Back in the 80's, there were two AI camps: Syntax and Semantics. My favorite for syntax was Terry Winograd. For semantics was Roger Schank. Back then, I was trying to map AI onto biology. Syntax was easier; you could easily map the edges to a McCullough and Pitts neural model. Semantic nets was harder; the edges were more of a way of modeling symbolic relationships. So, I couldn't wrap my head around Shank. Wish I had; it felt like I was missing the point.
