Earlier this year, I conducted an archeological dig on Watson. I applied the techniques I've developed for the Handbook which involves the use of the UML, Philippe Kruchten's 4+1 View Model, and IBM's Rational Software Architect. The fruits of this work have proven to be useful as groups other than Watson's original developers begin to transform the Watson code base for use in other domains.
You can watch my presentation at IBM Innovate on How Watson Works here.
