Cosine similarity utility

relevanceai.utils.distances.cosine_similarity.get_cosine_similarity_scores(self, documents: List[Dict[str, Any]], anchor_document: Dict[str, Any], vector_field: str) → List[float]#

Compare scores based on cosine similarity

Parameters

  • other_documents – List of documents (Python Dictionaries)

  • anchor_document – Document to compare all the other documents with.

  • vector_field – The field in the documents to compare

Example

>>> documents = [{...}]
>>> ViClient.get_cosine_similarity_scores(documents[1:10], documents[0])
