[comp.ai.digest] references re

RJZ@JASPER.PALLADIAN.COM (Roland Zito-Wolf) (05/28/87)

I am looking for references regarding the matching of complex structures
(matching on semantic networks or portions of networks) such as arise in doing
retrieval operations on knowledge-bases so represented.		
Since the general mathcing problem is most likely intractable, I'm 
looking for approximate or incomplete techniques, such as partial match,
resource-bounded match, matches using preference rules, etc.
References which explore algorithms in detail, and implemented systems,
would be especially useful. For example, does anyone know of a
detailed description of the KRL matcher?

Information on the more general problem of query/data-retrieval from 
semantic networks would also be useful.

If there's sufficient interest, I'll post the results to the digest.
Thanks in advance.
