MIT Tech Review wrote an article to review Loeto, Servedio, Strogatz, & Tria (2017): Dynamics on expanding spaces: modeling the emergence of novelties. The researchers found a mathematical way to identify novelty/innovation from the language. This is great, isn't it? Perhaps we can use this method to measure the degree of novelty of the articles on TCR, NLT, and EdLab blog.
