Mainstream Domain Knowledge
In the Pathfinder case, we focus on cross-domain applications of Pathfinder
networks, especially those non-mainstream applications of Pathfinder networks that
might be overshadowed by mainstream citation peaks.
The global context of the Pathfinder case shown in Fig. 7.9 contains clusters of
articles on knowledge discovery, knowledge acquisition, classification and machine
learning, artificial intelligence, expert systems, and domain knowledge modeling.
Pathfinder related articles are located in the far side of the landscape view, near to
the area labels of cognitive psychology and expert systems (See Fig. 7.10 ). This
indicates that applications of Pathfinder networks are closely to these two broad
categories. In order to pursue latent knowledge structures associated with Pathfinder
networks. Schvaneveldt's 1985 article was chosen as the first “exit” landmark
because it is located at a point connecting the Pathfinder “peninsula” to other areas
in the landscape.
Tab le 7.3 lists further details concerning the structure of the global context as
derived from factor analysis. Up to 20 leading articles in each of the three largest
