Aleph Alpha

有兩種可能的方式可以使用 Aleph Alpha 的語義嵌入。如果您有結構不同的文本（例如，文件和查詢），您會想要使用非對稱嵌入。相反地，對於結構相似的文本，建議使用對稱嵌入。

非對稱

from langchain_community.embeddings import 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)

from langchain_community.embeddings import 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)
