Question about the directional information

[yrcong]

Hi Jingwei,

thanks for your work! I have a question about the direction in the scene graph. In other scene graph dataset like VG, the relations are annotated as triplet subject-relation-object. I see in the action genome the relation labels are associated with objects. So how did you define the direction when evaluating Re@X? I also find some opposite relations appear at the same time e.g. {'class': value, 'bbox': value, 'spatial_relationship': ['in front of', 'behind']}. I guess it means human-in front of-object and object-behind-human (or opposite). How can we get this info? Waiting for your reply!

Thanks a lot

same question. Or is the graph for this dataset an Undirected graph?
