Our experiments with ALICE indicate that the number of choices for the “first word” is more than ten, but it is only about two thousand. Specifically, 1800 words covers 95% of all the first words input to ALICE. The number of choices for the second word is only about two. To be sure, there are some first words (“I” and “You” for example) that have many possible second words, but the overall average is just under two words. The average branching factor decreases with each successive word.
