Yes, it is already available. You just have to close your eyes and try very very hard... Make sure you are all positive in your heart, else it fails (we are working to remove that limitation soon)
Thanks for the interest Tad. The docs/samples/demos collateral should be a good starting point. If you would like to have a deeper engagement, please consider joining the Watson ecosystem program: http://www.ibm.com/smarterplanet/us/en/ibmwatson/ecosystem.h...
See my response to philbarr above about a retail partner. Here is another example related to recruitment. Often we have a need to hire that we identify with another model employee (e.g. wouldnt it be great, if I had a dev like John from TeamX). With the User Modeling service, we had a Hackathon team create a beautiful app where you can ask questions like these and comparing the characteristics of candidates to John, it can find similar matches (of course done in the context of matching skills)
To give an example ... Here is what a retail partner is building with these services around specialized marketing: They have (or get) a user's twitter handle, feed the content authored by the user into the user modeling service and based on the characteristics, send appropriate coupons/offers (e.g. very adventurous or less so etc). Combining that with the machine translation & language identification services, they are able to broaden this to many more languages vs. just English.
The part that they are doing next is: with the community of their users, they want to check the potential resonance of their marketing messages to those users, which they do with the Message Resonance service. Based on that, they can pick the most likely to be resonant message before sending it to the user.
