I am writing the list for ethics guidance on reusing a publicly-shared Twitter dataset I found <https://github.com/DrMassie/Covid_tweets/> for academic research. The data contains "four variables are in each dataset: created_at (i.e., the date of the tweet), username (i.e., the handle of the user), text (i.e,. *the tweet itself*), and location (i.e., information on user profile that the user put as his/her location)." In particular, has the data has been shared properly? As far as I can tell, "properly" would mean "in accordance with the Twitter ToS". After reading the current Twitter ToS <https://twitter.com/en/tos> and developer agreements <https://developer.twitter.com/en/developer-terms/agreement> I am still unsure. (I would ask our copyright librarian - but she is on sabbatical until January!) The associated paper - which is quite interesting - is: Fogarty, B., Massie, K., and Svistova, J. (2024). Unmasking Twitter discourse: An infodemiology study of Covid-19 mitigation practices. *The Atlantic Journal of Communication*. http://doi.org/10.1080/15456870.2023.2220855 They say "*The data and files that we have generated are freely available for public and academic use as long as our original work is sited *(sic) *as the source*." The dataset is described as "Keyword "coronavirus" tweets from March to May 2020 before covid or covid19 became popular". Thoughts? Thanks! -Jodi http://jodischneider.com/jodi.html
