Do Schwartz Higher-Order Values Help Sentence-Level Human Value Detection? When Hard Gating Hurts
Víctor Yeste, Paolo Rosso (2026), arXiv:2602.00913

It is a multi-label classifier over the 19 refined Schwartz basic values, trained on the English, machine-translated portion of the ValueEval'24 / ValuesML corpus.

Inputs: a single sentence (news / political text, in English).
Outputs: a probability for each of the 19 Schwartz values.
Labels: we collapse “attained” and “constrained” into a single binary label per value (value is expressed vs. not expressed).

This is the text-only DeBERTa-base baseline used in the paper. In the experiments, it is also one of the members of the best-performing ensemble (Baseline + LIWC-22 + Previous-2-Sentences).

Intended use

Research on human value detection and moral language.
Baseline / starting point for work on:
- Schwartz value theory in NLP
- Moral/value-aware text analysis in news and political discourse
- Multi-label classification under class imbalance

The model was not trained or audited for safety-critical or high-stakes decision-making.

Labels

The 19 labels follow the refined Schwartz value continuum:

Self-direction: thought
Self-direction: action
Stimulation
Hedonism
Achievement
Power: dominance
Power: resources
Face
Security: personal
Security: societal
Tradition
Conformity: rules
Conformity: interpersonal
Humility
Benevolence: caring
Benevolence: dependability
Universalism: concern
Universalism: nature
Universalism: tolerance

How to use

1. Quick start: direct use with Transformers

Because this model uses a custom architecture (EnhancedDebertaForSequenceClassification with extra feature inputs), it is loaded via AutoModelForSequenceClassification(..., trust_remote_code=True) rather than the generic pipeline("text-classification"), which only supports a fixed list of built-in model classes.

python

import torch
from transformers import AutoTokenizer, AutoModelForSequenceClassification

model_id = "VictorYeste/human-value-detection-deberta-baseline"

tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForSequenceClassification.from_pretrained(
    model_id,
    trust_remote_code=True,  # important for custom model code
)

values = [
    "Self-direction: thought",
    "Self-direction: action",
    "Stimulation",
    "Hedonism",
    "Achievement",
    "Power: dominance",
    "Power: resources",
    "Face",
    "Security: personal",
    "Security: societal",
    "Tradition",
    "Conformity: rules",
    "Conformity: interpersonal",
    "Humility",
    "Benevolence: caring",
    "Benevolence: dependability",
    "Universalism: concern",
    "Universalism: nature",
    "Universalism: tolerance",
]

id2label = {i: label for i, label in enumerate(values)}

def predict_values(text, threshold=0.50):
    enc = tokenizer(text, return_tensors="pt", truncation=True)
    with torch.no_grad():
        outputs = model(**enc)

    logits = outputs.logits.squeeze(0)          # (19,)
    probs = torch.sigmoid(logits)               # tensor of shape (19,)
    probs = probs.cpu().numpy()

    active = probs >= threshold
    active_labels = [id2label[i] for i, is_on in enumerate(active) if is_on]

    return {
        "probs": {id2label[i]: float(p) for i, p in enumerate(probs)},
        "labels": active_labels,
    }

example = "We must do more to protect the environment and future generations."
print(predict_values(example))

This will return something like:

{
    'probs': {
        'Self-direction: thought': 0.004236925393342972,
        'Self-direction: action': 0.007529713679105043,
        'Stimulation': 0.014666699804365635,
        'Hedonism': 0.004158752970397472,
        'Achievement': 0.017073791474103928,
        'Power: dominance': 0.006939167156815529,
        'Power: resources': 0.0076741743832826614,
        'Face': 0.0034943644423037767,
        'Security: personal': 0.00695117749273777,

        'Conformity: rules': 0.0017643438186496496,
        'Conformity: interpersonal': 0.004064192529767752,
        'Humility': 0.0032048451248556376,
        'Benevolence: caring': 0.011124887503683567,
        'Benevolence: dependability': 0.017767170444130898,
        'Universalism: concern': 0.01814778335392475,
        'Universalism: nature': 0.9813610911369324,
        'Universalism: tolerance': 0.0025894937571138144
    },
    'labels': ['Universalism: nature']
}

Note: this is a multi-label model that returns all labels with scores in [0,1]. You still need to choose a threshold to decide what counts as “present”.

2. Multi-label usage with a custom threshold

For research use, you will often want to:

Apply a sigmoid over logits
Use a label-wise or global threshold (e.g., 0.3 instead of 0.5)

The predict_values function above already takes a threshold argument, so you can simply do:

predict_values(example, threshold=0.30)

and tune the threshold on your own validation set depending on your precision/recall preferences.

Training data

The model was trained on the English, machine-translated portion of the ValueEval’24 / ValuesML dataset:

Domain: news articles and political manifestos
Unit of analysis: individual sentences
Labels: 19 refined Schwartz values
Each value has attained and constrained annotations in the original data
For this model, these are collapsed into a single binary label per value
Presence variable in the paper ((z_s)) is defined as “any of the 19 labels is positive”, but this model directly predicts the 19 values.

Important: the original dataset is distributed under a restricted Data Usage Agreement. You must obtain the data separately from the ValueEval/ValuesML organisers (e.g. via Zenodo) and respect their license.

Training setup

Base model: microsoft/deberta-base
Task: 19-way multi-label classification
Objective: binary cross-entropy (BCEWithLogits) over the 19 labels
Max sequence length: 512 tokens
Optimizer: AdamW
Effective batch size: 16 (batch 4 × gradient accumulation 4)
Learning rate: 2e-5
Weight decay: 0.15
Epochs: up to 10 with early stopping on validation macro–F1
Hardware: single GPU with ≤ 8 GB VRAM

This is the text-only baseline configuration in the paper (no LIWC or context features).

Performance (paper reference)

On the English ValueEval’24 sentence-level splits used in the paper, this baseline DeBERTa model achieves:

Macro–F₁ (19 values, test): ~0.31 (with a tuned global threshold around 0.30)

The paper reports comparisons with:

Presence-gated hierarchies
Feature-augmented DeBERTa models (LIWC-22, prior-sentence context, topics)
Instruction-tuned LLM baselines (7–9B)
A small soft-voting ensemble of three DeBERTa-based models (including this baseline) obtains the best overall performance (macro–F₁ ≈ 0.33).

Limitations and bias

The model is trained on news and political texts; it may not generalise to:
- Social media
- Everyday conversations
- Other genres or languages
Values are annotated at the sentence level; many real-world value cues are only clear in broader context.
Rare values (e.g., Humility, Hedonism, Universalism: tolerance) have few positive examples and are harder to predict.
No systematic bias or fairness analysis has been conducted; the model should not be used for profiling individuals or making high-stakes decisions.

If you use this model, please:

Keep humans in the loop.
Treat outputs as noisy indicators, especially for rare labels.
