Argument structure and its realization 2/21/2005 Nianwen Xue
outline • • • Syntactic argument vs semantic argument Selectional restriction Subject control Object control Raising
Semantic valency • Arguments can be viewed as central participants in a situation w Aous laughed. Aous = the entity that does the laughing w Chris invited Dave. Chris = host Guest = Dave
Semantic valency • One-place predicates w Laugh, smile, • Two-place predicates w Invite, hit, • Three-place predicates w give, send, etc. • Four-place predicates w Accompany, • Five-place predicates w Rent,
Arguments defined in the frame files • http: //verbs. colorado. edu/framesets w w Smile Invite Accompany Rent
Syntactic argument (transitivity) • Arguments that are actually realized w Intransitive: takes one argument w Transitive: takes two arguments w Ditransitive: takes three arguments
Transitive to intransitive w He / interrupted / the meeting. He / interrupted. w Amy / knits / sweaters. Amy / knits. w They / are reading / a book. They / are reading.
Intransitive to transitive w Dennis / died / a peaceful death. w Lukas / laughed / an infectious laugh. w Mona Lisa / was smiling / a mysterious smile.
Ditransitive-intransitive w We teach college students syntax. We teach college students. We teach syntax. We teach. w He told me the whole story. He told me. He told the whole story. He better not tell.
Transitive to ditransitive w I baked a delicious cake. I baked my friends a delicious cake. w The lions killed a gazelle. The lions killed themselves a gazelle. w She sang a lullaby. She sang her baby a lullaby.
Alternation • Transitive to intransitive • Object to subject w Aous broke the window. w The window broke. • Changes of (syntactic) arguments • Change of position Levin (1993)
Syntax/semantics mismatch • Semantic arguments are not always explicitly realized • Realized syntactic arguments are not necessarily semantic arguments • Semantic arguments are not always realized in the same syntactic positions
Modification • Properties of events, which are less central, are often realized as modifiers: w w w w Manner: He read the letter carefully. Point in time: They discussed the proposal in the afternoon. Duration: You should keep your tax records for several years. Frequency: I read the Times quite often. Location: We met in my office. Origin: We set out from Bangalore. Destination: We arrived in Benares. Cause: He threw it away out of spite. w Purpose: I sent the message to warn everyone.

Pleonastic ‘there’ • Several vexing questions remain. There remain several vexing questions. • There is a clean shirt right here. There is a clean shirt over there. • * Remain several vexing questions.
Selectional restrictions • Amy drank the { lemonade, #sandwich } Lukas drank a whole { quart, #piece } • { Two hours, #the shift, #two liters, #Larry } elapsed without further incident. • The { paramilitary, #bomb, #avalanche } murdered { her husband, #the olive tree, #her house }. • The { paramilitary, bomb, avalanche } killed { her husband, the olive tree, #her house }.

agree (3) • The children agreed [*PRO* to get wet ]. # The { horses, trees, rocks } agreed [*PRO* to get wet] . • The children agreed [*PRO* to speak Twi ]. # The children agreed [*PRO* to { elapse, evaporate } ]. • The subject control verb and the lower verb impose separate selectional restrictions on their subject. • Therefore two clauses
Representing subject control structure S NP-1 VP S VV NP VP TO VP The children agreed *PRO*-1 to get wet.
Properties of subject control • *PRO* can’t be replaced with an overt NP • *PRO* must be coreferential with the subject NP in the matrix clause
Arbitrary *PRO* • [*PRO* to err] is human. • [*PRO* to forgive] is divine.

Seem (1) • The children seemed [ to dance ]. • * There agreed to be a problem. ok There seemed to be a problem. • The children agreed [ PRO to get wet ]. # The { horses, trees, rocks } agreed [ PRO to get wet ]. • ok The children seemed to get wet. ok The { horses, trees, rocks } seemed to get wet.
Seem (2) • Subject idiom chunks w # The cat agreed [ PRO to be out of the bag ]. w [The cat]i seems [ ti to be out of the bag ]. • Weather it: w # It agreed to be raining. w It seems to to be raining. Seem does not impose selectional restrictions

Representing raising S VP NP-1 S VBP NP-1 TO VP VP VB The children seems *-1 to dance.
Representing raising S VP NP VBP VP VP TO VB There seems to be NP a problem.
Properties of raising verbs • Do not impose selectional restrictions on its subject. Selectional restrictions on its subject imposed by the lower verb • Are not associated with a thematic role
