  • Patent number: 11954613
    Abstract: A method, apparatus and computer program product for establishing a logical connection between an indirect utterance and a transaction is described. An indirect utterance is received from a user as an input to a conversational system. The indirect utterance is parsed to a first logical form. A first set of predicates and terms is mapped from the first logical form to a first subgraph in a knowledge graph. A second set of predicates and terms is mapped from a second logical form belonging to a transaction to a second subgraph of the knowledge graph. A best path in the knowledge graph between the first subgraph and the second subgraph is searched for while transforming the first logical form using the node and edge labels along the best path to generate an intermediate logical form. A system action is performed for a transaction if a graph structure of the intermediate logical form matches the graph structure of the logical form of the transaction above a threshold.

    Abstract: Techniques for generating shopping routes through shopping environments are provided. A plurality of identified shopping list items are used to generate a shopping list for a user where the shopping list items are based on items the user needs. The shopping list is updated using a processed inventory image which identifies inventory items located in an inventory of the user. Items the user currently has are reduced or removed from the shopping list. When the shopping list is complete, a shopping route through a shopping environment is generated for the shopping list using a crowd-sourced or community updated map to provide an efficient route to the shopping list items in the shopping environment.
