Automate Semantic Vectorization of Medical Procedures for Enhanced Search

This workflow transforms medical procedures from the USS table into vector embeddings using Google Gemini, enabling efficient semantic search in a PostgreSQL database with pgVector.

n8n

The workflow automates the process of importing medical procedures from the USS table, preprocessing the text, and generating semantic vector embeddings using Google Gemini. These vectors are stored in a PostgreSQL database with the pgVector extension, facilitating advanced semantic search capabilities. This approach improves the precision of search results by focusing on the meaning of queries rather than exact keyword matches.
