Notizen: We have developed a prototype of a question-answering system which is intended to interact with an untrained user to give him information about the Yellow Pages of the French phone directory. We don't detail here the description of the system, because it is done in another paper in the same issue: “A question-answering system for the French Yellow Pages”.In this paper we first present a typology of the different kinds of unforeseen situations the system may have to handle while interacting with an untrained user. Then, we detail different strategies we have developed to solve these problems, more specifically to correct misspelt words and to deal with the properly typed, but unknown, words. These mechanisms have been integrated into the parser, and try to maintain, as long as possible, its determinism.
