This is a complicated question, but the short answer is that by using natural language processing techniques (NLP) you can do this. The guy who knows the most about this is @Christophe_Willemsen. I'm not sure the best article of his to link to for this question (maybe he will stop by and drop the right one. 😉
Christophe has done some cool work with Alexa and other technologies where they have basically this problem: user says something, and we need to turn it into the right cypher queries to get answers. This might be a useful starting point.
But on the GraphAware NLP blog, there are going to be a number of resources to this topic.
