Voyage

O Milvus suporta o modelo de reranker Voyage através da classe VoyageRerankFunction. Esta funcionalidade permite-lhe classificar a relevância dos pares consulta-documento de forma eficaz.

Para utilizar esta funcionalidade, instale as dependências necessárias:

pip install --upgrade pymilvus
pip install "pymilvus[model]"

Em seguida, instancie a classe VoyageRerankFunction:

from pymilvus.model.reranker import VoyageRerankFunction

# Define the rerank function
voyage_rf = VoyageRerankFunction(
    model_name="rerank-lite-1",  # Specify the model name. Defaults to `rerank-lite-1`.
    api_key=VOYAGE_API_KEY # Replace with your Voyage API key
)

Parâmetros:

• model_name (string)

  O nome do modelo Voyage a ser usado para codificação. Se deixar este parâmetro não especificado, será utilizado rerank-lite-1. Para obter uma lista dos modelos disponíveis, consulte Rerankers.

• api_key (string)

  A chave da API para acessar a API do Voyage. Para obter informações sobre como criar uma chave de API, consulte Chave de API e cliente Python.

Em seguida, use o código a seguir para classificar documentos com base na consulta:

query = "What event in 1956 marked the official birth of artificial intelligence as a discipline?"

documents = [
    "In 1950, Alan Turing published his seminal paper, 'Computing Machinery and Intelligence,' proposing the Turing Test as a criterion of intelligence, a foundational concept in the philosophy and development of artificial intelligence.",
    "The Dartmouth Conference in 1956 is considered the birthplace of artificial intelligence as a field; here, John McCarthy and others coined the term 'artificial intelligence' and laid out its basic goals.",
    "In 1951, British mathematician and computer scientist Alan Turing also developed the first program designed to play chess, demonstrating an early example of AI in game strategy.",
    "The invention of the Logic Theorist by Allen Newell, Herbert A. Simon, and Cliff Shaw in 1955 marked the creation of the first true AI program, which was capable of solving logic problems, akin to proving mathematical theorems."
]

results = voyage_rf(
    query=query,
    documents=documents,
    top_k=3,
)

for result in results:
    print(f"Index: {result.index}")
    print(f"Score: {result.score:.6f}")
    print(f"Text: {result.text}\n")

O resultado esperado é semelhante ao seguinte:
