This paper proposes OpenKI to handle sparsity of OpenIE extractions by performing instance-level inference: for each entity, it is proposed to encode the rich information in its neighborhood in both KB and OpenIE Extractions, and leverage this information in relation inference by exploring different methods of aggregation and attention.

This paper uses efficient truncated randomized search in this reward function to train structured prediction energy networks (SPENs), which provide efficient test-time inference using gradient-based search on a smooth, learned representation of the score landscape, and have previously yielded state-of-the-art results in structured prediction.
