EVALUATING PRESENTATION OF PRODUCTS OFFERED BY A PUBLISHING USER BASED ON CONTENT ITEMS PROVIDED TO AN ONLINE SYSTEM BY OTHER USERS

摘要

A publishing user identifies a product offered by the user to an online system by providing multiple images of various products viewed at different angles to the online system. The online system applies an identification model to content items obtained from other users to identify one or more of the products in various content items. From a number of content items obtained from other users that include products offered by the publishing user, the online system compute trends. The trends may be for a specific product or products having one or more common attributes. The online system transmits information about the trends to the publishing user or to other users. The trends may also be used to rank recommendations for products to a specific user, where the trends from numbers of content items including products are weighted by the specific user's preferences.
