Cohere

Milvus unterstützt Cohere-Reranker-Modelle durch die Klasse CohereRerankFunction. Diese Funktionalität ermöglicht es Ihnen, die Relevanz von Abfrage-Dokumenten-Paaren effektiv zu bewerten.

Um diese Funktion zu nutzen, installieren Sie die notwendigen Abhängigkeiten:

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

Dann instanziieren Sie die Klasse 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
)

Parameter

• model_name (Zeichenkette)

  Der Name des zu verwendenden Modells. Sie können jeden der verfügbaren Cohere Reranker-Modellnamen angeben, z. B. rerank-english-v3.0, rerank-multilingual-v3.0, usw. Wenn Sie diesen Parameter nicht angeben, wird rerank-english-v2.0 verwendet. Eine Liste der verfügbaren Modelle finden Sie unter Rerank.

• api_key (Zeichenkette)

  Der API-Schlüssel für den Zugriff auf die Cohere-API. Informationen zum Erstellen eines API-Schlüssels finden Sie unter Cohere Dashboard.

Verwenden Sie dann den folgenden Code, um die Dokumente auf der Grundlage der Abfrage zu bewerten:

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")
