Note, in Figures 5 and 6, some nodes are essentially the same, as shown in Table 1.
Table 1. Node equivalences between 2 K-lines
Node of KL1
Node of KL2
Each row of Table 1 shows two nodes, one from K-line KL1 and one from K-line
KL2. Each row of Table 1 contains nodes that are the same, or essentially equivalent,
according to the K-lines of Figures 5 and 6. Based on this observation, the two separate
K-lines are said to intersect , and they can be merged into a graph, as shown in Figure 7.
Fig. 7. Intersecting K-lines
Note, in Figure 7, the edge connecting nodes 15 and 16 belongs to both K-lines.
We argue that the knowledge conveyed by Figure 7 is superior to the knowledge con-
veyed individually by Figures 5 and 6. Next, we explain why this is the case.
