There are four pointers associated with each word 
stored in table (I). Pointer D specifies the location in 
table (4) where the list of dependents associated with 
the word is stored. A countez is used to specify the 
number of words and semantic classes in the list. A 
semantic class in the original data is prefixed by a C 
(CI identifies senmntic class I). In table (4) all the 
counters and semantic classes (the numerical values) are 
stored as negative values so that the positive values 
(i.e. word numbers) can be conveniently changed to pointers 
at a later stage. In our example the pointer D is 130 
and the words 726 and 4594, and also the semantic classes 
CI, C2 and C16, are in the dependent list associated with 
word 2466. The value which identifies a semantic class in 
table (4) is actually a pointer to a table which contains 
the starting locations of the lists of words in all senmr~- 
tic classes. This is illustrated in Fig. I by the links 
from table (4) through table (8) to table (3). 
The set of governing probabilities associated with 
word 2466 is stored in table (7). Pointer P specifies the 
starting location where the probability values are stored. 
In the example, P is set to 142. Notice that no spaces 
are reserved for adjectives and adverbs bocauae they do 
not have governing probabilities. 
The pointer H associated with a word in table (I) 
specifies the location in table (5) where a counter and
