A lot depends on what you mean by semantic networks. The Pop-11
matcher and database are used for lots of teaching which can be
construed as involving semantic nets and propagation of information.

For example see
    TEACH INFECT
    TEACH DATATHINK

More interestingly see
    TEACH SCHEMATA

These would be very inefficient for serious work, but if your
networks are small (or can easily be partitioned into lots of small
networks) then that sort of technique can work.

If anyone is using NEWPSYS please note that it is now obsolete:
there's a new version called POPRULEBASE available in the Birmingham
Poplog ftp directory
