SentenceTransformer

This is a sentence-transformers model trained. 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.

Model Details

Model Description

  • Model Type: Sentence Transformer
  • Maximum Sequence Length: 8192 tokens
  • Output Dimensionality: 768 dimensions
  • Similarity Function: Cosine Similarity

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 = [

    Dictum est, id quod in nomine confuse significaretur, in definitione quae fit enumeratione partium, aperiri atque explicari. Quod fieri non potest, nisi per quarumdam partium nuncupationem; nihil enim dum explicatur oratione, totum simul dici potest. Quae cum ita sint, cumque omnis hujusmodi definitio quaedam sit partium distributio, quatuor his modis fieri potest. Aut enim substantiales partes explicantur, aut proprietatis partes dicuntur, aut quasi totius membra enumerantur, aut tanquam species dividuntur. Substantiales partes explicantur, cum ex genere ac differentiis definitio constituitur. Genus enim quod singulariter praedicatur, speciei totum est. Id genus sumptum in definitione, pars quaedam fit. Non enim solum speciem complet, nisi adjiciantur etiam differentiae, in quibus eadem ratio quae in genere est. Nam cum ipsae singulariter dictae totam speciem claudant, in definitione sumptae, partes speciei fiunt, quia non solum speciem quidem esse designant, sed etiam genus.
