  • Publication number: 20240086984
    Abstract: An online concierge system generates a graph connecting items with attributes of the items and other items. Hence, the graph includes nodes corresponding to attributes and nodes corresponding to items, with an item connected to attributes of the item in the graph. 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 compares different combinations of terms to the graph to determine connections between different combinations of terms in the graph. Based on measures of connectedness between combinations of terms and connections in the graph, items are identified from one or more combinations of terms. Information about the identified items is presented to the customer.

  • Patent number: 11314746
    Abstract: Systems and methods for continuous processing of unstructured data streams are provided. Information may be stored in memory regarding a query, including associated search results and statistics derived at an identified time. After the identified time, unstructured data may be received from a plurality of streams over a communication network. A full-text search may be conducted on the received unstructured data based on the query to yield one or more matches. The stored statistics associated with the query may be retrieved from memory and updated based on the search results of the unstructured data received at the subsequent time. The updated statistics may then be stored in memory for retrieval at a subsequent time.

  • Patent number: 11195222
    Abstract: In an online concierge system, a customer adds items to an online shopping cart. The online concierge system determines key ingredients from the items in the online shopping cart by mapping the items to generic items and removing non-ingredient items and staple items. The online concierge system retrieves recipes including at least one of the key ingredients. The online concierge system determines complementary ingredients based on the other ingredients in the recipes and calculates co-occurrence scores for the complementary ingredients. Using the co-occurrence scores, the online concierge system ranks the complementary ingredients and sends for display a subset of the complementary ingredients as recommended items.
