Additional Language Features

Semantic grammar enables additional features that help users:

• Spelling correction:

  
    What is the lentgh of Kennedy?
    = length
  

  Because we know from the grammar that a <ship-prop> is expected, the list of possible ship properties can be used as input to a spelling corrector algorithm to automatically correct the input.

• Sentence fragments:

  
    What is the length of Kennedy?
    
    speed
    = What is the speed of Kennedy?
  

  If the input can be parsed as a part of the previous parse tree, the rest of the input can be filled in.
