Measuring informativity
The rise of compounds as informationally dense structures in 20th-century Scientific English
By applying data-driven methods based on information theory, this study adds to previous work on the
development of the scientific register by measuring the informativity of alternative phrasal structures shown to be involved
in change in language use in 20th-century Scientific English. The analysis based on data-driven periodization shows compounds
to be distinctive grammatical structures from the 1920s onwards in Proceedings A of the Royal Society of
London. Compounds not only increase in frequency, but also show higher informativity than their less dense
prepositional counterparts. Results also show that the lower the informativity of particular items, the more alternative, more
informationally dense options might be favoured (e.g., of-phrases vs. compounds) – striving for
communicative efficiency thus being one force shaping the scientific register.
