In this paper we present a prototype implementation of the question answering system for one of the inflectional languages - Czech. The presented open domain system is especially effective in answering factual wh-questions about people, dates, names and locations. The answer is constructed on-thefly from data gathered from the Internet, public ontologies, knowledge of the Czech language, and extensible template system. The system is capable of semiautomatic learning of new templates as well as both statistical and semantic processing of Internet content.
