N2 - This paper describes UIO, a multi--domain question--answering system for Czech language that looks for answers on the web. UIO exploits two fields, namely natural language interface to databases and question answering. In its current version, UIO can be used for asking questions about train and coach timetables, cinema and theatre performances, about currency exchange rates, name-days and on the Diderot Encyclopaedia. Much effort have been made into making addition of a new domain very easy. No limits concerning words or the form of a question need to be set in UIO. Users can ask syntactically correct as well as incorrect questions, or use keywords. A Czech morphological analyser and a bottom-up chart parser are employed for analysis of the question. The database of multiword expressions is automatically updated when a new item has been found on the web. For all domains UIO has an accuracy rate about 80%.
