Discrete Structural Constraints We experiment with two new tag schemes: (i) tag1:OA=OB, and (ii) tag2:OA =E=OB. Additionally, we experiment with removing the transition features from our CRF layer, though we still use structural constraints. Taken together, these results show that carefully capturing the domain constraints in how entities change over time is an important factor in our model.
