In NLP Punctuation Ambiguity or Siamese Sentences is part of the Milton Model. Punctuation Ambiguity is a bit harder to detect than the previous sets in the Indirect Elicitation Patterns. Punctuation ambiguity is identified as where you use a sequence of words which is the result of an overlap of two well-formed Surface Structures sentences sharing a word or phrase. In other words, take two sentences, one that ends with the same word as the second sentence begins. For example sentence one: “I want you to notice your hand” and sentence two: “Hand me the glass”. Now comes the trick. Make sentence one and two as one sentence and remove the “Hand” from the second sentence. You will get “I want you to notice your hand me the glass”. Simple right?!
