The technique can include: (1) accessing a plurality of emails, where each email is included in a respective folder of one or more folders, (2) establishing a set of n-grams based on the plurality of emails, (3) for each n-gram in the set of n-grams: calculating a respective normalized entropy for the n-gram, and calculating a respective indexing power for the n-gram based on its respective normalized entropy, (4) ranking the n-grams based on their respective indexing powers to establish a ranked list of n-grams, and (5) establishing, for each folder of the one or more folders, a respective set of high-value n-grams based on the ranked list of n-grams. In turn, the high-value n-grams can be compared against n-grams of a new email to identify a target folder into which the new email should be sorted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Techniques for automatically sorting emails into folders","description":"The embodiments set forth techniques for sorting emails within an email application.
