# ESNLIR — test split

The full test split of **ESNLIR**, a Spanish multi-genre NLI dataset with a *reasoning* (causal)
label: **80,213 sentence pairs**, label-balanced by construction.

This is the exact test split used to evaluate GPT-4o, GPT-4o-Mini, Qwen2.5-7B-Instruct and
Llama-3.1-8B-Instruct in **An Analysis of the Performance of Large Language Models in Spanish NLI
Datasets with Causal Relationships** (IBERAMIA 2026, to appear); code in
[`Pacolas/NLI-via-LLM`](https://github.com/Pacolas/NLI-via-LLM). The data itself comes from ESNLIR,
a separate contribution with its own code and paper. Part of the
[**ESNLIR-LLM**](https://huggingface.co/collections/Flaglab/esnlir-llm-6a74a6b9ce149918f48ebba5) collection.

## Format

Despite the `.json` extension, the file is **JSON Lines** — one object per line, no enclosing
brackets.

```json
{"sentence_1": "...", "sentence_2": "...", "connector": "por eso",
 "connector_type": "reasoning", "extraction_strategy": "linking_phrase", "distance": 1.0,
 "sentence_1_paragraph": 46, "sentence_1_position": 25,
 "sentence_2_paragraph": 46, "sentence_2_position": 26,
 "id": "esnews__spanish_pd_news__365259", "dataset": "esnews__spanish_pd_news",
 "genre": "news", "domain": "spanish_public_domain_news"}
```

The gold label is **`connector_type`**, derived from the discourse connector linking the two
sentences — it is *not* human-validated. For the human-validated subset see
[`Flaglab/esnlir-human-validated`](https://huggingface.co/datasets/Flaglab/esnlir-human-validated).

## Label distribution

| label | n |
|---|---|
| `entailment` | 20,054 |
| `contrasting` | 20,054 |
| `reasoning` | 20,053 |
| `neutral` | 20,052 |

## Genre distribution

| genre | n |
|---|---|
| `theses` | 28,348 |
| `books` | 17,540 |
| `comments` | 11,137 |
| `news` | 10,248 |
| `articles` | 6,568 |
| `legal` | 5,628 |
| `talks` | 548 |
| `clinical` | 196 |

## Usage

```python
from huggingface_hub import hf_hub_download
import json

p = hf_hub_download("Flaglab/esnlir-test", "test.json", repo_type="dataset")
rows = [json.loads(l) for l in open(p) if l.strip()]
```

## Reported results on this split

From the IBERAMIA 2026 paper (accuracy / macro F1), all LLMs using `prompt_0004` with Few-Shot and
shared context, no fine-tuning:

| model | setting | accuracy | macro F1 |
|---|---|---|---|
| XLM-RoBERTa | fine-tuned | **0.676** | **0.676** |
| BERTIN | fine-tuned | 0.663 | 0.664 |
| Qwen2.5-7B-Instruct | few-shot | 0.411 | 0.370 |
| GPT-4o-Mini | few-shot | 0.390 | 0.386 |
| XGBoost | fine-tuned | 0.350 | 0.348 |
| Llama-3.1-8B-Instruct | few-shot | 0.326 | 0.296 |
| Majority class | — | 0.250 | 0.250 |

A fine-tuned encoder beats every prompted 7–8B model by more than 25 points. Note also that both
open models nearly abandon Entailment (≈0.08 recall), effectively collapsing the four-way task into
a three-way one.

## Caveat when comparing runs

vLLM applies no content filtering, so open models served locally return a label for all 80,213
pairs. The GPT-4o / GPT-4o-Mini runs went through Azure, whose NSFW filter rejected 44 pairs (40 of
them Neutral). The two bases are therefore not exactly identical, and the missing pairs concentrate
in the sensitive-content source datasets — worth keeping in mind when comparing proprietary and
open-weight numbers pair for pair.
