Understand

We propose a methodology that allows communication with Piping and Instrumentation Diagrams (P&IDs) using natural language.

In particular, we represent P&IDs through the DEXPI data model as labeled property graphs and integrate them with Large Language Models (LLMs).
The approach consists of three main parts: 1) P&IDs are cast into a graph representation from the DEXPI format using our pyDEXPI Python package.
2) A tool for generating P&ID knowledge graphs from pyDEXPI.
