reranker-ModernBERT-base-gooaq-bce

ModernBERT-base trained on GooAQ

This is a Cross Encoder model finetuned from answerdotai/ModernBERT-base using the sentence-transformers library. It computes scores for pairs of texts, which can be used for text reranking and semantic search.

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 CrossEncoder

# Download from the 🤗 Hub
model = CrossEncoder("Oysiyl/reranker-ModernBERT-base-gooaq-bce")
# Get scores for pairs of texts
pairs = [
    ['what do you do with a degree in criminal justice?', "['Police Patrol Officer. Job Description. ... ', 'Criminal Investigators & Special Agents. Job Description. ... ', 'Private Detective or Investigator. ... ', 'First-Line Police Supervisor. ... ', 'Correctional Officer. ... ', 'Probation and Parole Officers. ... ', 'Postsecondary Criminal Justice & Law Enforcement Teachers.']"],

    ['what do you do with a degree in criminal justice?', "A high school diploma is required to work as a detective. In some cases a bachelor's degree in criminal justice or law enforcement may be needed. Experience in law enforcement is usually required, but the amount varies by employer."],

    ['what do you do with a degree in criminal justice?', "Crime Scene Investigator Education and Training Although a high school diploma or equivalent is a minimum requirement for some positions, many police departments and law enforcement agencies prefer a minimum of an associate's (two-year) or a bachelor's (four-year) degree in criminal justice or a natural science."],
]
scores = model.predict(pairs)
print(scores.shape)
# (5,)

# Or rank different texts based on similarity to a single text
ranks = model.rank(
