BagelDB (AI를 위한 오픈 Vector Database)는 AI 데이터를 위한 GitHub와 같습니다. 사용자가 vector 데이터셋을 생성하고, 공유하며, 관리할 수 있는 협업 플랫폼입니다. 독립 개발자를 위한 개인 프로젝트, 기업을 위한 내부 협업, 데이터 DAO를 위한 공개 기여를 지원할 수 있습니다.

text로부터 VectorStore 생성하기

from langchain_community.vectorstores import Bagel

texts = ["hello bagel", "hello langchain", "I love salad", "my car", "a dog"]
# create cluster and add texts
cluster = Bagel.from_texts(cluster_name="testing", texts=texts)

# similarity search
cluster.similarity_search("bagel", k=3)

[Document(page_content='hello bagel', metadata={}),
 Document(page_content='my car', metadata={}),
 Document(page_content='I love salad', metadata={})]

# the score is a distance metric, so lower is better
cluster.similarity_search_with_score("bagel", k=3)

[(Document(page_content='hello bagel', metadata={}), 0.27392977476119995),
 (Document(page_content='my car', metadata={}), 1.4783176183700562),

doc으로부터 VectorStore 생성하기

from langchain_community.document_loaders import TextLoader
from langchain_text_splitters import CharacterTextSplitter

loader = TextLoader("../../how_to/state_of_the_union.txt")
documents = loader.load()
text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
docs = text_splitter.split_documents(documents)[:10]

# create cluster with docs
cluster = Bagel.from_documents(cluster_name="testing_with_docs", documents=docs)

# similarity search
query = "What did the president say about Ketanji Brown Jackson"
docs = cluster.similarity_search(query)
print(docs[0].page_content[:102])

metadata로 cluster 생성하고 metadata를 사용하여 필터링하기

texts = ["hello bagel", "this is langchain"]
metadatas = [{"source": "notion"}, {"source": "google"}]

cluster = Bagel.from_texts(cluster_name="testing", texts=texts, metadatas=metadatas)
cluster.similarity_search_with_score("hello bagel", where={"source": "notion"})
