These are the 43 GIF categories. These categories correspond to the 43 categories suggested by Twitter when a user responds with a GIF. Note that any GIF can belong to multiple categories. Thus, the label in the dataset is a non-empty subset of 1 to 6 categories.
To create the gold labels, we checked each GIF for its inclusion in the GIFs suggested by Twitter. The categories in which the GIF appears are the gold labels. We examined the top 100 GIFs suggested by Twitter in each category.
