COMPARING ENTERED CONTENT OR TEXT TO TRIGGERS, TRIGGERS LINKED TO REPEATED CONTENT BLOCKS FOUND IN A MINIMUM NUMBER OF HISTORIC DOCUMENTS, CONTENT BLOCKS HAVING A MINIMUM SIZE DEFINED BY A USER

Automated presentation of repeated content is provided herein. Using historic documents, an index of repeatedly-used content blocks is created. As a user authors a current document, the authoring application is in communication with a trigger analyzer that receives edits and authoring commands from the user. The trigger analyzer compares the edits and authoring commands to the indexed content blocks, and creates previews of potential matches from the index of repeated content that are provided to the user. Depending on user preferences and application settings, these previews are presented to the user as selectable controls in a graphical user interface. If the user selects a preview, the content block associated with the preview is transmitted to the current document for insertion therein. The present disclosure improves the user experience, reduces the use of bandwidth, memory, and processing power to reuse content between documents.
