BlackKakapo/RoSTSC

RO-STS-Corpus

Overview

RoSTSC is a Romanian Semantic Textual Similarity (STS) dataset designed for evaluating and training sentence embedding models. It contains pairs of Romanian sentences along with similarity scores that indicate the degree of semantic equivalence between them.

Dataset Structure

• sentence1: The first sentence in the pair.
• sentence2: The second sentence in the pair.
• score: A numerical value representing the semantic similarity between the two sentences, normalized between 0 and 1.

Data Collection and Processing

The data has been collected from existing datasets, primarily in English, and translated into Romanian. Some datasets were originally in Romanian and were used either in full or in part.

Usage

This dataset can be used for:

• Fine-tuning and evaluating sentence embedding models for Romanian.
• Research on semantic textual similarity and natural language understanding (NLU) in Romanian.

How to Load the Dataset

You can load the dataset using the datasets library from Hugging Face:

from datasets import load_dataset

dataset = load_dataset("BlackKakapo/RoSTSC")

# Access the train split
train_data = dataset["train"]

# View an example
print(train_data[0])

Alternatively, if you have the dataset as a CSV file, you can load it using pandas:

import pandas as pd

df = pd.read_csv("RoSTSC.csv")
print(df.head())

This allows you to easily integrate the dataset into your training or evaluation pipeline.
