Farima Fatahi Bayat, Nikita Bhutani, H.V. Jagadish

TL;DR
CompactIE is a neural-based OpenIE system that produces more compact, overlapping extractions, improving downstream utility and achieving state-of-the-art performance by detecting and linking constituents.
Contribution
We introduce CompactIE, a novel pipelined neural approach for extracting compact, overlapping facts, trained on processed benchmarks to enhance extraction utility.
Findings
Finds 1.5x-2x more compact extractions than previous systems
Achieves high precision and state-of-the-art performance on CaRB and Wire57 datasets
Improves downstream task utility through more concise extractions
Abstract
A major drawback of modern neural OpenIE systems and benchmarks is that they prioritize high coverage of information in extractions over compactness of their constituents. This severely limits the usefulness of OpenIE extractions in many downstream tasks. The utility of extractions can be improved if extractions are compact and share constituents. To this end, we study the problem of identifying compact extractions with neural-based methods. We propose CompactIE, an OpenIE system that uses a novel pipelined approach to produce compact extractions with overlapping constituents. It first detects constituents of the extractions and then links them to build extractions. We train our system on compact extractions obtained by processing existing benchmarks. Our experiments on CaRB and Wire57 datasets indicate that CompactIE finds 1.5x-2x more compact extractions than previous systems, with…
