Cohere

Milvus soporta los modelos reranker Cohere a través de la clase CohereRerankFunction. Esta funcionalidad permite puntuar eficazmente la relevancia de los pares consulta-documento.

Para utilizar esta función, instale las dependencias necesarias:

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

A continuación, instancie la clase CohereRerankFunction:

from pymilvus.model.reranker import CohereRerankFunction

# Define the rerank function
cohere_rf = CohereRerankFunction(
    model_name="rerank-english-v3.0",  # Specify the model name. Defaults to `rerank-english-v2.0`.
    api_key=COHERE_API_KEY # Replace with your Cohere API key
)

Parámetros

  • model_name (cadena)

    El nombre del modelo que se va a utilizar. Puede especificar cualquiera de los nombres de modelo disponibles de Cohere reranker, por ejemplo, rerank-english-v3.0, rerank-multilingual-v3.0, etc. Si deja este parámetro sin especificar, se utilizará rerank-english-v2.0. Para obtener una lista de los modelos disponibles, consulte Rerank.

  • api_key (cadena)

    La clave API para acceder a la API de Cohere. Para obtener información sobre cómo crear una clave API, consulte Cohere dashboard.

A continuación, utilice el siguiente código para rerank documentos basados en la 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 = cohere_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")

La salida esperada es similar a la siguiente:
