The so-called "IA" ("Intelligent Assistant") subsystem used these frames so that it could guess things like the fact that when you write "Joe" you probably mean "Joseph Smith" or "Josephine Baker" from your address book. Recently, I started reading the chapters on Logic Programming in SICP and tried to learn more about Prolog and Frames. It surprised me to see something so "theoretical" used in a consumer-facing product, even though it ultimately failed. Alan, do you know more about these systems, and how they were put together? Z-Bo, sorry if I'm hijacking your thread. -- Duncan.
