***** To join INSNA, visit http://www.insna.org ***** I wanted to make sure I'm not missing any important bodies of work in the area that my work is concerned with: I am interested in building and analyzing accurate models of the real-world social network from copious amounts of electronic communication data (mostly email at this point, with plans to expand to instant messaging and/or phone data). What I have found is that given a network of relationships between people, the tools of SNA are well formed and mature for analyzing that network, and I am happy with the state of the art. What I have had more trouble finding is help in more accurately *characterizing each relationship*. I have seen models that refer to, for example, the "strength" of a relationship, but I have real trouble deciphering what that even *means*: do people in a strong relationship "like each other"? Do they trust each other? Will they do favors for each other? Or does it just mean that they are "familiar" with each other? And, are these directional quantities, or unidirectional qualities? Is it really the case that both people in a relationship like each other the same amount, or shouldn't this be a directional notion? It seems obvious that relationships are far too complex to be characterized by a single scalar. Is there research out there that has tried to address characterizing relationships more accurately and in more dimensions: 1) at all, and/or 2) from electronic communication data? I'm not even sure if this is research that would live in the SNA community so much as other fields like psychiatry or sociology; otoh, one thing I have learned about the SNA community is that it crosses many, many more traditional departments.
