KLUENLI for SimCSE Dataset

For a better dataset description, please visit: LINK

This dataset was prepared by converting KLUENLI dataset to use it for contrastive training (SimCSE). The code used to prepare the data is given below:

import pandas as pd
from datasets import load_dataset, concatenate_datasets, Dataset
from torch.utils.data import random_split


class PrepTriplets:
    @staticmethod
    def make_dataset():
        train_dataset = load_dataset("klue", "nli", split="train")
        val_dataset = load_dataset("klue", "nli", split="validation")
        merged_dataset = concatenate_datasets([train_dataset, val_dataset])

        triplets_dataset = PrepTriplets._get_triplets(merged_dataset)

        # Split back into train and validation
        train_size = int(0.9 * len(triplets_dataset))
        val_size = len(triplets_dataset) - train_size
        train_subset, val_subset = random_split(
            triplets_dataset, [train_size, val_size]
        )

        # Convert Subset objects back to Dataset
        train_dataset = triplets_dataset.select(train_subset.indices)
        val_dataset = triplets_dataset.select(val_subset.indices)

        return train_dataset, val_dataset

    @staticmethod
    def _get_triplets(dataset):
        df = pd.DataFrame(dataset)

        entailments = df[df["label"] == 0]
        contradictions = df[df["label"] == 2]

        triplets = []

        for premise in df["premise"].unique():
            entailment_hypothesis = entailments[entailments["premise"] == premise][
                "hypothesis"
            ].tolist()
            contradiction_hypothesis = contradictions[
                contradictions["premise"] == premise
            ]["hypothesis"].tolist()

            if entailment_hypothesis and contradiction_hypothesis:
                triplets.append(
                    {
                        "premise": premise,
                        "entailment": entailment_hypothesis[0],
                        "contradiction": contradiction_hypothesis[0],
                    }
                )

        triplets_dataset = Dataset.from_pandas(pd.DataFrame(triplets))

        return triplets_dataset

# Example usage:
# PrepTriplets.make_dataset()
