AI Technical Summary

Technical Problem

Accessing and analyzing clinical trial data is hindered by complex data formats, data segmentation across large repositories, and inconsistent data standards, leading to inefficiencies in retrieval and analysis.

Method used

Utilizing generative artificial intelligence (GenAI) systems and knowledge graphs to transform natural language queries into structured representations, which are then mapped to database schemas to generate database queries, enabling efficient data retrieval and analysis.

Benefits of technology

Facilitates near real-time, ad-hoc delivery of analytical insights with reduced computational resources and bandwidth, allowing users to access and analyze clinical trial data without manual manipulation, and standardizing report generation across datasets.

Abstract

Methods and systems for retrieving data from at least one database based on a query input related to a clinical trial. A system processes a received query input related to a clinical trial using a pre-trained language model neural network. The neural network generates a structured representation of the query input. The system maps a first data field of the structured representation to a first column name and maps a second data field of the structured representation to a second column name. The system generates a database query based on (i) a database schema, (ii) the first column name, (iii) the second column name, (iv) data values associated with the first data field, and (v) data values associated with the second data field. The database query specifies an operation for joining data associated with the first column name with data associated with the second column name.
