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.

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.
