Users may now create a Knowledge Graph of up to 150 references from a reference result set. Clicking the Knowledge Graph button in a reference result set opens the graph in a new tab.


Note: If there are more than 150 references in a result set, only the first 150 (based on the currently applied filters and sort order) will be contained in the Knowledge Graph.

The Knowledge Graph consists of nodes and edges:

  • Nodes (Circles): Represent the references, organizations, and authors contained in the result set and the substances and concepts that are indexed in those references.
  • Edges (Lines): Represent the connections between the nodes.

On the left side of the Knowledge Graph is a drawer that can be opened and closed. When open, the drawer displays the Knowledge Graph filters. Knowledge Graph filters operate the same as filters for a reference result set but are limited to those references that are contained in the graph.

At the top of the Knowledge Graph, there is the key with color-coded information types. Toggling each type will display/hide it the graph.

Clicking the substance displays a pop-up with the structure image and CAS Registry Number; clicking the number opens the detail page for the substance.


Mousing over a reference displays its connections to the displayed information types.
