Jina AI

Milvus mendukung model pemeringkat Jina AI melalui kelas JinaRerankFunction. Fungsionalitas ini memungkinkan Anda untuk menilai relevansi pasangan kueri-dokumen secara efektif.

Untuk menggunakan fitur ini, instal dependensi yang diperlukan:

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

Kemudian, instal JinaRerankFunction:

from pymilvus.model.reranker import JinaRerankFunction

jina_rf = JinaRerankFunction(
    model_name="jina-reranker-v2-base-multilingual", # Defaults to `jina-reranker-v2-base-multilingual`
    api_key=JINAAI_API_KEY
)

Parameter:

• model_name (string)

  Nama model pemeringkat Jina AI yang akan digunakan untuk pengodean. Jika Anda membiarkan parameter ini tidak ditentukan, jina-reranker-v2-base-multilingual akan digunakan. Untuk daftar model yang tersedia, lihat Jina AI Reranker.

• api_key (string)

  Kunci API untuk mengakses API Jina AI.

Kemudian, gunakan kode berikut untuk memberi peringkat ulang dokumen berdasarkan kueri:

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 = jina_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")
