Figure 4.
The image depicts a scatter plot with the X-axis labelled Relevance degree, Centrality, standardized, signed, ranging from negative to positive values, and the Y-axis labelled Developmental degree, Density, standardized, signed, also spanning from negative to positive values. Different themes are represented by points on the plot, including A I and machine learning, Sustainable development, Hospitality and travel sector, and Automation and tourism, with each theme displaying its respective coordinates, indicated by comma separation. The themes are categorised into quadrants labelled Niche themes in the top left, Motor themes in the top right, Emerging/declining themes in the bottom left, and Basic themes in the bottom right. The layout illustrates thematic relationships in terms of relevance degree and developmental degree.Thematic map with annotated centrality−density
