The knowledge panel is displayed. For example, the document system 108 can update the display or service of the document to the user device 106 to cause the knowledge panel to be displayed contemporaneously with the document. If, for example, the document system 108 serves the documents editor, the document system 108 may update the document editor to include the knowledge panel. If an application on the user device 106 displays the document, the document system 108 can serve the content to be displayed in a knowledge panel, data representing or renderable into a knowledge panel, or other appropriate data to the application for rendering to the user.

An update to the document is detected (410). For example, the user may make changes to an existing portion of the document, or may add new content to the document. In such a case, the document system 108 may repeat the process 400, possibly identifying a new logical entity in the updated portion of the document.

A particular number, type, and order of steps have been described. However, other numbers, types, and orders of steps may be used. For example, instead of requesting the knowledge panel from an external service, the document system 108 may generate the knowledge panel itself. As another example, the document may be a static document that the user cannot or does not update.
