Here we extract only the relation names: Here we take condition sequences as an example to describe the details of the method.
when predicting the j-th tag sequence, we define the position embedding of the i-th token as follows, representing the relative position to the j-th relation name's tag "B-c2p": the tag probability distributions of the i-th token in the condition tag sequences are: Similarly, we have the following tag distributions for the i-th token in the fact tag sequences: where v f i,j is the position embedding of the i-th token in the j-th fact sequence, representing the relative position to the relation name's tag "B-f2p".
