| − | 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, including:
| + | |
| − | * monovalent verbs ('sleep', 'rain')
| + | |
| − | * monovalent adverbs ('well', 'very')
| + | |
| − | * monovalent nouns ('arrival', 'construction')
| + | |
| − | * divalent verbs ('kill', 'kiss', 'depend')
| + | |
| − | * divalent adjectives ('loyal', 'interested')
| + | |
| − | * divalent prepositions and adverbs ('after', 'in', 'near', 'instead')
| + | |
| − | * trivalent verbs ('give', 'turn')
| + | |
| − | * trivalent prepositions ('between')
| + | |
| − | * etc.
| + | |
| − | | + | |
| − | == When not to use subcategorization frames ==
| + | |
| − | | + | |
| − | Subcategorization frames may not be used in case of words that take zero argument:
| + | |
| − | * avalent nouns ('table', 'computer')
| + | |
| − | * avalent adverbs ('here', 'now')
| + | |
| − | | + | |
| − | == Arguments and adjuncts ==
| + | |
| − | | + | |
| − | In the UNL framework, the subcategorization frame should be as small as possible, and should include only core arguments, in opposition to adjuncts.
| + | |
| − | | + | |
| − | == Syntax of generation rules ==
| + | |
| − | | + | |
| − | Subcategorization frames should be presented as a list of syntactic roles separated by semicolons. Each syntactic role must have the following format:
| + | |
| − |
| + | |
| − | <SYNTACTIC ROLE> ":=" "(" <SYNTACTIC FEATURES> ")" [, "(" <SYNTACTIC FEATURES> ")" ]* ";"
| + | |
| − | | + | |
| − | where
| + | |
| − | :<SYNTACTIC ROLE> = one of the three pre-defined syntactic roles (see below)
| + | |
| − | :<SYNTACTIC FEATURES> = the list of features required by the lemma
| + | |
| − | :[ ] = optional
| + | |
| − | :“ “ = constant
| + | |
| − | :<nowiki>*</nowiki> = to be repeated zero or more times
| + | |
| − | | + | |
| − | == Syntactic Roles ==
| + | |
| − | There are only three different types of syntactic roles:

| − | == Syntactic Features ==
| + | |
| − | The syntactic features must indicate:
| + | |
| − | * the selection for the syntactic category of the arguments (c-selection), if any
| + | |
| − | ** NP = Noun phrase
| + | |
| − | ** VP = Verbal phrase

| − | ** ACC = Accusative
| + | |
| − | ** DAT = Dative
| + | |
| − | ** ABL = Ablative

| − | ** LOC = Locative
| + | |
| − | * the agreement, if any
| + | |
| − | ** >NUM = Assigns number

| − | ** <NUM = Receives number

| − | ** >GEN = Assigns gender

| − | ** >PER = Assigns person

| − | ** <PER = Receives person
| + | |
| − | * the government, if any
| + | |
| − | ** the preposition required by the lemma

| − | | + | |
| − | == Other symbols ==
| + | |
| − | [Square brackets] may be used to indicate optional elements: a[b]c = ac, abc
| + | |
| − | | + | |
| − | {braces} may be used to indicate alternative elements: a{b,c}d = abd, acd

| − | | + | |
| − | === Verbs ===
| + | |
| − | *INTRANSITIVE ("sleep")
