An example of argument-head polysemy disambiguation 224 are the monotransitive verbs tirar and pôr. A common translation into Danish is ‘trække’ (tirar, ‘pull’) and ‘sætte’ (pôr, ‘put’), but with direct objects of the class (clothes), the translation is ‘tage af’ [take off] and ‘tage på’ [put on], respectively. Which translation is chosen, depends on the discriminator and whether or not it has been removed by a CG-rule like the following: REMOVE (@%+ACC-tøj) (*1 @) ; In terms of (polysemy) disambiguation gain by selection restrictions, head-argument disambiguation 225 is probably more important than argument-head disambiguation, since the latter - as opposed to the former - can also draw on the valency tag instantiation technique (cp. chapter 6.5.3) which is a very efficient tool. In the present grammar, (semantic) head-argument disambiguation is most advanced for subjects. For instance, the H/h atomic feature is disambiguated in subjects by checking for a matching V-HUM main verb. REMOVE (@=H) (0 @SUBJ>) (*1 @MV BARRIER CLB-ORD LINK 0 V-NON-HUM-SAFE OR V- NON-HUM) ; REMOVE (@=H) (0 @SUBJ>) (*1 CLB-ORD/VFIN LINK 0 CLB-ORD LINK *1 @MV LINK *1 @MV LINK 0 V-NON-HUM-SAFE OR V-NON-HUM) ; REMOVE (@=h) (0 @SUBJ>) (*1 @MV LINK 0 V-HUM-SAFE LINK NOT *-1 CLB-ORD) ; REMOVE (@=h) (0 @SUBJ>) (*1 CLB-ORD/VFIN LINK 0 CLB-ORD LINK *1 @MV LINK *1 @MV LINK 0 V-HUM-SAFE) ; Another case of head-argument reasoning are rules stating that MOVE-verbs (correr, viajar) need +MOVING subjects (feature I), and transitive MOVE-verbs (carregar, levar) need +MOVABLE direct objects (feature J): REMOVE (@=i) (0 @SUBJ> AND @=I) (*1 @MV BARRIER CLB-ORD LINK 0 V-MOVE); REMOVE (@=i) (0 @SUBJ>) (*1 @MV LINK 0 V-MOVE LINK NOT *-1 CLB-ORD) ; REMOVE (@=i) (0 @SUBJ>) (*1 CLB-ORD/VFIN LINK 0 CLB-ORD LINK *1 @MV LINK *1 @MV LINK 0 V-MOVE) ; REMOVE (@=j) (0 @
for every preposition. Though some solutions have been suggested for monolingual polysemy mapping of prepositions (like the Zeugma-test in Togeby [1993]), I have decided to treat preposition polysemy from a bilingual lexical point of view, defining “meaning” as the [Danish] translation of a preposition. The preposition sobre , for instance, is unlikely to mean ‘om’ in Danish if its head is not a cognitive verb, and its literal “physical” meaning ‘på’ is unlikely if its argument is not an entity, and this could be expressed by CG-rules like the following: (a) *REMOVE (@om) (0 PRP-SOBRE LINK 0 @
