We propose a method for creating co-word networks starting from keyphrases automatically extracted from the full text of scientific papers.
We release the following resources, available at this link https://github.com/dhfbk/Keyphrase_Co-Occurrence_Networks :
an R script to convert the output of KD in a list of undirected edges that can be imported in Gephi;
two folders containing the newtorks in Sigma.js generated from the abstracts of AIUCD 2015 and AIUCD 2018: to visualize and search in the networks, open the index.html files with FIREFOX.
