System

A system comprising:

• circuitry configured to
• receive, via a packet-switched network, an entity identifier from a terminal device,
• generate a first structured input sequence for a generative neural network model based on the entity identifier,
• execute a data acquisition process to retrieve structured record data from a plurality of external data endpoints and normalize the structured record data into attribute-categorized data records,
• generate a second structured input sequence from the attribute-categorized data records for the generative neural network model to produce a comparative analysis output,
• transmit the comparative analysis output to the terminal device for rendering on a display,
• receive a selection signal indicating a selected data record,
• generate a third structured input sequence instructing the generative neural network model to produce transaction execution parameters associated with the selected data record, and
• transmit, via the packet-switched network, the transaction execution parameters to the terminal device.

A method performed by a system comprising circuitry, the method comprising:

• receiving, via a packet-switched network, an input data set from a terminal device, the input data set comprising an entity identifier specifying a target for which structured record data is to be retrieved;
• generating, based on the entity identifier, a first structured input sequence for a generative neural network model, the first structured input sequence instructing the generative neural network model to produce retrieval parameters for obtaining the structured record data from a plurality of external data endpoints;
• executing a data acquisition process that transmits query requests to the plurality of external data endpoints based on the retrieval parameters, receives response data from the plurality of external data endpoints, and normalizes the response data into attribute-categorized data records stored in a data repository;
• generating, from attribute fields of the attribute-categorized data records, a second structured input sequence for the generative neural network model, the second structured input sequence instructing the generative neural network model to produce a comparative analysis output evaluating the attribute-categorized data records;
• and
• transmitting, via the packet-switched network, the comparative analysis output together with the attribute-categorized data records to the terminal device for rendering on a display of the terminal device.
