Figure 1
A line graph showing syntactical complexity variability in the first, middle, and last parts of documents from 2002 to 2012. The horizontal axis represents the years from 2002 to 2012, and the vertical axis represents the Flesch formula adapted values ranging from 40 to 54. The graph includes three data lines: First (blue), Middle (black), and Last (orange). Each line also has a corresponding period mean line: First part period mean (blue dashed), Middle part period mean (black dotted), and Last part period mean (orange dashed). The First part line shows fluctuations with peaks around 2005 and 2010. The Middle part line generally trends upwards with a dip around 2009. The Last part line shows a steady increase over the years. The period mean lines increase in every part from the first to the second period. The highest increase is in the Middle part and the lowest in the First part.Syntactical complexity variability: first, middle and last part of the documents (2002–2012)
