Expert System S.p.A. update

I chatted with Brooke Aker, the new CEO of Expert System’s US subsidiary, for quite a while last week. Unfortunately, we had some cell phone problems, and email followup hasn’t gone well, so I’m hazy on a few details. But here are some highlights, as best I understood them.

Once again, however, I made it through an Expert System briefing without gaining a real understanding of its technology. I gather they’re proud of their in-memory data structure for their semantic network, but I haven’t a clue (beyond the obvious guesses) as to what that data structure is. Similarly, Brooke said that a distinguishing feature of Expert Systems semantic network is that words have lots of attributes, which are the same thing as categories, and supplied a list of the 11 top-level categories: Objects, animals, plants, people, concepts, places, time, natural phenomena, state, quantity, group. But it’s easy to come up with a lot of things that don’t seem to fit that list very well (especially events, such as numerous different word-senses of “strike”), so absent further elucidation I didn’t find that particularly instructive either.

    Just wanted to make a correction to the Expert System assertion that they beat out Lexalytics on this deal. In point of fact, I don’t know which auto companies they are talking about, and can say with 100% confidence that we weren’t one of the companies they (whoever they are) were looking at. No phone calls, and no emails says to me that we weren’t considered on these.
