Usage

Direct Usage (Sentence Transformers)

First install the Sentence Transformers library:

pip install -U sentence-transformers

Then you can load this model and run inference.

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
queries = [
    'define reservedness',
]
documents = [
    'Definition of reservedness in the English dictionary The definition of reservedness in the dictionary is the quality or state of being cool or formal in manner or of being restrained, silent, or reticent. english words that begin like reservedness reserve tank',
    "Princeton's WordNet(0.00 / 0 votes)Rate this definition: 1  reserved(adj) set aside for the use of a particular person or party. 2  reserved(adj) marked by self-restraint and reticence.",

This is a syntactic definition, and a reserved word may have no meaning. A closely related and often conflated notion is a keyword, which is a word with special meaning in a particular context.

]
query_embeddings = model.encode_query(queries)
document_embeddings = model.encode_document(documents)
print(query_embeddings.shape, document_embeddings.shape)
# [1, 768] [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(query_embeddings, document_embeddings)
print(similarities)
# tensor([[0.5359, 0.4371, 0.3782]])
