Two-mode networks are usually analyzed in one of two ways. With the “direct” approach using methods tailored for bipartite graphs, or with the “conversion” approach, which includes all methods that project the two-mode network onto each mode separately.

In this talk, Schoch focuses on one-mode projections where one mode serves as the primary mode and the second mode only as a proxy for relations among actors in the primary mode. Drawing parallels to item response theory, he argues that projected (and dichotomized) ties are conceptually different than traditional ties, which therefore restricts the applicability and interpretability of standard network analytic tools in such cases. Schoch will introduce a set of alternative methods to analyze one-mode projections and exemplify these with several empirical examples.
