Syntactic parsing is typically one of the first steps in a text mining pipeline.
different analysis show other problematic characteristics, including inconsistent use of nouns and partial words (Tateisi & Tsujii, 2004), higher perplexity measures (Elhadad, 2006), greater lexical density, plus increased number of relative clauses and prepositional phrases (Ge-moets, 2004), all of which correlate with diminished comprehension and higher text difficulty.
