Some references to other episodes Weird Studies/A Glitch in the Matrix and Memory Palaces and I realized that MUE was me trying to construct a House for myself, or at least, my image of the user was like Piranesi, inhabiting this abstract space of concepts and navigating around in it. (Although I didn't intent to trap my users there forever).
I worked with the Cyc team for a couple of summers as a graduate student, but it was at a time when I was absorbing a lot of the situated action critique of AI, and the approach of Cyc was quite antithetical. But it was still a neat project! I got past my intellectual qualms by focusing on the user interface, a oft-used strategy of mine, and got a paper out of it A Visual Representation for Knowledge Structures (See MUE)
