Communities in social networks are often defined as groups of densely connected actors. However, members of the same dense group are not equal but may differ largely in their social position or in the role they play. Furthermore, the same positions can be found across the borders of dense communities so that networks contain a significant group structure which does not coincide with the structure of dense groups. This papers gives a survey over formalizations of network-positions with a special emphasis on the use of algebraic notions.http://www.bibsonomy.org/bibtex/269f7d2fe711ef85ad70e5de28e7b005e/stummestumme2007-09-19T14:15:47+02:00network world small networks sna <span style="color:#555555;">Luca <a href="http://www.bibsonomy.org/author/Dall&#039;Asta">Dall'Asta</a> and Andrea <a href="http://www.bibsonomy.org/author/Baronchelli">Baronchelli</a> and Alain <a href="http://www.bibsonomy.org/author/Barrat">Barrat</a> and Vittorio <a href="http://www.bibsonomy.org/author/Loreto">Loreto</a> </span><em>Europhysics Letters</em>(<em>2006</em>)Wed Sep 19 14:15:47 CEST 2007Europhysics Letters969Agreement dynamics on small-world networks732006network world small networks sna Introduction to Special Issue on "Social Network and Discrete Structure Analysis" of the Journal "Social Networks"http://www.bibsonomy.org/bibtex/254623418afefedc61bb05f69a8245506/stummestumme2006-11-24T16:47:13+01:00sna social lattices networks analysis fca <span style="color:#555555;">D. <a href="http://www.bibsonomy.org/author/White">White</a> and V. <a href="http://www.bibsonomy.org/author/Duquenne">Duquenne</a> </span><em>Social Networks</em><em>18(3):169--172</em><em>#aug#1996. </em>Fri Nov 24 16:47:13 CET 2006Social Network and Discrete Structure AnalysisSocial Networks#aug#3169--172Introduction181996sna social lattices networks analysis fca http://www.bibsonomy.org/bibtex/20d6b995d6befb04a68aa8638d69887d8/stummestumme2006-10-25T11:30:09+02:00segmentation network networks sna social measures <span style="color:#555555;">T.

However, beside consistency checking, current ontology engineering tools provide only basic functionalities for analyzing ontologies. Since ontologies can be considered as (labeled, directed) graphs, graph analysis techniques are a suitable answer for this need. Graph analysis has been performed by sociologists for over 60 years, and resulted in the vivid research area of Social Network Analysis (SNA). While social network structures in general currently receive high attention in the Semantic Web community, there are only very few SNA applications up to now, and virtually none for analyzing the structure of ontologies. We illustrate in this paper the benefits of applying SNA to ontologies and the Semantic Web, and discuss which research topics arise on the edge between the two areas. In particular, we discuss how different notions of centrality describe the core content and structure of an ontology. From the rather simple notion of degree centrality over betweenness centrality to the more complex eigenvector centrality based on Hermitian matrices, we illustrate the insights these measures provide on two ontologies, which are different in purpose, scope, and size.
