Scope-enhanced Compositional Semantic Parsing for DRT
Xiulin Yang, Jonas Groschwitz, Alexander Koller +1
Discourse Representation Theory (DRT) distinguishes itself from other semantic representation frameworks by its ability to model complex semantic and discourse phenomena through st…
AMR Parsing is Far from Solved: GrAPES, the Granular AMR Parsing Evaluation Suite
Jonas Groschwitz, Shay B. Cohen, Lucia Donatelli +1
We present the Granular AMR Parsing Evaluation Suite (GrAPES), a challenge set for Abstract Meaning Representation (AMR) parsing with accompanying evaluation metrics. AMR parsers n…
Learning compositional structures for semantic graph parsing
Jonas Groschwitz, Meaghan Fowlie, Alexander Koller
AM dependency parsing is a method for neural semantic graph parsing that exploits the principle of compositionality. While AM dependency parsers have been shown to be fast and accu…
Fast semantic parsing with well-typedness guarantees
Matthias Lindemann, Jonas Groschwitz, Alexander Koller
AM dependency parsing is a linguistically principled method for neural semantic parsing with high accuracy across multiple graphbanks. It relies on a type system that models semant…
Graphs with Multiple Sources per Vertex
Martin van Harmelen, Jonas Groschwitz
Several attempts have been made at constructing Abstract Meaning Representations (AMRs) compositionally, and recently the idea of using s-graphs with the HR-algebra (Koller, 2015)…
Normalizing Compositional Structures Across Graphbanks
Lucia Donatelli, Jonas Groschwitz, Alexander Koller +2
The emergence of a variety of graph-based meaning representations (MRs) has sparked an important conversation about how to adequately represent semantic structure. These MRs exhibi…
Compositional Semantic Parsing Across Graphbanks
Matthias Lindemann, Jonas Groschwitz, Alexander Koller
Most semantic parsers that map sentences to graph-based meaning representations are hand-designed for specific graphbanks. We present a compositional neural semantic parser which a…
AMR Dependency Parsing with a Typed Semantic Algebra
Jonas Groschwitz, Matthias Lindemann, Meaghan Fowlie +2
We present a semantic parser for Abstract Meaning Representations which learns to parse strings into tree representations of the compositional structure of an AMR graph. This allow…
Sharp thresholds for half-random games II
Jonas Groschwitz, Tibor Szabó
We study biased Maker-Breaker positional games between two players, one of whom is playing randomly against an opponent with an optimal strategy. In this work we focus on the case…
Sharp thresholds for half-random games I
Jonas Groschwitz, Tibor Szabó
We study biased Maker-Breaker positional games between two players, one of whom is playing randomly against an opponent with an optimal strategy. In this paper we consider the scen…
