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
