Jina AI 랭커 (Jina AI)

Milvus는 JinaRerankFunction 클래스를 통해 Jina AI reranker 모델을 지원해요. 이 기능으로 쿼리-문서 쌍의 관련성을 효과적으로 점수화할 수 있어요.

본문

이 기능을 사용하려면 필요한 의존성을 먼저 설치해요:

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

그다음 JinaRerankFunction을 인스턴스화해요:

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
)

파라미터:

• model_name (string) 인코딩에 사용할 Jina AI reranker 모델의 이름이에요. 이 파라미터를 지정하지 않으면 jina-reranker-v2-base-multilingual이 사용돼요. 사용 가능한 모델 목록은 Jina AI Rerankers를 참고하세요.

• api_key (string) Jina AI API에 접근하기 위한 API 키예요.

그다음 아래 코드로 쿼리를 기준으로 문서를 리랭킹해요:

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")
