Jina AI
Milvus 透過JinaRerankFunction類別支援 JinaAI ranker 模型。此功能可讓您有效地為查詢與文件對的相關性進行評分。
要使用此功能,請安裝必要的相依性:
pip install --upgrade pymilvus
pip install "pymilvus[model]"
然後,實體化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
)
參數:
model_name
(字串)要用做編碼的 Jina AI reranker 模型名稱。如果未指定此參數,則會使用
jina-reranker-v2-base-multilingual
。如需可用模型的清單,請參閱Jina AI Rerankers。api_key
(字串)存取 Jina AI API 的 API 金鑰。
然後,使用下列程式碼根據查詢對文件進行 rerank:
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")
