This is a sentence-transformers model finetuned from sentence-transformers/multi-qa-mpnet-base-dot-v1. 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.

python

from sentence_transformers import SentenceTransformer

# Download from the 🤗 Hub
model = SentenceTransformer("sentence_transformers_model_id")
# Run inference
sentences = [
    'Onde é mencionado oficialmente o NDE do curso de Ciência Da Computação, conforme a Portaria nº ?',
    '**3.4 Núcleo Docente Estruturante do Curso**<br><br>O NDE do curso de Ciência Da Computação, conforme designado na Portaria nº <br><br>Projeto Pedagógico do Curso de Ciência Da Computação,*Campus*Chapecó. <br><br>17 ',
    '**IDENTIFICAÇÃO INSTITUCIONAL**<br><br>A Universidade Federal da Fronteira Sul foi criada pela Lei Nº 12.029, de 15 de <br><br>35  setembro de 2009. Tem abrangência interestadual com sede na cidade catarinense de <br><br>Chapecó, três*campi*no Rio Grande do Sul – Cerro Largo, Erechim e Passo Fundo – e dois <br><br>*campi*no Paraná – Laranjeiras do Sul e Realeza. ',
]
embeddings = model.encode(sentences)
print(embeddings.shape)
# [3, 768]

# Get the similarity scores for the embeddings
similarities = model.similarity(embeddings, embeddings)
print(similarities.shape)
# [3, 3]
