System

A system comprising:

• circuitry configured to:
• receive input information from a user terminal;
• acquire history information and preference information from a storage device and numeralize the history information and the preference information as feature quantities to generate user feature information;
• generate a first prompt sentence embedding the user feature information and input the first prompt sentence to a generative artificial intelligence model to generate structured candidate information representing ranked candidate destinations;
• acquire weather prediction information from an external weather information service and generate a second prompt sentence encoding the weather prediction information and a travel-purpose type;
• input the second prompt sentence to the generative artificial intelligence model to obtain portable article candidate information and post-process the portable article candidate information by performing duplicate-item removal, classification assignment, and display-format conversion to generate portable article information;
• and
• analyze at least one of text information and audio information using an emotion analysis engine to generate an emotion analysis result and dynamically adjust content of at least one of the first prompt sentence and the second prompt sentence based on the emotion analysis result.

A method performed by circuitry, the method comprising:

• receiving input information from a user terminal;
• acquiring history information and preference information from a storage device based on user identification information and numeralizing the history information and the preference information as feature quantities to generate user feature information;
• generating a first prompt sentence embedding the user feature information together with the input information and inputting the first prompt sentence to a generative artificial intelligence model to generate structured candidate information representing ranked candidate destinations;
• acquiring weather prediction information from an external weather information service and constructing context information comprising the weather prediction information, a selected destination, and a travel-purpose type;
• generating a second prompt sentence encoding the context information and inputting the second prompt sentence to the generative artificial intelligence model to obtain portable article candidate information;
• post-processing the portable article candidate information by performing duplicate-item removal, classification assignment, and display-format conversion to generate portable article information;
• and
• analyzing at least one of text information and audio information using an emotion analysis engine to generate an emotion analysis result and dynamically adjusting content of at least one of the first prompt sentence and the second prompt sentence based on the emotion analysis result.
