	There is definitely some work going on in this area.
My Ph.D research topic is concerned with developing a method 
which will extract rules from a neural network.  Some of our
published papers are:

	"Machine learning using single-layered and multi-layered
	neural networks" by Sabrina Sestito and Tharam Dillon,
	in Tools for AI, Wahington D.C., 1990

	"Using multi-layered neural networks for learning 
	symbolic knowledge" by Sabrina Sestito and Tharam Dillon,
	in AI'90, Perth, Australia, 1990.

The extension of this work, to determine disjunctive rules 
has also been developed, but at this stage has not been 
published.  

	Any comments would be appreciated.
