Example Programs with ETS
The examples in this section have to do with trigram generation. This is a nice “show-off” program that demonstrates the power of the ETS tables.
Our goal is to write a heuristic program that tries to predict whether a given string is an English word.
To predict whether a random sequence of letters is an English word, we’ll analyze which trigrams occur in the word. A trigram is a sequence of three letters.
