There are several advantages to combining syntactic and semantic processing:

• Removal of Ambiguity: It is better to eliminate an incorrect parsing before it is generated, rather than generating all possible interpretations and then removing bad ones.
  • Computer time is saved.

  • Eliminating one bad partial interpretation eliminates many bad total interpretations.

• Reference: It is often advantageous to relate the sentence being parsed to the model that is being constructed during the parsing process. ``John holds the pole at one end [ of the pole].''

• Psychological Plausibility: People can deal with partial and even ungrammatical language.
