"The Australian Broadcasting Corporation (ABC)" abbrev(Corporation, ABC) adjectival complement An adjectival complement of a verb is an adjectival phrase which functions as the complement (like an object of the verb). "She looks very beautiful" acomp(looks, beautiful) adjectival modifier An adjectival modifier of an NP is any adjectival phrase that serves to modify the meaning of the NP. "Sam eats red meat" amod(meat, red) adverbial clause modifier An adverbial clause modifier of a VP or S is a clause modifying the verb (temporal clause, consequence, conditional clause, etc.). "The accident happened as the night was falling" advcl(happened, falling) "If you know who did it, you should tell the teacher" advcl(tell, know) adverbial modifier An adverbial modifier of a word is a (non-clausal) adverb or adverbial phrase (ADVP) that serves to modify the meaning of the word. "Genetically modified food" advmod(modified, genetically) "less often" advmod(often, less) agent An agent is the complement of a passive verb which is introduced by the preposition "by" and does the action. "The man has been killed by the police" agent(killed, police) "Effects caused by the protein are important" agent(caused, protein) appositional modifier An appositional modifier of an NP is an NP immediately to the right of the first NP that serves to define or modify that NP. It includes parenthesized examples. "Sam, my brother" appos(Sam, brother) "Bill (John's cousin)" appos(Bill, cousin) argument attributive An attributive is a WHNP complement of a copular verb such as "to be", "to seem", "to appear". "What is that?" attr (is, What) auxiliary An auxiliary of a clause is a non-main verb of the clause, e.g. modal auxiliary, "be" and "have" in a composed tense. "Reagan has died" aux(died, has) "He should leave" aux(leave, should) clausal complement with external subject open clausal complement An open clausal complement (xcomp) of a VP or an ADJP is a clausal complement without its own subject, whose reference is determined by an external subject. These complements are always non-finite. The name xcomp is borrowed from Lexical-Functional Grammar. "He says that you like to swim" xcomp(like, swim) "I am ready to leave" xcomp(ready, leave) clausal complement with internal subject A clausal complement of a verb or adjective is a dependent clause with an internal subject which functions like an object of the verb, or adjective. Clausal complements for nouns are limited to complement clauses with a subset of nouns like "fact" or "report". We analyze them the same (parallel to the analysis of this class as "content clauses" in Huddleston and Pullum 2002). Such clausal complements are usually finite (though there are occasional remnant English subjunctives). "He says that you like to swim" ccomp(says, like) "I am certain that he did it" ccomp(certain, did) "I admire the fact that you are honest" ccomp(fact, honest) clausal subject A clausal subject is a clausal syntactic subject of a clause, i.e., the subject is itself a clause. The governor of this relation might not always be a verb: when the verb is a copular verb, the root of the clause is the complement of the copular verb. In the two following examples, "what she said" is the subject. "What she said makes sense" csubj (makes, said) "What she said is not true" csubj (true, said) complement complementizer A complementizer of a clausal complement (ccomp) is the word introducing it. It will be the subordinating conjunction "that" or "whether". "He says that you like to swim" complm(like, that) element of compound number An element of compound number is a part of a number phrase or currency amount. "I lost $ 3.2 billion" number($, billion) conjunct A conjunct is the relation between two elements connected by a coordinating conjunction, such as "and", "or", etc. We treat conjunctions asymmetrically: The head of the relation is the first conjunct and other conjunctions depend on it via the conj relation. "Bill is big and honest" conj (big, honest) "They either ski or snowboard" conj (ski, snowboard) controlling subject A controlling subject is the relation between the head of a open clausal complement (xcomp) and the external subject of that clause. "Tom likes to eat fish" xsubj (eat, Tom) coordination A coordination is the relation between an element of a conjunct and the coordinating conjunction word of the conjunct. (Note: different dependency grammars have different treatments of coordination. We take one conjunct of a conjunction (normally the first) as the head of the conjunction.) "Bill is big and honest" cc(big, and) "They either ski or snowboard" cc(ski, or) copula A copula is the relation between the complement of a copular verb and the copular verb. (We normally take a copula as a dependent of its complement.) "Bill is big" cop(big, is) "Bill is an honest man" cop(man, is) dependent stanford Dependencies are established between tokens, i.e., exactly those entities that are subject to part of speech annotation. A dependency is labeled as dep when the system is unable to determine a more precise dependency relation between two words. This may be because of a weird grammatical construction, a limitation in the Stanford Dependency conversion software, a parser error, or because of an unresolved long distance dependency. "Then, as if to show that he could, . . . " dep(show, if) TODO: check tier (layer/level) identifier for stanford dependencies determiner A determiner is the relation between the head of an NP and its determiner. "The man is here" det(man, the) "Which book do you prefer?" det(book, which) direct object The direct object of a VP is the noun phrase which is the (accusative) object of the verb. "She gave me a raise" dobj (gave, raise) "They win the lottery" dobj (win, lottery) expletive (expletive “there”) This relation captures an existential "there". The main verb of the clause is the governor. "There is a ghost in the room" expl(is, There) indirect object The indirect object of a VP is the noun phrase which is the (dative) object of the verb. "She gave me a raise" iobj (gave, me) infinitival modifier An infinitival modifier of an NP is an infinitive that serves to modify the meaning of the NP. "Points to establish are . . . " infmod(points, establish) "I don't have anything to say" infmod(anything, say) marker (word introducing an advcl ) A marker of an adverbial clausal complement (advcl) is the word introducing it. It will be a subordinating conjunction different from "that" or "whether": e.g. "because", "when", "although", etc. "Forces engaged in fighting after insurgents attacked" mark(attacked, after) measure-phrase modifier modifier The multi-word expression (modifier) relation is used for certain multi-word idioms that behave like a single function word. It is used for a closed set of dependencies between words in common multi-word expressions for which it seems difficult or unclear to assign any other relationships. At present, this relation is used inside the following expressions: rather than, as well as, instead of, such as, because of, instead of, in addition to, all but, such as, because of, instead of, due to. The boundaries of this class are unclear; it could grow or shrink a little over time. "I like dogs as well as cats" mwe(well, as) mwe(well, as) "He cried because of you" mwe(of, because) negation modifier The negation modifier is the relation between a negation word and the word it modifies. "Bill is not a scientist" neg(scientist, not) "Bill doesn't drive" neg(drive, n't) nominal subject A nominal subject is a noun phrase which is the syntactic subject of a clause. The governor of this relation might not always be a verb: when the verb is a copular verb, the root of the clause is the complement of the copular verb, which can be an adjective or noun. "Clinton defeated Dole" nsubj (defeated, Clinton) "The baby is cute" nsubj (cute, baby) noun compound modifier A noun compound modifier of an NP is any noun that serves to modify the head noun. (Note that in the current system for dependency extraction, all nouns modify the rightmost noun of the NP -- there is no intelligent noun compound analysis. This is likely to be fixed once the Penn Treebank represents the branching structure of NPs.) "Oil price futures" nn(futures, oil) nn(futures, price) noun phrase as adverbial modifier This relation captures various places where something syntactically a noun phrase (NP) is used as an adverbial modifier in a sentence. These usages include: (i) a measure phrase, which is the relation between the head of an ADJP/ADVP/PP and the head of a measure phrase modifying the ADJP/ADVP; (ii) noun phrases giving an extent inside a VP which are not objects; (iii) financial constructions involving an adverbial or PP-like NP, notably the following construction $5 a share, where the second NP means "per share"; (iv) floating reflexives; and (v) certain other absolutive NP constructions. A temporal modifier (tmod) is a subclass of npadvmod which is distinguished as a separate relation. "The director is 65 years old" npadvmod(old, years) "6 feet long" npadvmod(long, feet) "Shares eased a fraction" npadvmod(eased, fraction) "IBM earned $ 5 a share" npadvmod($, share) "The silence is itself significant" npadvmod(significant, itself) "90% of Australians like him, the most of any country" npadvmod(like, most) numeric modifier A numeric modifier of a noun is any number phrase that serves to modify the meaning of the noun. "Sam eats 3 sheep" num(sheep, 3) object object of preposition The object of a preposition is the head of a noun phrase following the preposition, or the adverbs "here" and "there". (The preposition in turn may be modifying a noun, verb, etc.) Unlike the Penn Treebank, we here define cases of VBG quasi-prepositions like "including", "concerning", etc. as instances of pobj. (The preposition can be called a FW for "pace", "versus", etc. It can also be called a CC -- but we don't currently handle that and would need to distinguish from conjoined prepositions.) In the case of preposition stranding, the object can precede the preposition (e.g., "What does CPR stand for?"). "I sat on the chair" pobj (on, chair) parataxis The parataxis relation (from Greek for "place side by side") is a relation between the main verb of a clause and other sentential elements, such as a sentential parenthetical, or a clause after a ":" or a ";". "The guy, John said, left early in the morning" parataxis(left, said) participial modifier A participial modifier of an NP or VP or sentence is a participial verb form that serves to modify the meaning of a noun phrase or sentence. "Truffles picked during the spring are tasty" partmod(truffles, picked) "Bill tried to shoot demonstrating his incompetence" partmod(shoot, demonstrating) passive auxiliary A passive auxiliary of a clause is a non-main verb of the clause which contains the passive information. "Kennedy has been killed" auxpass(killed, been) aux(killed,has) "Kennedy was/got killed" auxpass(killed, was/got) passive clausal subject clausal passive subject A clausal passive subject is a clausal syntactic subject of a passive clause. In the example below, "that she lied" is the subject. "That she lied was suspected by everyone" csubjpass(suspected, lied) passive nominal subject A passive nominal subject is a noun phrase which is the syntactic subject of a passive clause. "Dole was defeated by Clinton" nsubjpass(defeated, Dole) phrasal verb particle The phrasal verb particle relation identifies a phrasal verb, and holds between the verb and its particle. "They shut down the station" prt(shut, down) possession modifier The possession modifier relation holds between the head of an NP and its possessive determiner, or a genitive 's complement. "their offices" poss(offices, their) "Bill's clothes" poss(clothes, Bill) possessive modifier (’s) The possessive modifier relation appears between the head of an NP and the genitive 's. "Bill's clothes" possessive(John, 's) preconjunct A preconjunct is the relation between the head of an NP and a word that appears at the beginning bracketing a conjunction (and puts emphasis on it), such as "either", "both", "neither"). "Both the boys and the girls are here" preconj (boys, both) predeterminer A predeterminer is the relation between the head of an NP and a word that precedes and modifies the meaning of the NP determiner. "All the boys are here" predet(boys, all) In the collapsed representation, a prepositional clausal modifier of a verb, adjective, or noun is a clause introduced by a preposition which serves to modify the meaning of the verb, adjective, or noun. "He purchased it without paying a premium" prepc_without(purchased, paying) missing in the taxonomy of de Maneffe & Manning (2011, §3) prepositional complement missing from the taxonomy de Maneffe & Manning (2011, §4) This is used when the complement of a preposition is a clause or prepositional phrase (or occasionally, an adverbial phrase). The prepositional complement of a preposition is the head of a clause following the preposition, or the preposition head of the following PP. "We have no information on whether users are at risk" pcomp(on, are) "They heard about you missing classes" pcomp(about, missing) prepositional modifier A prepositional modifier of a verb, adjective, or noun is any prepositional phrase that serves to modify the meaning of the verb, adjective, noun, or even another prepositon. In the collapsed representation, this is used only for prepositions with NP complements. "I saw a cat in a hat" prep(cat, in) "I saw a cat with a telescope" prep(saw, with) "He is responsible for meals" prep(responsible, for) punctuation This is used for any piece of punctuation in a clause, if punctuation is being retained in the typed dependencies. By default, punctuation is not retained in the output. "Go home!" punct(Go, !) purpose clause modifier A purpose clause modifier of a VP is a clause headed by "(in order) to" specifying a purpose. At present the system only recognizes ones that have "in order to" as otherwise the system is unable to distinguish from the surface representations between these and open clausal complements (xcomp). It can also recognize fronted "to" purpose clauses in sentences. "He talked to him in order to secure the account" purpcl(talked, secure) quantifier modifier quantifier phrase modifier A quantifier modifier is an element modifying the head of a QP constituent. (These are modifiers in complex numeric quantifiers, not other types of "quantification". Quantifiers like "all" become det.) "About 200 people came to the party" quantmod(200, About) referent A referent of the head of an NP is the relative word introducing the relative clause modifying the NP. "I saw the book which you bought" ref (book, which) relative (word introducing a rcmod ) A relative of a relative clause is the head word of the WH-phrase introducing it. This analysis is used only for relative words which are not the subject of the relative clause. Relative words which act as the subject of a relative clause are analyzed as a nsubj. "I saw the man whose wife you love" rel (love, wife) relative clause modifier A relative clause modifier of an NP is a relative clause modifying the NP. The relation points from the head noun of the NP to the head of the relative clause, normally a verb. "I saw the man you love" rcmod(man, love) "I saw the book which you bought" rcmod(book,bought) The root grammatical relation points to the root of the sentence. A fake node "ROOT" is used as the governor. The ROOT node is indexed with "0", since the indexation of real words in the sentence starts at 1. "I love French fries." root(ROOT, love) "Bill is an honest man" root(ROOT, man) semantic dependent subject temporal modifier A temporal modifier (of a VP, NP, or an ADJP is a bare noun phrase constituent that serves to modify the meaning of the constituent by specifying a time. (Other temporal modifiers are prepositional phrases and are introduced as prep.) "Last night, I swam in the pool" tmod(swam, night) abbrev acomp advcl advmod agent amod appos arg attr aux auxpass cc ccomp comp compl complm conj conj_ cop csubj csubjpass dep det dobj expl infmod iobj mark measure mod mwe neg nn npadvmod nsubj nsubjpass num number obj parataxis partmod pcomp pobj poss possessive preconj predet prep prep_ prepc prepc_ prt punct purpcl quantmod rcmod ref rel root sdep subj tmod xcomp xsubj
