The chart presents percentage share of articles from 2004 to 2019 and total for four categories, synthesis, value in use, value proposition, and unclear. Each year is shown as a stacked bar summing to 100 per cent. Early years are dominated by unclear, with 100 per cent in 2004 and 50 per cent in 2005. Over time, synthesis increases steadily and becomes the largest share in later years. Value in use and value proposition fluctuate at moderate levels. A table below lists exact percentage values for all categories across each year and total.Shares of articles on different levels of analytical comprehensiveness
