In a departure from previous work in answer type detection (Krishnan et al., 2005;<cite> Li and Roth, 2002)</cite> , we have demonstrated how a large, multi-tiered answer type hierarchy can be created which incorporates many of the entity types included in LCC's wide coverage named entity recognition system, CICEROLITE; this hierarchy was then used in order to create a new corpus of more than 10,000 questions which could be used to train an ATD system.
