An Interface is an style and a great example of that style is the very said “natural language”. This style permits the contact and dialogue between human users and a computer. But we can say that sometimes the natural language is considered as too extreme fot the interface style to understand, so the user must learn which structures are correct.
The question answering is a system which has an interface style and is based on an inmediatly answer to a question on natural language. A computer with this system is pre-structured with an special database. This system is known for requiring really complex natural language processing, more than other information retrieval engines or searchers. There are some examples on the World Wide Web about this system of QA, for instance:
