System and method for enhancing data fields in structured data files of property listings

A system for enhancing data fields in exchangeable structured data files of property listings, the system comprising a server in operable communication with a property management system across a wide area network, the server comprising a processor executing computer program code instruction controllers comprising:

• a data extraction and parsing controller configured to:
• receive a structured data file for a property listing from the property management system, the structured data file comprising populated data fields and free text;
• and
• identify incomplete data fields;
• a data enhancement controller comprising:
• a natural language processing sub-controller;
• and
• a large language model sub-controller, wherein the data enhancement controller is configured to:
• query the large language model sub-controller with a query generated by the natural language processing sub-controller according to a missing data field and contextual data obtained from the free text;
• update the missing data field in the structured data file with a response received from the natural language processing sub-controller to generate an enhanced structured data file;
• and
• a data pass-back controller configured to transmit the enhanced structured data file to the property management system.
