121Firstly, according to him, semantic roles had fallen short of providing the detailneeded for semantic description and it was necessary to account for larger cognitivestructures capable of providing a new layer of semantic role notions in terms of whichwhole domains of vocabulary could be semantically characterized (Fillmore 1982: 115).Secondly, it was the combination of semantic roles which allowed him to describeparticular categories of situation. As a result, he realized eventually that the situationtypes themselves were what should be known as frames and that the case roles orsemantic roles within them should be identified relative to the frames. For instance,consider group A of sentences (Fillmore 1982: 115-116):Group A[1] Carla bought a bicycle from Pete for 50$.[1] Carla bought a bicycle from Pete.[3] Carla bought a bicycle for 50$.[4] Carla bought a bicycle.[5]*Carla bought from Pete for 50$.[6]*Carla bought from Pete.[7]*Carla bought for 50$.Based on the theory of cases, the verb to buy is said to have four deep cases. Thecases and their roles can be identified by analyzing group A of sentences and labels arechosen to account for the interaction between the verb and its arguments:Carla (Agent?) bought a bicycle (Theme?) from Pete (Source? Counteragent?).Now consider Table 7. The role labels are chosen by appealing to the conceptualbackground that underlies the meaning of the verb to buy, i.e. when somebody buyssomething this involves a buyer, a seller, goods and money.
