Aleph Alpha
有兩種可能的方法可以使用 Aleph Alpha 的語義嵌入。如果您有結構不同的文本（例如，文檔和查詢），您會想使用非對稱嵌入。 相反，對於具有可比較結構的文本，建議使用對稱嵌入。
非對稱 (Asymmetric)
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)
對稱 (Symmetric)
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)
