This is the absolute number of shared fingerprints in the left and right file. These are not necessarily the same because a shared fingerprint might have a different number of occurrences in the left and right file.

A fingerprint is a series of$$k$$ subsequent tokens (k-grams) in the syntax tree selected out of a window of $$w$$ k-grams.
The similarity between two source files a and b is computed as
$$sim(a,b) = \frac{S_a + S_b}{T_a + T_b}$$ $$T_x$$ the total number of fingerprints in file $$x$$ and $$S_x$$ the number of fingerprints in file $$x$$ that also occur in the other file.
