That's a good summary of the issues.  From page 32:

There is a way to find such relationships:

  1. Translate every document in a corpus to a semantic network in
     any of the many notations that have been used over the years.

  2. Store all the graphs in a system that enables any query graph
     to retrieve all similar graphs within a given semantic distance.

To be practical, this method requires a system that allows similar
graphs to be retrieved in time proportional to the logarithm of the
number of graphs in the store. For issues and citations, see slides
129 to 132 of http://www.jfsowa.com/talks/goal.pdf

The remaining slides show some applications that use such a store.
