Language resource management — Lexical markup framework (LMF) — Part 6: Syntax and semantics
This document specifies the syntax and semantics (SynSem) module of the lexical markup framework (LMF), a metamodel for representing data in monolingual and multilingual lexical databases used with computer applications. The SynSem module allows for the description of specific syntactic and semantic properties of lexemes, as well as the complex interactions between them. More specifically, the syntax part of the module describes the properties of a lexeme when combined with other lexemes in a sentence. When recorded in a lexicon, these properties make up the syntactic description of a lexical entry instance. The semantics part of the module, on the other hand, describes the sense of a lexeme and its relationship with other senses belonging to the same language. The SynSem interface describes the predicates and the mapping between syntactic and semantic arguments. This serialization covers the classes of ISO 24613-1 (Core model), ISO 24613-2 (Machine-readable dictionary (MRD) model) and ISO 24613-4 (TEI serialization).
Gestion des ressources linguistiques — Cadre de balisage lexical (LMF) — Partie 6: Syntaxe et sémantique
Le présent document spécifie le module syntaxe et sémantique (SynSem) du cadre de balisage lexical (LMF), un métamodèle permettant de représenter les données dans des bases de données lexicales monolingues et multilingues utilisées avec des applications informatiques. Le module SynSem permet de décrire les propriétés syntaxiques et sémantiques spécifiques des lexèmes, ainsi que les interactions complexes entre ces derniers. Plus précisément, la partie syntaxique du module décrit les propriétés d’un lexème lorsqu’il est combiné avec d’autres lexèmes dans une phrase. Lorsqu’elles sont enregistrées dans un lexique, ces propriétés constituent la description syntaxique d’une entrée lexicale. La partie sémantique du module, quant à elle, décrit le sens d’un lexème et sa relation avec les autres sens appartenant à la même langue. L’interface SynSem décrit les prédicats et la correspondance entre les arguments syntaxiques et sémantiques. Cette sérialisation couvre les classes de l’ISO 24613-1 (modèle de base), de l’ISO 24613-2 (modèle de dictionnaire lisible par ordinateur (MRD)) et de l’ISO 24613-4 (sérialisation TEI).

3.1
syntactic behaviour
one of the possible alternations that a lexeme can show, at the syntactic level
EXAMPLE A verb can have different types of syntactic behaviours for subcategorization frame (3.2) alternations,
such as the active voice, the passive voice, reflexive, etc.
[9][12]
Note 1 to entry: A syntactic behaviour is described in terms of subcategorization frames.
3.2
subcategorization frame
valence
valency
set of restrictions on a lexeme indicating the properties of the syntactic arguments (3.4) that can or must
occur with this given lexeme
3.3
semantic predicate
formal semantic unit that represents a semantic relation between one or more semantic arguments (3.5) in
a predicate-argument structure
[SOURCE: ISO 24617-4:2014, 2.1.2, modified — term “predicate” replaced by “semantic predicate”.
“argument” replaced by “semantic argument” within definition. Note 1 to entry deleted.]
3.4
syntactic argument
one of the essential and functional constituents in a clause that identifies the participants in the process
referred to by a lexeme
EXAMPLE Alfred (syntactic argument) reads a book (syntactic argument) today (adjunct).
3.5
semantic argument
formal semantic unit that is an essential constituent of a predicate-argument structure and can have variable
instantiations depending on the utterance

4 Description of the syntax and semantics module (SynSem) model
4.1 General principles of the SynSem model
The modelling of the syntactic and semantic properties of lexicons can differ considerably from lexicon to
lexicon, due to different linguistic theories.
[2]
The present modelling of syntax and semantics builds on the previous one, given in ISO 24613:2008 ,
which contained two sub-modules for syntax and semantics. In ISO 24613:2008, experts identified a
nucleus of elements that are sufficiently generic to constitute a common ground. The ISO 24613:2008
syntactic and semantics models were the basis for other modelling of the syntax/semantics interface, such
[13]
as the W3C Ontolex “Syntax and Semantics Module”. For these reasons, the overall structure of the
[11] [8]
previous model, which was used in various projects such as the PAROLE and SIMPLE projects, was
not changed in this document, but some simplifications/modifications were introduced. In particular, the
previous semantic module contained elements that were entirely dedicated to the modelling of WordNet-
like lexicons, introducing a Synset class. This is judged to be unnecessary in this document since the Sense
and SenseRelation classes can be used instead. Another difference with respect to ISO 24613:2008 is the
lack of a feat class, which was used to make up for specific elements which a lexicographer can potentially
want to introduce but which were not generic enough to be included in the model. In the present UML-
based standardization, only the core features of the syntax/semantics interface are described. However, the
lexicographer can extend the model to extend other features.
Figure 1 gives a class diagram for SynSem with the module specific classes in pink. Figure 2 shows the
subclasses of CrossREF (described in ISO 24613-1) which are referred to in the class diagram in Figure 1.
Figure 1 — SynSem module
Figure 2 — Subclasses of CrossREF
Regarding the modelling of syntax in Figure 1, a LexicalEntry may have one or more instances of
SyntacticBehaviour, associated with separate SubcategorizationFrame instances, each described with
SyntacticArgument. Regarding the modelling of semantics, it applies to senses. The Sense class is specified
in the core package. The Sense class is aggregated in the LexicalEntry class. A PredicativeRepresentation
serves to connect a Sense with one or more instances of SemanticPredicate, which are described in terms
of SemanticArgument instances. The linking between syntax and semantics is done by the SynSemArgMap
component, which links a SemanticArgument with a SyntacticArgument.
Clause A.1 illustrates the full model, using the French verb “aider” (“help”) with its syntactic and semantic
properties.

4.2.1 SyntacticBehaviour class
SyntacticBehaviour is a class representing one of the possible syntactic behaviours of a lexeme. It is a subclass
