Mapping the complexity of political ideology using emergent networks: the Chilean case

Abstract

We propose a method to characterize political ideology using network theory. Our analysis is based on the 2015–2016 Chilean constituent process, where self-convened meetings were held throughout the country to discuss which Values, Rights, Duties, and Institutions should be included in the new constitution. Using this unique dataset, co-occurrence networks were constructed by considering the concepts selected in dif‐ ferent meetings. The nodes are the concepts, and a link between two nodes represents the association between them. Political ideology is thus analyzed as an emergent net‐ work, and we can identify the main ideological communities in Chile and describe their characteristics. Beyond the local results, the proposed methodology enables represent‐ ing the diversity of a community’s political orientations in a realistic ecological context.
