Their study also investigated the performance of humans on such a task and found that the machine learning algorithm was more consistent although it was outperformed by one of the expert human analysts.
examples of technologies which could be applied include semantic role labeling, (Swier and Stevenson, 2004) deep syntactic parsing, (Lucic and Blake, 2011), and LDA for detecting levels of metaphor (Heintz et al., 2013), in order to obtain a clearer picture of the stylistic structure of such documents.
