The programmed computer automatically identifies groups of words that match the interest documents. The matching word groups are ranked by a weight that is assigned based on how infrequently a word group matches a reference corpus and how frequently the word group matches one or more interest document(s), in comparison to other word groups. A set of word groups are automatically identified based on ranking, and displayed to a user to select documents from a corpus. Selected documents are displayed to the user, e.g. with one or more group of words used in selecting the documents."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Finding relevant documents","description":"A programmed computer receives one or more documents that contain text that is relevant to a user (“interest documents”).
