In computer science, and probably other disciplines as well, it is common to end every paper with a "future research" section. I always wondered what is the utility of this section. In particular:
A. How common is it, that a question from a "future research" section is actually researched by the same research group?
B. How common is it, that a question from a "future research" section inspires future research by other research groups?
Both these questions can be studied quantitatively, even semi-automatically, by comparing the contents of "future research" sections to the titles and abstracts of papers published in a later date. Has such a research been done?
