opengovcorpus 0.1.4

A library for creating structured datasets and RAG embeddings from government websites

OpenGovCorpus

A Python library for creating structured datasets and RAG embeddings from government websites.

Installation

We recommend using UV for fast, reliable package installation:

uv pip install opengovcorpus

Or with pip:

pip install opengovcorpus

Configuration

Setting Up API Keys

Create a configuration file to store your API credentials:

Location: ~/.opengovcorpus/config.json

{
  "provider": "openai",
  "api_key": "sk-your-api-key-here"
}

The library supports multiple embedding providers:

• OpenAI: "provider": "openai"
• Gemini: "provider": "gemini"
• Hugging Face: "provider": "huggingface"

The library automatically reads this configuration file when generating embeddings.

Usage

Import the Library

import opengovcorpus as og

1. Create Dataset

Scrape a government website and create a structured knowledge graph with prompt-response pairs, automatically split into train/validation/test sets.

og.create_dataset(
    name="uk",                    # Name of the dataset folder
    url="https://data.gov.uk",       # Government website to scrape
    include_metadata=True,           # Include metadata for each prompt-response pair
    train_split=0.8,                 # 80% for training
    val_split=0.1,                   # 10% for validation
    test_split=0.1,                  # 10% for testing
    max_pages=10                     # Number of pages to scrape
)

Output Structure:

OpenGovCorpus-uk/
├── train.csv
├── valid.csv
└── test.csv

Each CSV contains structured prompt-response pairs suitable for fine-tuning or RAG applications.

2. Generate RAG Embeddings

Convert your dataset into vector embeddings for retrieval-augmented generation (RAG) applications.

og.create_rag_embeddings(
    model="openai/text-embedding-3-large",           # Embedding model
    vector_db="chroma",                              # Vector database (Chroma by default)
    config_path="~/.opengovcorpus/config.json"      # Optional: Path to config file (defaults to ~/.opengovcorpus/config.json)
)

Note: The config_path parameter is optional. If not specified, it automatically uses the config file created in the Configuration section above (~/.opengovcorpus/config.json).

Supported Models:

• OpenAI: openai/text-embedding-3-large, openai/text-embedding-3-small
• Gemini: gemini/text-embedding-004
• Hugging Face: hf/sentence-transformers/all-MiniLM-L6-v2, hf/BAAI/bge-large-en-v1.5

How it works:

1. Reads train.csv, valid.csv, and test.csv from your dataset
2. Converts prompts (and optionally responses) into vector embeddings
3. Stores embeddings in the specified vector database (Chroma local storage by default)
4. Enables efficient semantic search and retrieval for RAG applications

Complete Example

import opengovcorpus as og

# Step 1: Create dataset from government website
og.create_dataset(
    name="uk-data",
    url="https://data.gov.uk",
    include_metadata=True,
    train_split=0.8,
    val_split=0.1,
    test_split=0.1
)

# Step 2: Generate embeddings for RAG
og.create_rag_embeddings(
    model="openai/text-embedding-3-large",
    vector_db="chroma"
    # config_path is optional - uses ~/.opengovcorpus/config.json by default
)
