During a network mapping analysis of Keywords and authors coocurrences of a batch of references from the WOS, by specifying a weight on the sum of coocurrences, what exactly corresponds to the number indicated in the weight column of the gefx export?Thanks in advance
It should be, for a given term, the sum over every other term of the number of douments in which the two co-occur.
I’m asking the author of the script to confirm.
Hi Beatrice, thank you Ale for your first answer,
more precisely, nodes are assigned a weight parameter which is equal to the total number of times node has co-occurred with other nodes of the map by default.
If you set the weight parameter to frequency, then the weight of nodes (and their size in the final map) will simply scale with the total number of occurrences of nodes.
Note that, cooccurrences and occurrences count are “mostly” proportional.
