About relation F1 about pure HOT 1 CLOSED

Hi! n_gold and e2e_ngold can be different. e2e_ngold is the number of all gold relations; while n_gold is the number of gold relations that are considered as a candidate by the relation model.
Note that some gold relations won't be considered as a candidate, because the entity model may not extract all entities.

Here is an example.
In one sample, there are two gold relational triples (e1, r1, e2), (e2, r2, e3). Here, e2e_ngold=2. If the entity model only correctly extracts entities e1 and e2, we will have n_gold=1.

F1 is computed using e2e_ngold; task_F1 is computed using n_gold and it is the F1 score if we evaluate the relation classification task individually.
