Unlike traditional graphs that show adjacency or connectivity relationships, Sankey diagrams visualize quantified transfers of resources, research attention, or intellectual influence using arrows whose width is proportional to the magnitude of the flow. This representation is compelling for analyzing temporal trajectories, interdisciplinary transfers, and redistributions of research focus over time.  \n8.1. Interpretation  \nProper interpretation of these maps requires understanding that the width of the connections encodes specific quantitative values. At the same time, the spatial arrangement reveals the structure of the system’s relationships.  \nFigure 8.1. Example of a Sankey diagram  \nReading a bibliometric Sankey diagram involves breaking it down into three main structural components: the nodes representing discrete categories (disciplinary fields, institutions, countries), the flows connecting these nodes indicating transfers or relationships, and the direction indicating the temporal or causal orientation of these transfers. The interpretation begins by identifying the dominant flows, those wider connections that represent the most intense relationships, to understand the main channels of intellectual exchange or institutional collaboration. Subsequently, the analysis shifts to secondary flows, which, although less intense, may reveal emerging connections or specialized niches with potential for future development. Finally, the identification of isolated nodes or those with few connections to areas disconnected from mainstream research, or to opportunities to establish new collaborations.  \nThe temporal dimension in Sankey maps adds analytical depth by allowing the tracking of diachronic changes in flow patterns. When the diagram represents successive periods, changes in the thickness of the connections between different temporal segments reveal dynamics of consolidation, diversification, or reorientation of lines of research.  \nThe progressive strengthening of specific flows indicates the emergence of new specialties orthe intensification of established collaborations. In contrast, the thinning or disappearance of  \nSankey diagrams: flows and relationships between concepts / Mapas de Sankey: flujos y relaciones entre conceptos  \nothers suggests the decline of paradigms or the breakdown of research alliances. This ability to visualize trajectories makes Sankey maps an exceptional tool for analyzing scientific mobility, the evolution of research interests, and the reconfiguration of disciplinary boundaries.  \nContextualized interpretation transcends immediate quantitative analysis by integrating explanatory factors that give meaning to the observed patterns. An intense flow between two disciplinary fields may reflect both fruitful integration of conceptual frameworks and mere instrumental appropriation of methodologies, without proper intellectual synthesis. The concentration of flows around specific nodes may indicate genuine intellectual leadership or scale effects derived from the size of research communities.  \nThe expert analyst distinguishes among these possibilities by triangulating with qualitative evidence and specialized domain knowledge, transforming the Sankey diagram from a descriptive representation into a diagnostic tool for understanding the dynamics of change in the scientific landscape.  \nThe specific bibliometric applications of Sankey maps ra","cbCaipObyTl2yYN2","https://ap.wps.com/l/cbCaipObyTl2yYN2","pdf",294474,"English","# 8.1.
