added, and a random number in the range from I to the
total sum is generated to determine which candidate should
be selected.
4.1.5. Word Generator ~WOR-GEN). This procedure finds
all possible candidates which satisfy the restrictions
specified in s restriction pattern, and assigns different
weights to them on the basis of the contents of a proba-
bility reweighting table. It selects a word st random
from the candidates according to their weights.
4.1.6. .Random Number Generator ~RA .NDOM). Input to
this procedure is an integer No This procedure generates
a random integer in the range from i to N.
4°2. The Generation Al~orithm
The general strategy for generating a paragraph is,
first, to generate the initial sentence based on a selected
restriction pattern, and then to generate each noninitial
sentence base not only on a selected restriction pattern
but also on the semantic properties of the words in all
the previously generated sentences of the paragraph. The
algorithm and the sentence generation procedure can best be
illustrated by an example. Let us suppose that the restric-
tion pattern shown in Fig. 4(a) is chosen for a sentence.
For ease of reference we will letter, the steps involved in
this procedure.
a. If the restriction pattern specifies a restriction
on the selection of the sentence governor (usually a tzars-
