Fig. 7.9 An overview of the mainstream domain knowledge

factors, or specialties, are listed. In essence, factor one corresponds to research in
Pathfinder networks. Factor two corresponds to classic artificial intelligence. Factor
three corresponds to expert systems and decision support systems. The higher a

specialty. On the other hand, if an article has a wide impact, then its loadings on
individual factors may not be exceedingly high.

Figure 7.11 shows the latent knowledge structure derived from the citing space of
the “exit” landmark article. This structure is not overshadowed by high citations
