Intertextual Classifier (Chirho)

RoBERTa-base fine-tuned for classifying biblical cross-reference connection types.

"For God so loved the world that he gave his only begotten Son, that whoever believes in him should not perish but have eternal life." - John 3:16

Model Description

Given two Bible passages that are cross-referenced, this model classifies the type of intertextual connection between them into one of 7 categories:

Training Details

• —Base model: roberta-base (125M params)
• —Training data: 19,164 balanced examples (Grok-labeled from TSK cross-references)
• —Class balancing: WeightedTrainer with inverse-frequency CrossEntropyLoss + majority class capping
• —Epochs: 8
• —Best epoch: 8 (by eval loss)

Metrics (v2 - Retrained Feb 2026)

Improvement over v1

Root cause of v1 weakness: 76% class imbalance (thematic_parallel dominated). Fixed with:

1. 1.Balanced dataset (cap majority class, keep all minority examples)
2. 2.WeightedTrainer with inverse-frequency class weights

Usage

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="LoveJesus/intertextual-classifier-chirho",
    top_k=None,
)

text = "[CLS] Genesis 3:15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel. [SEP] Galatians 4:4 But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law [SEP]"

result = classifier(text)
print(result)
# [{'label': 'prophetic_fulfillment', 'score': 0.95}, ...]

Part of Bible ML Pipeline

This model is part of the Intertextual Reference Network pipeline:

1. 1.Embedder (LoveJesus/intertextual-embedder-chirho): Finds similar passages
2. 2.Classifier (this model): Classifies the connection type
