The Semantic Constructor computes a flat semantic representation of a sentence using a TAG grammar equipped with a syntax / semantics interface (e.g., a TAG compiled with XMG).
It uses the DyALog system developed by Éric De La Clergerie at INRIA Rocquencourt to perform syntactic parsing. The derivation forest output by DyALog is then used to compute the semantic representation using the technique given in  .
This software is being used to perform an evaluation of the SemFRAG (semantic French TAG grammar) of  in terms of semantic coverage of the Test Suite for NLP.
