  • Patent number: 11841905
    Abstract: An online concierge system generates an item graph connecting item nodes with attribute nodes of the items. Example attributes include a brand, a category, a department, or any other suitable information about the item. When the online concierge system receives a search query to identify one or more items from a customer, the online concierge system parses the search query into combinations of terms and identifies item nodes and attribute nodes related to the search query. The online concierge system identifies item nodes and attribute nodes that are likely to result in a conversion. Information about the identified nodes is presented to the customer. The customer may select an item node to purchase the item, or an attribute node to execute a new search query based on terms associated with the attribute node.

  • Publication number: 20230036666
    Abstract: An online concierge system offers items for sale and uses different units of measurements for items, allowing users to purchase numbers of an item, a weight of an item, or a packages of an item. To avoid confusing users with multiple options for specifying a quantity of an item, the online concierge system determines whether to present an interface for purchasing an item by a number of the item, by weight of the item, or a number of packages in the item from dynamic information about the item. For example, the online concierge system obtains historical pricing information an items and computes a par-weight price for the item from prior purchases of the item. The online concierge system uses the par-weight of the item to select an interface for a user when purchasing the item.

  • Publication number: 20220108333
    Abstract: An online concierge system suggests subsequent search queries based on previous search queries and whether the previous search queries resulted in conversions. The online concierge system trains a machine learning model using previous delivery orders and whether initial and subsequent search queries in the previous delivery orders resulted in conversions. When the online concierge system receives a search query to identify one or more items from a customer, the online concierge system parses the search query into combinations of terms and identifies items related to the search query. In response to the search query resulting in a conversion, the online concierge system retrieves a conversion graph and presents a suggested subsequent search query based on the conversion graph. In response to the search query not resulting in a conversion, the online concierge system retrieves a non-conversion graph and presents a suggested subsequent search query based on the non-conversion graph.

  • Patent number: 10768509
    Abstract: The present invention is an on-camera flashlight, comprising a lower light holder and a top light holder freely rotatably connected to the lower light holder. A flashlight light source is mounted on the top of the top light holder. The light emitting diode and the flashlight light source are mounted on the on-camera flashlight, combined for ease of use. Two functions-in-one lighting device saves space, avoids overloading the camera, and makes it portable. Because the two light sources are set in combination, the cooperation and sequence of the two light sources are easier to control. As the light emitting diode is mounted on the top light holder which may freely rotate with respect to the lower light holder, the light emitting diode may also freely rotate. It is also convenient to adjust the light direction. Above features all remarkably facilitate operation and versatility of the on-camera flashlight.
