coreason-codex

The Terminology Server for Bio-Pharma AI

coreason-codex acts as the "Universal Translator" for the platform. It bridges the "Semantic Precision Gap" in Bio-Pharma AI by enforcing the use of Standardized Vocabularies (OMOP CDM).

Executive Summary

While Large Language Models are fluent, they can be imprecise. coreason-codex ensures that when an Agent reads "Heart Attack", it records it as ConceptID: 312327 (Data), enabling precise retrieval, graph grounding, and regulatory reporting.

It provides tools for Agents to lookup, validate, and translate medical concepts using a "Frozen Lake" pattern for GxP compliance.

For detailed requirements, see the Product Requirements Document.

Getting Started

Prerequisites

• Python 3.12+
• Poetry

Installation

1. Clone the repository:

   git clone https://github.com/CoReason-AI/coreason-codex.git
   cd coreason-codex
   

2. Install dependencies:

   poetry install
   

Usage

Here is a quick example of how to use coreason-codex to normalize text to a standard concept.

from pathlib import Path
from coreason_codex.loader import CodexLoader
from coreason_codex.normalizer import CodexNormalizer
from coreason_codex.embedders import SapBertEmbedder

# 1. Initialize Loader with path to your Codex Pack
# Ensure you have a valid Codex Pack at this location
pack_path = Path("./codex_pack_v1")
loader = CodexLoader(pack_path)
duckdb_conn, lancedb_conn = loader.load_codex()

# 2. Initialize Embedder and Normalizer
embedder = SapBertEmbedder() # Uses cambridgeltl/SapBERT-from-PubMedBERT-fulltext
normalizer = CodexNormalizer(embedder, duckdb_conn, lancedb_conn)

# 3. Normalize Text
matches = normalizer.normalize("Heart Attack")

for match in matches:
    print(f"Concept: {match.match_concept.concept_name} (ID: {match.match_concept.concept_id})")
    print(f"Score: {match.similarity_score}")
