Question-answering has become a popular task, with many practical applications (e.g. dialogue systems). It's appealingly easy to interpret and quantitatively evaluate, and with a simple setup, it's relatively easy to generate the very large datasets that work well for deep learning. Advancements in visual QA (with images and natural language questions) with large-scale datasets have pushed this field forward rapidly, and with this challenge dataset we hope to extend this progress to video. This dataset is a fill-in-the-blank version of the LSMDC2016 dataset - for more information about the datasets, please see here.
