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.embeddings import AlephAlphaAsymmetricSemanticEmbedding

API Reference:

• AlephAlphaAsymmetricSemanticEmbedding from langchain.embeddings

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

embeddings = AlephAlphaAsymmetricSemanticEmbedding()

doc_result = embeddings.embed_documents([document])

query_result = embeddings.embed_query(query)

Symmetric

from langchain.embeddings import AlephAlphaSymmetricSemanticEmbedding

API Reference:

• AlephAlphaSymmetricSemanticEmbedding from langchain.embeddings

text = "This is a test text"

embeddings = AlephAlphaSymmetricSemanticEmbedding()

doc_result = embeddings.embed_documents([text])

query_result = embeddings.embed_query(text)
