Jina AI

Milvus 通过JinaRerankFunction类支持Jina AI ranker 模型。通过该功能，您可以对查询-文档对的相关性进行有效评分。

要使用该功能，请安装必要的依赖项：

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

然后，实例化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
)

参数：

• model_name (字符串）

  用于编码的 Jina AI reranker 模型名称。如果不指定此参数，则将使用jina-reranker-v2-base-multilingual 。有关可用模型的列表，请参阅Jina AI Rerankers。

• api_key （字符串）

  访问 Jina AI API 的 API 密钥。

然后，使用以下代码根据查询结果对文档进行重排：

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")
