ERG User Documentation
The English Resource Grammar (ERG) is a general-purpose computational grammar that, in combination with specialized processing tools, can map running English text to highly normalized logical-form representations of meaning.
An on-line demo of the ERG is available here.
- The most recent stable version of the ERG can be obtained via SVN:
$ svn checkout http://svn.delph-in.net/erg/tags/2018
- The latest ERG grammar files can be obtained via SVN:

Following are pointers to existing documentation on how to use the ERG, make sense of the syntactic and semantic analyses it provides, and interface to it for parsing or generation:

With high parsing accuracy with rich semantic representations, English Resource Semantics is a valuable source of information for many semantically-sensitive NLP tasks. ERS-based systems have achieved state-of-the-art results in various tasks, including the identification of speculative or negated event mentions in biomedical text (MacKinlay et al 2011), question generation (Yao et al 2012), detecting the scope of negation (Packard et al 2014), relating natural language to robot control language (Packard 2014), and recognizing textual entailment (PETE task; Lien & Kouylekov 2015). ERS representations have also been beneficial in semantic transfer-based MT (Oepen et al 2007, Bond et al 2011), ontology acquisition (Herbelot & Copestake 2006), extraction of glossary sentences (Reiplinger et al 2012), sentiment analysis (Kramer & Gordon 2014), and the ACL Anthology Searchbench (Schäfer et al 2011).
