Abstract

Existing logic-based querying tools for dependency treebanks use first order logic or monadic second order logic. We introduce a very fast model checker based on hybrid logic with operators ↓, @ and A and show that it is much faster than an existing querying tool for dependency treebanks based on first order logic, and much faster than an existing general purpose hybrid logic model checker. The querying tool is made publicly available.

Highlights

  • Existing logic-based querying tools for dependency treebanks use first order logic or monadic second order logic

  • We introduce a very fast model checker based on hybrid logic with operators ↓, @ and A and show that it is much faster than an existing querying tool for dependency treebanks based on first order logic, and much faster than an existing general purpose hybrid logic model checker

  • Our results show that our model checker is much faster than hybrid logic model-checker (HLMC), especially for formulas of considerable depth
