Finding analogies is essentially a problem of searching for
patterns in some kind of representation.  In VAE, everything
is represented as graphs.  An analogy to one graph is another
graph that has a small semantic distance from the first.    (03)

An older technology, which uses frames rather than graphs, was
implemented by Falkenhainer, Forbus, and Gentner.  Frames are
just a special case of graphs, so anything that is represented
in a collection of frames can be translated to a collection
of graphs.    (04)

The citation at the end of the slides points to the following
article:    (05)

    http://www.jfsowa.com/pubs/analog.htm    (06)

This article goes into more detail, and it cites the earlier work,
much of which is available on the web.  (Check Google.)  You can
download their software and run it on your computer.  VAE is faster,
but the older software may be easier to understand.    (07)
