Aleph Alpha

有两种使用 Aleph Alpha 语义嵌入的可能性。如果您有结构不同的文本（例如文档和查询），您会想要使用不对称嵌入。反之，对于结构相似的文本，建议使用对称嵌入。

非对称

from langchain_community.embeddings import AlephAlphaAsymmetricSemanticEmbedding

API Reference:AlephAlphaAsymmetricSemanticEmbedding

document = "This is a content of the document"
query = "What is the content of the document?"

embeddings = AlephAlphaAsymmetricSemanticEmbedding(normalize=True, compress_to_size=128)

doc_result = embeddings.embed_documents([document])

query_result = embeddings.embed_query(query)

对称性

from langchain_community.embeddings import AlephAlphaSymmetricSemanticEmbedding

API Reference:AlephAlphaSymmetricSemanticEmbedding

text = "This is a test text"

embeddings = AlephAlphaSymmetricSemanticEmbedding(normalize=True, compress_to_size=128)

doc_result = embeddings.embed_documents([text])

query_result = embeddings.embed_query(text)
