    Abstract

    We investigate the problem of complex answers in question answering. Complex answers consist of several simple answers. We describe the online question answering system shapaqa, and using data from this system we show that the problem of complex answers is quite common. We define nine types of complex questions, and suggest two approaches, based on answer frequencies, that allow question answering systems to tackle the problem.
