The need for natural language interfaces to databases (NLIDBs) has become more acute as more nontechnical people access information through their web browsers, PDAs, and cell phones. Yet NLIDBs are only useful if they map natural language questions to SQL queries correctly, and natural language interfaces tend to be error-prone.

The PRECISE Natural Language Interface to Databases is designed on the principle that it should guarantee the correctness of its output, or else indicate that it does not understand the input question. For a certain class of semantically tractable questions, PRECISE is able to recognize a member of that class and guarantee that its SQL output is the correct interpretation of the question.
