阿莱夫·阿尔法

阿莱夫·阿尔法的语义嵌入有两种可能的使用方式。如果您有结构不同的文本(例如文档和查询),您会希望使用不对称嵌入。相反,对于结构相似的文本,建议采用对称嵌入。

不对称嵌入

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)

对称嵌入

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)
