OntoGPT

OntoGPT

Introduction

OntoGPT is a Python package for extracting structured information from text with large language models (LLMs), instruction prompts, and ontology-based grounding.

For more details, please see the full documentation.

Quick Start

OntoGPT runs on the command line, though there's also a minimal web app interface (see Web Application section below).

1. Ensure you have Python 3.9 or greater installed.

2. Install with pip:

   pip install ontogpt
   

3. Set your OpenAI API key:

   runoak set-apikey -e openai <your openai api key>
   

4. See the list of all OntoGPT commands:

   ontogpt --help
   

5. Try a simple example of information extraction:

   echo "One treatment for high blood pressure is carvedilol." > example.txt
   ontogpt extract -i example.txt -t drug
   

   OntoGPT will retrieve the necessary ontologies and output results to the command line. Your output will provide all extracted objects under the heading extracted_object.

Web Application

There is a bare bones web application for running OntoGPT and viewing results.

First, install the required dependencies with pip by running the following command:

pip install ontogpt[web]

Then run this command to start the web application:

web-ontogpt

NOTE: We do not recommend hosting this webapp publicly without authentication.

Evaluations

OntoGPT's functions have been evaluated on test data. Please see the full documentation for details on these evaluations and how to reproduce them.
