Publication number: 20230368276Abstract: Disclosed are systems, methods, and non-transitory computer-readable media for message timing optimization. A message timing optimization system determines optimized times to transmit messages to users based on historical transaction data. For example, the message timing optimization system may determine an optimal time to transmit a recommendation message to a user to perform a subsequent, such as repurchasing an item, refreshing a password, and the like. The message timing optimization system uses historical transaction data describing previous transactions performed by the user and/or other users to determine probability values indicating the likelihood that a user will perform a subsequent action at various time periods after the user performed an initial transaction.Type: ApplicationFiled: July 26, 2023Publication date: November 16, 2023Inventor: Alpha Kamchiu Luk

Publication number: 20230245035Abstract: A system for distributing items is provided. Requests from first users for items available from second users are received. The first users are associated with different shipping addresses. Clusters are identified from the requests. The clusters have items with similar characteristics and are requested by different first users. The clusters are then matched to individuals of the second users. First instructions for the individuals are generated that indicate a single shipment having items purchased by the first users are to be sent to a processor. Second instructions are generated for the processor. The second instructions include sorting instructions to sort the items from shipments received from the individuals. The second instructions include address instructions to determine shipping addresses for the first users. The second instructions include packaging instructions for packaging the sorted items according to the shipping addresses such that a single package is sent to individual first users.Type: ApplicationFiled: February 3, 2022Publication date: August 3, 2023Inventor: Alpha Kamchiu Luk

Patent number: 11507970Abstract: A system may receive information representing a first item and an item price of the first item from a first user device operated by a buyer. The first item may be available for sale by a merchant of a brick-and-mortar store. A plurality of sellers may be identified, the plurality of sellers may list a second item as being available for sale at the calculated reduced item price in an item listing for the second item. Moreover, the second item may be similar to the first item. A reduced item price may be calculated based on the item price of the first item received from the user device, the reduced item price representing a price lower than the item price of the first item. The item listing for the second item available for sale may be presented to the first user device operated by the buyer.Type: GrantFiled: October 12, 2021Date of Patent: November 22, 2022Assignee: EBAY INC.Inventor: Alpha Kamchiu Luk

Publication number: 20220114608Abstract: Automatic generation of individual item listings from a bulk listing is described. Bulk listing data associated with a bulk listing is obtained from a storage device associated with a listing system. The bulk listing data is processed to extract individual item information for individual items of the bulk listing. A plurality of individual item listings for the individual items of the bulk listing are automatically generated by populating the individual item listings with the respective individual item information extracted from the bulk listing data. In one or more implementations, relisting predictions for the individual items of the bulk listing are automatically generated and displayed in a graphical user interface.Type: ApplicationFiled: October 13, 2020Publication date: April 14, 2022Applicant: eBay Inc.Inventors: Saravanakumar Ganesan, Jing Zhao, Anindita Banerjee, Somashish Gupta, Alpha Kamchiu Luk
