Use Cluster Visualization if you want to discover the contents of your search field by topics.
The cluster visualization allows you to discover the contents of your search field by topics. We currently use the category property to cluster the documents. These are based on the IPTC Media Topics standard.
The cluster visualization is made up of bubbles representing topical clusters. As a general rule, the bigger the cluster is, the more Signals are within. The number of Signals within a bubble is printed on it.
⚠️ Note that a single Signal can belong to many categories. This is why adding up the counts of Signals on all bubbles will likely produce a higher number than the total number of Signals in the selection (which is printed at the top of the list of Signals). Some Signals are counted multiple times across the bubbles.
Zooming into Bubbles
The categorization we are currently using is hierarchical. This means that there are few high-level categories that have sub-categories which in turn can have further sub-categories.
When clicking on a bubble you will zoom into the bubble and can now see more detail about the bubble's children, like information about the documents within.
The label of the current bubble will be displayed at the top of the visualization with an "X" next to it that allows you to zoom out again.
⚠️ Be aware that some Signals belong only to a parent category and do not belong to any category lower in the hierarchy.
On any hierarchical level, you can select categories to filter the other visualizations and the list of Signals by. Simply hover over a bubble and tick the checkbox that appears. This will select the category and all its descendants. Your selection will be visible in the selection panel above the visualization.
