Model Description
Gil Francopoulo, Monte George · 2013
This chapter describes the Lexical Markup Framework (LMF) abstract model and some simple examples. LMF targets two types of lexicon: lexicons specially designed for Natural Language Processing (NLP) and Machine-Readable Dictionaries (MRD). The ISO document of LMF contains two different types of content: the normative and the informative sections. Each LMF class is precisely defined and each Data Category Registry (DCR) constant has a precise definition. The core model is mandatory, and the extensions are optional. The link between entries of the same lexicon is possible at three different levels: in morphology by means of Related Form and in semantics by means of Sense Relation between Sense or by the use of a Synset instance to connect different Sense instances. The purpose of the multilingual notation extension is to describe the representation of equivalents for Sense or Syntactic Behaviour instances between or among two or more languages.
