• Semantic Analysis: In this stage, the semantic analyser checks the meaningfulness of the text and extracts
                 logical meaning from it. This task is done by mapping syntactic structures and objects in the task domain. In the
                 example the meaning of the sentence is checked to make sure it actually makes sense. For example, it will reject
                 a sentence that contains “cruel kindness” in it.




                                             The agile deer over leaped the sluggish bear

                                                             WRONG



                                             The agile deer leaped over the sluggish bear


                                                              RIGHT



                 • Discourse Integration: In this stage, the meaning of the sentence is drawn according to the meanings of the
                 preceding and succeeding sentences.



                                      The agile deer leaped over the sluggish bear. Then it went
                                                           into the hedges.

                                                      Here "it" means "the deer"




                                      The agile deer leaped over it. Then it went into the hedges.

                                                         Here "it" is unknown



                 In the example, the meaningfulness of the preceding statement is dependent on the meaningfulness of the
                previous statement.
                 • Pragmatic Analysis: In this stage, deriving those aspects of language which require real world knowledge. The
                 actual meaning of the sentence is rechecked in this process.



                                                  Hang on, I will see you in a while.



                                               Means "Wait a moment, I will be back
                                                          to see you later"




                                                It does not mean that one needs to
                                                        hang on to something
