SentenceTransformer based on intfloat/multilingual-e5-base

This is a sentence-transformers model finetuned from intfloat/multilingual-e5-base. It maps sentences & paragraphs to a 768-dimensional dense vector space and can be used for semantic textual similarity, semantic search, paraphrase mining, 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("malma0/e5-gesn")
# Run inference
sentences = [
    'query: покрытие водными растворами',
    'passage: Деревянные конструкции. Антисептирование водными растворами: покрытий по фермам. Ед. изм.: 100 м2. Нанесение готового состава на поверхность',
    'passage: Деревянные конструкции. Антисептирование водными растворами: стен. Ед. изм.: 100 м2. Нанесение готового состава на поверхность',
]
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, 0.5590, 0.3800],
#         [0.5590, 1.0000, 0.7719],
#         [0.3800, 0.7719, 1.0000]])
