The Universal Decompositional Semantics Dataset and Decomp Toolkit
This work addresses the need for a unified semantic graph resource for NLP researchers, though it is incremental as it builds on existing annotation sets.
The authors tackled the problem of fragmented semantic annotation by unifying five decompositional semantics datasets into the Universal Decompositional Semantics (UDS) dataset and providing the Decomp toolkit for querying, making these resources publicly available.
We present the Universal Decompositional Semantics (UDS) dataset (v1.0), which is bundled with the Decomp toolkit (v0.1). UDS1.0 unifies five high-quality, decompositional semantics-aligned annotation sets within a single semantic graph specification---with graph structures defined by the predicative patterns produced by the PredPatt tool and real-valued node and edge attributes constructed using sophisticated normalization procedures. The Decomp toolkit provides a suite of Python 3 tools for querying UDS graphs using SPARQL. Both UDS1.0 and Decomp0.1 are publicly available at http://decomp.io.
