Code for calculating the ephemerality metrics that can be used to estimate how "ephemeral" discussion topics are based on their temporal dynamics, that is how persistent (or not) these discussions are through time. 2 versions of the metric are provided, ephemerality 2 and ephemerality 4 as described in https://arxiv.org/abs/2203.11261. The expected input is a temporal vector representing the discussion in question (e.g. the number of tweets per day) and, optionally, the output file name. The results are printed in the stdout and, if the file name was provided, saved to it in JSON format.
