ボヤージュ

MilvusはVoyageRerankFunction クラスを通してVoyageリランカーモデルをサポートしています。この機能により、クエリとドキュメントのペアの関連性を効果的にスコアリングすることができます。

この機能を使用するには、必要な依存関係をインストールしてください:

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

そして、VoyageRerankFunction をインスタンス化します:

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
)

パラメータを指定します:

  • model_name (文字列)

    エンコードに使用する Voyage モデルの名前。このパラメータを指定しない場合、rerank-lite-1 が使用されます。利用可能なモデルのリストについては、Rerankersを参照してください。

  • api_key (文字列)

    Voyage APIにアクセスするためのAPIキー。APIキーの作成方法については、APIキーとPythonクライアントを参照してください。

次に、以下のコードを使用して、クエリに基づいてドキュメントをランク付けします:

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")

期待される出力は以下のようになる:
