问答系统

The goal is to get a system to give answers to questions about the contents of a text – all in natural language. For example, there could be a document describing the life and habitat of a certain animal. You would then process the text and store various facts that it describes ("x eats ants" or eat(x, ants)). A user can then type a question ("what does x eat?") and the system would answer ("x eats ants"). It is fine to assume that the text is a basic text (maybe from a children’s book of knowledge).
