The purpose of this file is to outline the procedure of extracting feature set 3.
First those sentences containing Negations were detected, extracted and exported (2.3.1 Negation Detection)
This subset served as an input for the Stanford Grammatical Parser. The Parser was used to create grammatical dependency tuplets (2.3.2 Negation Grammatical Dependency Analysis)
Using the dependency tuplets, those words being related to a Negation could be detected. Those words were tagged as “_NOT" (2.3.3 Negation Tagging)
In order to tag the remaining words, a subset of non-tagged words was created and used as an input for POS Tagging. Finally the text elements were remerged and the final feature set was created.
