The aim of the lexicon model for ontologies (lemon) is to provide rich linguistic grounding for ontologies. Rich linguistic grounding includes the representation of morphological and syntactic properties of lexical entries as well as the syntax-semantics interface, i.e. the meaning of these lexical entries with respect to an ontology or vocabulary.
Lemon consists of a core model (ontolex) and modules for syntax and semantics (synsem), decomposition (decomp), variation and translation (vartrans), and linguistic metadata (lime).
