Abstract
Search engines, with Google at the top, have many remarkable capabilities. But what is not among them is the deduction capability — the capability to synthesize an answer to a query by drawing on bodies of information which are resident in various parts of the knowledge base. It is this capability that differentiates a question-answering system, Q/A system for short, from a search engine.
