The last share tells how far the topic passes through few hands: in the field it ranges from 12% to 39%. 17% means that the topic is widespread, with no recognisable centre. Signatures are counted, not papers: an article with four authors on the topic weighs four times, because the question is how much of the work passes through few people.
By papers on the topic. The last column still shows specialisation, to tell apart those who work on it a lot in absolute terms from those who work on it above all.
Not those who published the most on it, but those who devote the largest share of their output to it compared with the field average. Above 1 there is specialisation; the tick marks parity. Researchers with fewer than three papers on the topic are excluded.
