Hi,

In the Sentence Window Retrieval section, towards the end when we compare the results of window sizes 1,3 & 5 we see that the window size 1 has used most number of tokens. Why is this, this is counterintuitive. Size 5 should use most number of tokens right ? Attached is a snapshot of the results I am referring to please.
