When a user classifies a drawing like the following one (10 strokes)
as the formula \sum_{i=0}^{n} i^{2}, the system should be able to infer the following:
the different symbols involved (\sum, i, =, 0, i, 2)
the mapping of strokes to symbols (stroke 1 = sum, stroke 2 and 3 = i, ...) - this already includes the segmentation, but is more than only segmentation
the geometry (i=0 is below \sum, n is above \sum, i is right of \sum, 2 is above i)
