The first quadrant, characterized by high density and centrality, represents “motor themes” that are well-developed both internally and externally. The second quadrant is labeled as “highly developed-and-isolated themes” as it deals with niche themes. The third quadrant, with low density and centrality, is termed the “emerging-or-declining themes” quadrant. Themes in this quadrant are characterized by weak ties at both internal and external levels. Finally, the “basic-and-transversal themes” quadrant, with low density and high centrality, comprises themes that are weakly developed in terms of internal ties but have important external ties, characterized by high development potentiality.
