I tried several times to make an Epic Epoch (to visualize the first 5 most used keywords in each article for each year, from 2010 to 2021), but it doesn’t work, I think it’s a data organization problem?!
- Write a title that summarizes the specific problem
- Introduce the problem before you post your question
- Help others reproduce the problem: corpus format, variable(s) used, parameters…
Thank you Lionel,
I downloaded my data set from Scopus (102 document results) csv file.
Start Script ==>> Data Parsing ==>> Epic Epoch (error)

how many years do you have in your dataset?
2010 to 2021 (12 years).
The best way to take benefit of Scopus data, required to export a RIS file. RIS is a standardized format to store bibliographical data. In that case, just use the RIS (Scopus) option during the parsing step in CorText Manager.
Otherwize, when exporting a csv from Scopus, and using the robust csv option for the parsing step, make sure to define the Time Field option. Otherwise Scripts that supposed to perform temporal analysis (as Epic Epoc) won’t work.
I hope it helps
