Relation Schema Induction using Tensor Factorization with Side Information
Table 6: RSI accuracy comparison of SICTF with its ablated versions when no relation side information is used (λrel = 0), when no NP side information is used (λnp = 0), when no side information of any kind is used (λrel = 0, λnp = 0), and when additionally there are no non-negative constraints. From this, we observe that additional side information improves performance, validating one of the central thesis of this paper. Please see Section 4.3.2 and Section 4.3.3 for details.

In order to evaluate this thesis further, we compare performance of SICTF with its ablated versions: (1) SICTF (λrel = 0), which corresponds to the setting when no relation side information is used, (2) SICTF (λnp=0), which corresponds to the setting when no noun phrases side information is used, and (3) SICTF (λrel = 0, λnp=0), which corresponds to the setting when no side information of any kind is used. Hyperparameters are separately tuned for the variants of SICTF. From this, we observe that additional coupling through the side information significantly helps improve SICTF performance. This further validates the central thesis of our paper.
