We define the informativity of a host-verb bigram B as in Equation 5: where B is the bigram consisting of a host and a verb in either contracted or uncontracted form (for example, blood's or blood is), N is the total frequency of B, and next i is the following context word for the i th occurrence of B in the corpus.
the working hypothesis I have adopted contrasts strongly with that of the garden: Grammar itself is inherently variable and probabilistic in nature, rather than categorical and algebraic.
