EquiBERT — DEI Relation Extraction

Model ID: SallySims/equibert-relation-extraction

Extracts typed relations between DEI entities using entity markers. Input format: [E1] subject [/E1] ... [E2] object [/E2]

Relation Types (12)

Usage

text = "[E1] manager [/E1] excluded [E2] BIPOC employees [/E2] from the workshop."
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)
# relation = id2label[model(**inputs).logits.argmax(-1).item()]

Model Description

EquiBERT is a multi-task DEI (Diversity, Equity and Inclusion) transformer built on a dual-encoder backbone that fuses RoBERTa-base and DeBERTa-v3-base via a learned weighted sum (α parameter). The fused representation is fed into task-specific heads covering 17 distinct DEI analysis tasks.

Organisation: SallySims Framework: PyTorch + HuggingFace Transformers Backbone: RoBERTa-base + DeBERTa-v3-base (dual encoder, fused) Language: English Domain: Organisational DEI text — HR communications, policies, job descriptions, performance reviews, leadership statements, reports

Training Data

Trained on synthetic DEI organisational text generated by the EquiBERT synthetic data pipeline, covering 20 DEI categories across HR, policy, leadership, and workforce analytics domains. For production use, fine-tune on real labelled DEI data.

Limitations

• —Trained on synthetic data — predictions should be validated before use in real HR or policy decisions.
• —English-only.
• —Not a substitute for qualified DEI practitioners or legal advice.
• —May reflect biases present in the training corpus.
