Notes on blockmodeling

TL;DR: Providing an in-depth examination of core text mining and link detection algorithms and operations, this text examines advanced pre-processing techniques, knowledge representation considerations, and visualization approaches.

TL;DR: Pajek (spider, in Slovene) is a program package, for Windows (32 bit), for analysis and visualization of large networks (having thousands of vertices) that is freely available, for noncommercial use, at its home page.

TL;DR: In this article, the authors present an in-depth comparative review of the methods presented so far for clustering directed networks along with the relevant necessary methodological background and also related applications.

TL;DR: An in-depth comparative review of the methods presented so far for clustering directed networks along with the relevant necessary methodological background and also related applications is offered.

TL;DR: The algebraic definitions presented here are motivated by the search for an adequate formalization of the concepts of social roles as regularities in social network patterns and represent significant homomorphic reductions of social networks which are possible using these defimtions to capture the role structure of a network.

TL;DR: In this paper, a criterion function for a local optimization partitioning procedure for signed digraphs is proposed, which yields those partitions with the smallest number of errors, a measure of the imbalance in the graph and an identification of those links inconsistent with both generalized and structural balance.

TL;DR: A new criterion function is presented that operationalizes the concept of regular equivalence and provides a measure of the departure of any structure from an exact regular partition that is applied to partitions where the algorithm minimizes the criterion function.

TL;DR: It is argued that once committed to a specific form of equivalence, a network analyst must be committed also to an explicit method of assessing the extent to which a blockmodel is consistent with the selected form of interchangeability.
