Jina AI

Milvus supporta i modelli di reranker di Jina AI attraverso la classe JinaRerankFunction. Questa funzionalità consente di assegnare un punteggio alla rilevanza delle coppie query-documento in modo efficace.

Per utilizzare questa funzione, installare le dipendenze necessarie:

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

Quindi, istanziare la classe 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
)

Parametri:

• model_name (stringa)

  Il nome del modello di Jina AI reranker da utilizzare per la codifica. Se si lascia questo parametro non specificato, verrà utilizzato jina-reranker-v2-base-multilingual. Per un elenco dei modelli disponibili, consultare Jina AI Rerankers.

• api_key (stringa)

  La chiave API per accedere all'API di Jina AI.

Quindi, utilizzare il codice seguente per eseguire il reranking dei documenti in base alla query:

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")

Il risultato atteso è simile al seguente:
