Objections To Chaining Theory • Finite-state grammar • Transitional probabilities say nothing about meaning • Embedding • Ambiguous sentences
How would Chaining Theory explain the following sentence? “That man has eaten the bread.”
Possible sequences that can be generated from “words”, A, B & C: Without replacement: A B C A C B B A C B C A C A B C B A

Number of 3-word sentences = 33 = 27 Suppose we considered 10 word sentences. 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 = 310 = 59, 049 different sentences.
Suppose we arbitrarily restrict language to sentences of 10 words… • There are 450,000 English words • Number of 2-word sentences: (450,000)2 = 202,000,000,000 = 211 • Number of 3-word sentences: (450,000)3 = 91,125,000,000,000,000 = 9115. • Consider only grammatical sentences. • Assume only one in a million was grammatical. i.e., 106. • There would then be only 91,125, 000, 000 = 919 grammatical sentences. • Suppose we read one word/sec., reading at a rate of 24 hrs/day, 365 days/year, it would take 2,887 years to read all possible three-word sentences. Four-word sentences: 1,299,150,000 years.

DESCRIPTION OF TEST PICTURE: In this picture, a man has just run out of his house to remonstrate with a girl passerby, thinking that she must be responsible for his broken window. We also see a boy in baseball garb hiding behind a fence and can reasonably assume that he, not the girl, is the culprit.
