Interpretation of co-ocurrence network

[IBranca]

Hello,
First of all, really thank you for such useful software and all the clarifications that may be found in the manual and forum.
I have read the explanations about the co-occurrence plot (that it uses igraph, references to the Fruchterman-Reingold algorithm, and other that you gently exposed here https://sourceforge.net/p/khc/discussion/222396/thread/2da0ff02/).
I have still some doubts about the plot of co-occurrence when you select a specific term.
How is that term taken into account for the betweenness and community plot?
Why are there some terms that have no edges to the term selected? and also some terms without any community colour (white)?
I am not sure about the explanation of how the communities are determined in reference to a specific term, and all these details.
Thank you so much in advance for any help or clarifying reference!

Hello,

How is that term taken into account for the betweenness and community plot?

Sorry, I don't understand your question clearly. Words are considered as "nodes" in networks. Then methods for analyzing networks are deployed. For the details of those methods, please see literatures that I referred in the article or the manual.

Why are there some terms that have no edges to the term selected?

I think you are talking about co-occurrences network that is made by "network" button in the "Word Association" window. As stated in manual, the degrees of association between words are calculated solely based on the documents that satisfy the search conditions of "Word Association" window. In other words, edges are calculated from partial data and relatively stronger edges in that partial data are drawn. So, it is possible that the selected words have no edges in the network.

and also some terms without any community colour (white)?

Those words were considered isolated or not forming a community with other words by the community detection method you chose.
