Methods and systems for providing purchase recommendations to users

A computer system for determining vehicle recommendations based on user interaction, the computer system comprising:

• a memory storing instructions;
• and
• one or more processors configured to execute the instructions to perform operations including:
• initiating a chatbot session enabling a user of a user device to communicate with a chatbot via a messaging interface displayed on the user device, the chatbot being executed by the computer system;
• determining a set of vehicle characteristics represented in a candidate set of vehicles;
• performing one or more iterations of a preference identification process including:
• determining a respective percentage of the candidate set possessed by each vehicle characteristic in the set of vehicle characteristics;
• selecting, from the set of vehicle characteristics, a vehicle characteristic based on proximity of the respective percentage to 50%;
• transmitting, to the user device during the chatbot session, an inquiry for a user preference regarding the selected vehicle characteristic, so that the inquiry is presented to the user via the messaging interface;
• receiving, from the user device during the chatbot session, a response indicating the user preference regarding the selected vehicle characteristic, so that the response is received from the user via the messaging interface;
• and
• based on the response, reducing a quantity of vehicles in the candidate set and/or adjusting the set of vehicle characteristics;
• and
• presenting, to the user device, a vehicle listing interface including a recommendation of one or more vehicles from the reduced candidate set and one or more interactive search filters set by the computer system in accordance with at least one user preference received in at least one of the one or more iterations of the preference identification process.

A computer system for implementing an artificial-intelligence interactive agent for determining vehicle recommendations based on user interaction, the computer system comprising:

• a memory storing instructions and a database of vehicles;
• and
• one or more processors configured to execute the instructions to perform operations including:
• initiating a chatbot session enabling a user of a user device to communicate with a chatbot via a messaging interface displayed on the user device, the chatbot being executed by the computer system;
• transmitting, to a user device during the chatbot session, a request to indicate a type of vehicle desired by a user of the user device;
• receiving, from the user device during the chatbot session, an indication of the type of vehicle desired by the user;
• determining a candidate set of vehicles, selected from vehicles described in the database, based on the type of vehicle desired;
• performing a plurality of iterations of a preference identification process including:
• determining a respective percentage of the candidate set possessed by each vehicle characteristic in a set of vehicle characteristics,
• selecting, from the set of vehicle characteristics, a vehicle characteristic for which the respective percentage is closest to 50%,
• transmitting, to the user device during the chatbot session, an inquiry for a user preference regarding the selected vehicle characteristic, so that the inquiry is presented to the user via the messaging interface,
• receiving, from the user device during the chatbot session, a response to the inquiry indicating the user preference regarding the selected vehicle characteristic, so that the response is received from the user via the messaging interface, and
• based on the response to the inquiry, reducing a quantity of vehicles in the candidate set and/or adjusting the set of vehicle characteristics,
• wherein the respective selected characteristic is different for each of the plurality of iterations of the preference identification process, and at least one of the plurality of iterations reduces the quantity of vehicles in the candidate set;
• and
• transmitting, to the user device, a web page including a vehicle listing interface, the vehicle listing interface including a list of one or more vehicles from the reduced candidate set and one or more interactive search filters set by the computer system in accordance with at least one user preference received in at least one of the one or more iterations of the preference identification process.
