11. Answer Type Identifier found?
Means we need to engage the user into the dialog in order to identify the answer type

15. Evaluation Subset of the Mooney GeoQuery dataset: 250 questions
we have manually labelled the focus/ATI/answer type for each question and then measured correctness of identifying
the focus/Answer Type Identifier (no ontology-based lookup involved)
correctness of consolidation algorithm: whether the Answer Type was identified correctly
