Cite-Attribution 0.2.0

A library for constructing citable prompts and attributing contributions of context sources in RAG systems

Attribution

A Python library for attributing contributions of context sources in Retrieval-Augmented Generation (RAG) systems.

Installation

pip install Cite-Attribution

Features

• LLM-Based Citation: Explicit citations during LLM generation using DSPy
• Embedding-Based Citation: Post-processing attribution via semantic similarity
• Profit Share Calculation: Weighted citation aggregation for fair attribution

Quick Start

Embedding-Based Attribution

from attribution import run_embedding_attribution_pipeline

# Your LLM response (without citations)
response = "The capital of France is Paris. It is known for the Eiffel Tower."

# Context sources with their indices
context = {
    1: "Paris is the capital and largest city of France.",
    2: "The Eiffel Tower is a famous landmark in Paris.",
}

# Map node indices to server/source names
node_map = {
    1: "wikipedia",
    2: "travel_guide",
}

# Run the pipeline
result = run_embedding_attribution_pipeline(
    response_text=response,
    context=context,
    node_map=node_map,
)

print(result["cited_response"])  # Response with <cite:X>...</cite> tags
print(result["stats"])           # Citation statistics per server
print(result["profit_share"])    # Normalized contribution scores

LLM-Based Attribution

from attribution import run_llm_attribution_pipeline

# Pre-generated response with citation tags
cited_response = "<cite:[1]>Paris is the capital of France.</cite> <cite:[2]>The Eiffel Tower is iconic.</cite>"

# Map node indices to server names
node_map = {
    1: "wikipedia",
    2: "travel_guide",
}

result = run_llm_attribution_pipeline(
    generated_response=cited_response,
    node_map=node_map,
)

print(result["profit_share"])

Constructing Citation Prompts

from attribution import construct_citation_prompt

prompt = construct_citation_prompt(
    query="What is the capital of France?",
    context={
        1: "Paris is the capital of France.",
        2: "France is a country in Europe.",
    }
)

API Reference

Core Functions

• aggregate_server_citations(llm_response, node_to_server_map): Parse citations and count per server
