Earlier quoted context omitted.

Or, we could learn to do brief history searches and check out past user comments if it really matters. I'm generally pretty suspicious of any sort of computer-generated personality profiles, and though I understand the appeal to techies of empathy-as-a-service I don't think it's something we should consider relying upon. Hell, half the fun in life is trying to figure out who other people really are.

Empathy-as-a-service is the killer app for Google Glass. Finally!

Actually, that's way less far-fetched than you think: http://www.autismspeaks.org/news/news-item/google-glass-app-...

Somewhere, an ad executive is thinking up a commercial about humanizing glassholes...

I wonder if this data might be more interesting on the bottom 100 users with a longevity > 2 years. And of course it would be interesting to see the differences between the top 100 HN users and the top 100 Reddit users. That might provide some insight into the echo chamber effect.

Are there any other services that offer similar functionality to the User Modeling API? I've come across a few Sentiment Analysis services, but nothing with this level of detail.

You can run MBTI albeit as 4 separate API calls.

I had a small giggle at my rankings, not going to lie. Without a definition for what each of these things are, it's a little unclear what this is actually saying. I'm assuming there's some documentation on this somewhere?

IBM's/Watson's documentation is really vague on what these things are, but there's some explaination to that in Wikipedia: http://en.wikipedia.org/wiki/Big_Five_personality_traits One thing that we're wondering is whether a score 1% means that it believes that the person has little of this treat, or that it has little proof to believe that the person has this treat. If I'm not mistaken it's the former.

Yes, former. It may be useful to translate these into other systems[0] so that you see what each end of the spectrum means.

That's really cool. For some reason, the ranking changes every time I click on the same category. Edit: I just realised it's probably because the position of users who have the same score is randomised.

Also, why is Libertatea (https://news.ycombinator.com/threads?id=Libertatea) ranking so high in many categories and yet he only has 5 posts?

I think that IBM Watson expects a general text no? I admit to having done some personality classification on OKC profiles (around 200) and found that disproportionately to the average population, there were a lot of people that were classified as caring, helpful, social, popular individuals.

It fits the medium. Just like one would expect HN comments to be full of more "head-y" discussions.

Libertatea's score was computed on a very low number of comments so it may contain large errors, pergaps we should remove him/her or show a warning there...
