The COCO-QA dataset<cite> (Ren et al., 2015)</cite> for VQA was created by parsing COCO captions with a syntactic parser, and then used this to create QA pairs for four kinds of questions using hand-crafted rules. However, due to inability of the algorithm to cope with complex sentence structures, a significant portion of COCO-QA questions have grammatical errors or are oddly phrased.
