In this paper we discuss the use of Correspondence Analysis, in the
Greenacre’s doubling perspective, to analyze and graphically represent ordinal valued
two-mode networks. We discuss how this approach: i) takes into account the nature
of relational data and the asymmetry of the entities in two-mode networks; ii) permits
to directly analyze valued relational data, avoiding transformations; iii) deals with the
nature of the ratings and their bipolar character; iv) improves results interpretation.
