This paper presents a computational resource for exploring semantic parsing and reasoning through a strictly formal lense. Inspired by the framework of Lexical Functional Grammar, our system allows for modular exploration of different aspects of semantic parsing. It consists of a hand-coded formal grammar combining syntactic and semantic annotations, producing basic semantic representations. The system provides the option to extend these basic semantics via rewrite rules in a principled fashion to explore more complex reasoning. The result is a layered system enabling an incremental approach to semantic parsing. We illustrate this approach with examples from the Fracas testsuite demonstrating its overall functionality and viability.

Computational Semantics Tools for Glue Semantics

Proceedings of the 16th International Conference on Computational Semantics

This paper introduces a suite of computational semantic tools for Glue Semantics, an approach to compositionality developed in the context of Lexical Functional Grammar (LFG), but applicable to a variety of syntactic representations, including Universal Dependencies (UD). The three tools are: 1) a Glue Semantics prover, 2) an interface between this prover and a platform for implementing LFG grammars, and 3) a system to rewrite and add semantic annotations to LFG and UD syntactic analyses, with a native support for the prover. The main use of these tools is computational verification of theoretical linguistic analyses, but they have also been used for teaching formal semantic concepts.
