In the UNL framework, '''Subcategorization Frames''' are the number and types of syntactic arguments that co-occurs with the lemma in a sentence.

#REDIRECT [[Subcategorization frames]]
 
+
== When to use subcategorization frames ==
+
 
+
Subcategorization frames are mandatory for words that take one or more syntactic argument, such as:
+
* intransitive verbs ('sleep', 'rain')
+
* direct transitive verbs ('kill', 'kiss')
+
* indirect transitive verbs ('depend', 'rely')
+
* ditransitive verbs ('give')
+
* deverbals ('arrival', 'construction')
+
* adjectives that require a complement ('loyal to', 'interested in')
+
* adverbs that require a complement ('contrarily to')
+
* prepositions ('in', 'after', 'near', 'instead')
+
* conjunctions ('because', 'and', 'but')
+
* proper nouns that require an article ('The United States of America")
+
 
+
Subcategorization frames are optional for words that take no syntactic argument, such as:
+
* nouns ('table', 'computer')
+
* adjectives ('beautiful', 'intelligent')
+
* adverbs ('yesterday', 'here')
+
* determiners ('the', 'this')
+
* pronouns ('he', 'yours')
+
 
+
== Syntax ==
+
 
+
Subcategorization frames should comply with the '''[[S-Rule]]''' formalism for writing syntactic rules in the UNL framework.

== Observations ==

+
'''Syntactic case marking''' can be associated to the arguments of syntactic relations, if necessary.
+
*VS(NP),VC(NP); (the verb has a specifier (NP) and a complement (NP), i.e., is a direct transitive verb (without syntactic case marking)
+
*VS(NP,NOM),VC(NP,ACC); (the verb as a specifier (NP) that receives the nominative (NOM) case and a complement (NP) that receives the accusative (ACC) case
+
;Syntactic case marking should be avoided if default (i.e., if already expressed in the language settings)
+
:If the specifier of the verb always receives a nominative case, this information should be stated in the [[language settings]] and not in individual subcategorization frames
+
*Subcategorization frame: VS(NP); (the specifier of the verb is a noun phrase)
+
*Language settings: VS(NP):=VS(NP,NOM); (every NP specifier of the verb receives the nominative (NOM) case)
+
'''Agreement''' information can be associated to the arguments of syntactic relations, if necessary.
+
*VS(NP); (the specifier of the verb is a noun phrase and there is no information on agreement
+
*VS(NP,ANUM,APER); (the specifier of the verb is a noun phrase (NP) that assigns number (ANUM) and person (APER) to its head);
+
;Agreement information should be avoided if default (i.e., if already expressed in the language settings)
+
:If the specifier of the verb always assigns number and person to its head this information should be state in the [[language settings]] and not in individual subcategorization frames
+
*Subcategorization frame: VS(NP); (the specifier of the verb is a noun phrase)
+
*Language settings: VS(NP):=VS(NP,ANUM,APER); (every NP specifier of the verb assigns number and person to its head)
