I think Stack Overflow could be a very interesting AI test bed for answer bots.
Obviously it would be too much work for a single person, but maybe a university or corporate research group...
I'm thinking specifically about the IBM DeepQA bot.
It seems like it might be able to at least ID and answer the most easy "what is the definition of:"-style questions on Stack Overflow, which is why I was wondering whether it had been done before.
Do you think such a bot would be capable of maintaining a positive reputation on Stack Overflow? Or would wrong answers pummel it into the group?
