1,025,168 articles
We can use interlinks between articles to apply SNA techniques
Community detection: sets of highly inter-connected nodes
InfoMap algorithm, very fast
It produces 1,314 communities, 342 have more than 10 articles
they can be evaluated by hand, 23 were assigned to S&T
Performs additional checks over links to tune articles assignment
119,686 articles on S&T
