Aleph Alpha
There are two possible ways to use Aleph Alpha's semantic embeddings. If you have texts with a dissimilar structure (e.g. a Document and a Query) you would want to use asymmetric embeddings. Conversely, for texts with comparable structures, symmetric embeddings are the suggested approach.
Asymmetric
from langchain_community.embeddingsimport 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)
Symmetric
from langchain_community.embeddingsimport 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)
