Underneath a picture and life summary of an ancestor in Story View are zoomed-out pictures of documents, instead of discrete fields of structured text. Next to the images, Ancestry can plug in blurbs generated from information in the document. Those draw from a system that engineers drew up in house. Once Ancestry has found all the records associated with a person, it selects specific facts to pull out of them based on Ancestry editors’ rules, and assembles them into full sentences. Once the document-based blurbs are displayed in the browser, customers can edit and save them before sharing.
