SentenceTransformer based on intfloat/multilingual-e5-base

This is a sentence-transformers model finetuned from intfloat/multilingual-e5-base on the train dataset. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, text classification, clustering, and more.

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
sentences = [
    'Прием осуществляется только по результатам дополнительных вступительных испытаний (ДВИ профильной, творческой и/или профессиональной направленности), проводимых МГУ в 2022 году.',
    'Как осуществляется прием по специальной квоте для детей военнослужащих и сотрудников, погибших или получивших увечье, в МГУ в 2022 году?',
    'На каком основании осуществляется отнесение поступающих к числу детей военнослужащих и сотрудников в пределах специальной квоты?',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities)
# tensor([[1.0000, 0.8577, 0.7622],
#         [0.8577, 1.0000, 0.8551],
#         [0.7622, 0.8551, 1.0000]])
