Each full-text query activates a new window that shows the search term together with its strongest associations within the search results (the shown associations therefore consider the sample, selected time interval and global sentiment filter):

• The color of data points encodes the sentiment of a term.
• Clicking on any of the new terms extends the graph with up to eight child nodes.
• The ‘+’ symbol in the upper right corner triggers this process for each of the displayed nodes, thereby showing the next hierarchical level in its entirety.
• ‘Edges’ refers to the number of connections to be considered when adding new elements to the graph. The default value is 4, which can be increased up to a maximum of 8 connections.
• Clicking on a parent node again deletes its child nodes from the display, allowing the analyst to filter out unwanted sub-trees.
• Clicking on the central term resets the diagram.

The resulting semantic network, which can be enlarged to full screen size, is a powerful tool to investigate how different stakeholder groups perceive a topic over time, and what negative and positive associations they have with this topic.
