Pondering Bibliographic Coupling and Co-citation Analyses in the Context of Company Directorships by Tony Hirst.
From the post:
Over the last month or so, I’ve made a start reading through Mark Newman’s Networks: An Introduction, trying (though I’m not sure how successfully!) to bring an element of discipline to my otherwise osmotically acquired understanding of the techniques employed by various network analysis tools.
One distinction that made a lot of sense to me came from the domain of bibliometrics, specifically between the notions of bibliographic coupling and co-citation.
Co-citation
The idea of co-citation will be familiar to many – when one article cites a set of other articles, those other articles are “co-cited” by the first. When the same articles are co-cited by lots of other articles, we may have reason to believe that they are somehow related in a meaningful way.
(…)
Bibliographic coupling
Bibliographic coupling is actually an earlier notion, describing the extent to which two works are related by virtue of them both referencing the same other work.
Interesting musings about applying well known views of bibliographic graphs to graphs composed of company directorships.
Tony’s suggestion of watching for patterns in directors moving together between companies is a good one but I would broaden the net a bit.
Why not track school, club, religious affiliations, etc.? All of those form networks as well.
