the hypernyms of the word are stored. Word 613 is a 
hypernym of the word 2466. Thus, H is set to 17 which is 
the location in table (5) where a counter and the word 613 
are stored. Since the word 2466 is a member of the seman- 
tic class C47, the pointer S associated with the word 2466 
is set to the location in table (6) where a counter and 
C47 is stored. 
Table (3) contains 74 blocks, which are reserved for 
the 74 semantic classes established in the system. Each 
block contains a counter and the addresses of the words 
in a semantic class. For example, the address 309 is 
stored in the 47th block in tBble (3). Table (3) is thus 
linked to table (I). 
After all data have been entered in the tables, the 
word numbers (positive values) in tsbles (4) and (5) are 
replaced by their addresses in table (i). This operation 
is done by using the lookup table (2). 
The data are organized in tables with associative 
links. All word numbers in tables (3), (4), and (5) are 
replaced by their addresses in table (i). From an entry 
in table (I) (where the generation of a sentence usually 
begins), we can trace its possible dependents; since these 
dependents are specified as pointers to their addresses in 
i 
table (I), it is simple to obtain the lists of dependents 
associated with these dependents. In turn we can trace third 
level dependent lists. We can easily continue this operation
