which it is expressed. The basic difference between semantic nets and CD lies
in the naming of the connecting links. In semantic nets, one may name the
connecting links between events according to its relevance to the context and
consequently the name differs for different users. A CD, on the other hand,
requires a standard assignment of a dependence relationship and is, therefore,
independent of the users. An English sentence and its corresponding CD
representation is presented below to visualize the issues discussed above.
Consider the sentence ‘She gave me a flower’. This is represented below in
fig. 8.15.
In the last figure, R denotes a recipient case relation, o denotes an object
case relation, p denotes past tense, denotes a two way link between the
actor and action and ATRANS stands for transfer of possession. It is called a
primitive action. The set of primitive actions in CD, proposed by Schank and
Abelson [10], is presented below.
