Fig. 6

The Impact of Knowledge Model Harmonization on the Semantically Abstracted PKT Human Disease Knowledge Graphs. The figure visualizes the impact of knowledge model harmonization on the semantically abstracted PKT Human Disease benchmark Knowledge Graphs. The top row of figures (a–d) were built using the class-based knowledge model varying: (a) standard relations without harmonization; (b) standard relations with harmonization; (c) inverse relations without harmonization; (d) inverse relations with harmonization. The bottom row of figures (e-h) were built using the instance-based knowledge model varying: (e) standard relations without harmonization; (f) standard relations with harmonization; (g) inverse relations without harmonization; (h) inverse relations with harmonization. Nodes are colored by type: anatomical entities (light blue), chemical entities (light purple), diseases (red), genes (purple), genomic features (light green), organisms (yellow), pathways (dark green), phenotypes (magenta), proteins (dark blue), molecular sequences (orange), transcripts (turquoise), and variants (light pink).
