Someone kindly gave me a copy of Social Networks and the Semantic Web the Ph.D. thesis of Péter Mika at the Free University of Amsterdam. The thesis contains precisely what the title suggests: the application of Semantic Web technology to Social Network Analysis. I guess, the most visible application of Péter's research is Flink which takes co-authored papers as the main source of the social network.
Chapter 3 contains an excellent overview of SNA in general, covering several issues I have thought about (what is a network, what are the boundaries and so forth).
Page 58 is the best page in the thesis. It contains Figure 4.1, an illustration of the structure of a weblog (links, quotes, comments and such). Although the illustration, a screenshot, is anonymous I recognised it immediately. It is the Thinking and berries in Umea post of Lilia. Further down the page it gets even better:
The early work of Efimova and Anjewierden also stands out in that they were among the first to study blogs from a communication perspective. [Understanding weblog communities through digital traces: a framework, a tool and an example, International Workshop on Community Informatics (COMINF 2006), Montpellier, France.]
A nice social touch in a nice thesis.
