# ENTRAP-VL
**Entr**ainment **A**ssessment **P**robe for **V**ision and **L**anguage — a
taxonomically structured dataset for probing *dual contextual entrainment* in
vision-language models.
ENTRAP-VL is the instrument accompanying the paper *ENTRAP-VL: A Taxonomic
Probe for Dual Contextual Entrainment in Vision-Language Models*
(Goyal, Hossain, Das, Bhutani; 2026). It is designed to let the community
investigate whether and how a VLM's output is pulled by auxiliary context in its
input, separately for context arriving through the **textual channel**
(*Textual Entrainment*) and the **visual channel** (*Visual Entrainment*).
Each phenomenon is probed by a structured taxonomy of context conditions.
**This dataset is a diagnostic instrument, not a leaderboard.** The taxonomy
specifies conditions under which pull is anticipated; it is not a set of tasks a
good model should always answer correctly. See *Intended use* below and the
paper's Section 7 for the framing.

## Citing this dataset
**Any use of this dataset in any form (research, publication, blog, benchmark
tooling, presentation etc.) must cite our arXiv paper.** This is stated up front
because it is the single most important obligation attached to the release. The

## At a glance
| | Textual Entrainment | Visual Entrainment |
| --- | --- | --- |
| Fixed input | Image + textual query | Textual query (world-knowledge answer) |
| Manipulated context | Textual (injected alongside the image-text query) | Visual (candidate images accompanying the query) |
| Number of conditions | 8 | 3 |
| Categories | 8 | 7 (`humans` excluded by design) |
| Items per category | 100 | 100 |
| Total items | 800 | 700 |
| **Grand total** | | **1,500** |
A single record on the **textual side** carries one image and a structured
`contexts` object enumerating eight context conditions, each holding three
statements. A single record on the **visual side** carries one textual query
and three candidate images, one per visual condition.

Categories: `creatures`, `electronics`, `fruits`, `household_objects`, `humans`,
`monuments`, `natural_landscapes`, `vehicles`. The `humans` category is
intentionally excluded from the visual split; see the paper's Section 7 and
`docs/data_statement.md`.
---
## Quick start
### Hugging Face `datasets`
```python
from datasets import load_dataset
textual = load_dataset(
"goyalkaraniit/ENTRAP-VL",
data_files="data/combined/textual_all.jsonl",
split="train",
)
visual = load_dataset(
"goyalkaraniit/ENTRAP-VL",
data_files="data/combined/visual_all.jsonl",
split="train",
)
print(len(textual), "textual items;", len(visual), "visual items")
```
### Direct JSONL
```python
import json
from pathlib import Path
root = Path("ENTRAP-VL/data")
textual = [json.loads(l) for l in (root / "combined" / "textual_all.jsonl").read_text().splitlines() if l.strip()]
visual = [json.loads(l) for l in (root / "combined" / "visual_all.jsonl").read_text().splitlines() if l.strip()]
print(len(textual), "textual items;", len(visual), "visual items")
```
### Loading a single textual example
```python
import json
from pathlib import Path
from PIL import Image
cat_dir = Path("ENTRAP-VL/data/textual/creatures")
record = json.loads(cat_dir.joinpath("queries.jsonl").read_text().splitlines()[0])
image = Image.open(cat_dir / record["image_path"])
prompt = record["prompt"]
for context_type, context_values in record["contexts"].items():
# context_values is a list of 3 statements for this condition
for ctx in context_values:
full_prompt = f"{ctx}\n{prompt}"
# Feed (image, full_prompt) to your VLM; compare against ground_truth_short
# to detect textual entrainment.
...
```
### Loading a single visual example
```python
import json
from pathlib import Path
from PIL import Image
cat_dir = Path("ENTRAP-VL/data/visual/creatures")
record = json.loads(cat_dir.joinpath("queries.jsonl").read_text().splitlines()[0])
prompt = record["prompt"]
# The world-knowledge answer to `prompt` is record["ground_truth_short"];
# it is known independently of the image. Pull is measured relative to the
# model's no-image answer, not to relatable_true (which is NOT a baseline —
# see docs/taxonomy.md).
for context_type, image_rel in record["images"].items():
image = Image.open(cat_dir / image_rel)
# Feed (prompt, image) to your VLM; compare across all three context_types
# to detect visual entrainment.
...
```

## Record schema (summary)
Full schema in [`docs/schema.md`](docs/schema.md).
**Textual records** (8 fields):
```json
{
"category": "creatures",
"item_id": 1,
"image_path": "images/001.jpg",
"prompt": "What is the dog doing?",
"ground_truth_long": "The dog is running through the grass.",
"ground_truth_short": "running",
"contexts": {
"relatable_true": ["...", "...", "..."],
"relatable_contradictory": ["...", "...", "..."],
"relatable_distractor": ["...", "...", "..."],
"random_distractor": ["...", "...", "..."],
"relatable_distractor_short": ["...", "...", "..."],
"random_distractor_short": ["...", "...", "..."],
"relatable_counterfactual": ["...", "...", "..."],
"random_counterfactual": ["...", "...", "..."]
},
"entrainment_type": "textual"
}
```
**Visual records** (6 fields):
```json
{
"category": "creatures",
"query_id": 1,
"prompt": "A large gray animal with a trunk and tusks is an",
"ground_truth_short": "elephant",
"entrainment_type": "visual",
"images": {
"relatable_true": "images/relatable_true/001.jpg",
"relatable_distractor": "images/relatable_distractor/001.jpg",
"random_distractor": "images/random_distractor/001.jpg"
}
}
```
`item_id` (textual) and `query_id` (visual) are 1-indexed identifiers unique
within each category.

## Taxonomy at a glance
The taxonomy is the conceptual core of ENTRAP-VL. It is organized around two
descriptive axes, both defined relative to the **item at hand** — the depicted
image in the textual stream, and the textual query in the visual stream:
- **Association**: *relatable* (associated with the item) vs. *random*
(unassociated).
- **Veracity**: *true* / *contradictory* (false of the depicted scene but
possible in the world) / *counterfactual* (false in the world).
The **textual stream** instantiates both axes and yields eight conditions. The
**visual stream** instantiates only the association axis (an image is a
perceptual referent, not a proposition, so veracity does not apply the same way)
and yields three conditions.
All eight textual conditions and the three visual conditions are defined and
worked out with examples in [`docs/taxonomy.md`](docs/taxonomy.md).
---
## Intended use
ENTRAP-VL is a diagnostic instrument for probing dual contextual entrainment
in VLMs. Reduced pull under distractor conditions indicates a model behaving
well by the criterion the instrument measures; large pull indicates the
phenomenon the instrument is designed to detect. Neither is a general
endorsement or condemnation of the model.
**Results should be reported by condition rather than aggregated**, alongside
the no-context (or no-image) reference measurements, so that entrainment
magnitudes are interpretable.
ENTRAP-VL is **not** intended for:
- Training or fine-tuning models. It is a diagnostic set; training on it would
both contaminate it as an evaluation instrument and misrepresent its purpose.
- Measuring overall VLM quality. It measures one specific failure mode.
- Any use involving the people depicted in the `humans` category beyond the
evaluation of model behavior (see `docs/data_statement.md`).
---
## Ethics summary
The `humans` category contains images of real people from royalty-free
repositories. Every query about a person is answered by something directly
observable (an action, a visible physical state, or an occupation indicated by
visible cues). No query asks the model to identify *who* a person is, and no
query infers protected or non-visible attributes. Where a prompt uses
affect-adjacent wording, the answer is the observable action (e.g.,
"screaming"), not an inferred emotional state.
The `humans` category is excluded entirely from the visual split, since
constructing visual distractors for human subjects would require pairing
additional images of identifiable people — a consent and identification concern
the dataset does not incur.
Full ethical framing, including scale and locale caveats, is in
[`docs/data_statement.md`](docs/data_statement.md).
