A "People Graph" is NASA's People Analytics Team's proposed solution for identifying subject matter experts, determining who should collaborate on which projects, helping employees upskill effectively, and more. By seamlessly deploying Memgraph on their private AWS network and leveraging S3 storage and EC2 compute environments, they have built an analytics infrastructure that supports the advanced data and AI pipelines powering this project. In this session, they will showcase how they have used Large Language Models (LLMs) to extract insights from unstructured data and developed a "People Graph" that enables graph-based queries for data analysis.

Secure, programmatic data ingestion into Memgraph from AWS S3 buckets.

Building a skills knowledge graph using LLM-extracted data and querying it for workforce insights.

Future plans, including interfacing with the graph via natural language querying.

Designed for developers, data engineers, and AI practitioners, this session will provide a real-world perspective on deploying graph databases in a cloud environment. Join us as we explore NASA’s architecture, challenges, and future aspirations in building AI-driven knowledge graphs for workforce intelligence.

David Meza currently serves as the Branch Chief, People Analytics and Head of Analytics for the NASA’s Office of Human Capital. He previously served as Chief Knowledge Architect at NASA Johnson Space Center (JSC). During his tenure at NASA, he has worked in all aspects of the Information Technology field developing and deploying several IT systems in use at JSC. His desire to improve IT processes and systems lead him to earn a Master’s certificates in Project Management and Six Sigma in addition to becoming a NASA certified Lean Six Sigma Master Black Belt. Mr. Meza is conducting research in People Analytics, Automatic Classification algorithms, entity tagging, topic modeling, data driven visualization and text to graph pipelines. He holds a Master’s in Engineering Management from the University of Houston Clear Lake.
