BGE-M3 Latin Intertextuality Embedding Model

This model is a fine-tuned version of BAAI/bge-m3 for generating embeddings of Latin texts to detect intertextual relationships.

The model is part of the Loci Similes benchmark setup (Schelb et al., 2026), evaluated on expert-verified Latin intertextual links. It is designed to work with the LociSimiles Python package API: https://julianschelb.github.io/locisimiles/api/.

Model Description

• Task: Sentence embedding for detecting intertextual links between classical Latin authors
• Model type: Sentence Transformer (Embedding Model)
• Base model: BAAI/bge-m3
• Negative sampling ratio: 1_pos_to_10_neg
• Fold uploaded: 0
• Language: Latin
• License: Apache 2.0

Usage

from sentence_transformers import SentenceTransformer

model = SentenceTransformer("julian-schelb/bge-m3-emb-lat-intertext-v1")
query_embedding = model.encode("Query: arma virumque cano")
candidate_embedding = model.encode("Candidate: arma virumque cano troiae qui primus ab oris")

If prompts are configured in the model, prefer:

• prompt_name="query" for query texts
• prompt_name="match" for candidate texts
