We could write down our problems in simple English. We then use do a natural language parsing (NLP), and transform the output to Prolog code. We execute the Prolog code and use a search engine to find the solution. Each result is used an input for another (second) search step. We score each result and do something with it. That's more or less how IBM Watson works.
