sitive verb (VT) or an intransitive verb (VI)), a VT or
VI will be randomly chosen from the specified semantic
class(as) or word(s). Otherwise a VT or VI will be randomly
chosen. In our example the restriction pattern in Fig. 4(a)
specifies that a word should be selected from the word
class VT which is not a member of the semantic e[eeBes
CI, C2, and C3, but is a governor of a word in C16, a
word in word class N. and a word in C19. (Note also that
the sentence should not contain a sentence adverb.)
There are 16 candidates which satisfy the restrictions.
They are shown in Fig. 4(b) by their addresses, at which
word numbers are stored. A random number is generated in
the range i to 16, for example, 8. Thus the eighth VT is
chosen: word number 3336 whose address is 531.
b. The possible dependent types of a VT are NS
(noun subject), NO (noun object), DV (adverb), and DS
(sentence adverb). The probabilities (in percentages) for
the word 3336 to govern words of these dependent types
are, say, 65, i00, 35, and 40 respectively. The procedure
RELATOR is called in order to determine whether the selec-
tion of each dependent type agrees with the restriction
pattern. If the selection of a dependent type conflicts
with the pattern, the dependent type is ignored, i.e., no
word will be selected from this dependent type as the
dependent of the verb 3336. In our example, NS, NO, and
DV have passed this test.
