After mapping the Freebase types of Donald Trump to the target tag set, this sample will be weakly annotated as /person/politician, /person/tv personality, and /person/business, which is exactly the same as the type information (the "Types From KB" in Figure 1) obtained through EL.
during training, when the EL system links the mention to the correct entity, the model only needs to output the types in the KB type representation.
