded successively until a set of features all showing VIF < 5 was attained. Survived features were then passed to the next column on right for another comparison on a more integrated level. 1. Domain column shows results of intra-domain comparisons. 2. Type column presents the features integrated on graph-type level, i.e., semantic vs structural graph features. 3. Task column combines all graph features per each task. For the dynamic semantic graph, features belonging to three domains of size, connectedness and organization remained in the final set. Graph features of different methods are color coded. VIF comparisons for open-ended narrative task is provided in Supplementary Table 4. More details on graph features are available in Supplementary Table 3.
  2. S_AP static action-predication graph feature, D_AP dynamic action-predication graph feature, S_SEQ static sequential graph feature, D_SEQ dynamic sequential graph feature, NN number of nodes, NE number of edges, diameter graph diameter, ASPL average shortest path length, AWD average weighted degree, density graph density, LSCC size of largest strongly connected component, LSCCZ z-score of LSCC compared to 1000 random graphs, ASPLZ z-score of ASPL compared to 1000 random graphs.
