SeLeRoSa - Sentence-Level Romanian Satire Detection Dataset

Abstract

Satire, irony, and sarcasm are techniques that can disseminate untruthful yet plausible information in the news and on social media, akin to fake news. These techniques can be applied at a more granular level, allowing satirical information to be incorporated into news articles. In this paper, we introduce the first sentence-level dataset for Romanian satire detection for news articles, called SeLeRoSa. The dataset comprises 13,873 manually annotated sentences spanning various domains, including social issues, IT, science, and movies. With the rise and recent progress of large language models (LLMs) in the natural language processing literature, LLMs have demonstrated enhanced capabilities to tackle various tasks in zero-shot settings. We evaluate multiple baseline models based on LLMs in both zero-shot and fine-tuning settings, as well as baseline transformer-based models, such as Romanian BERT. Our findings reveal the current limitations of these models in the sentence-level satire detection task, paving the way for new research directions.

Description

This is the anonymized and processed version of the SeLeRoSa dataset.

The anonymization stage involved using Spacy to replace named entities with tokens:

• Persons → <PERSON>
• Nationalities/religious/political groups → <NORP>
• Geopolitical entities → <GPE>
• Organizations → <ORG>
• Locations → <LOC>
• Facilities → <FAC>

In addition, we replace URLs with the @URL tag. Manual filtering of frequently occurring entities not caught by NER was also performed.

The processing step involved:

• Convert text to lowercase
• Fix diacritics according to Romanian standards
• "ţ" and "ş" (cedilla) vs "ț" and "ș" (comma)
• Tokenize the text using Spacy's tokenizer
• Remove stop words
• Remove punctuation marks
• Remove short tokens (less than 3 characters)
• Lemmatize text using Spacy's Romanian lemmatizer

The code for processing this dataset, including also the experiments, can be found on GitHub.

Usage

First, install the following dependencies:

pip install datasets torch

Example of loading the train set in a dataloader:

from datasets import load_dataset
from torch.utils.data import DataLoader

dataset = load_dataset("unstpb-nlp/SeLeRoSa-proc", split="train")

dataloader = DataLoader(dataset)
for sample in dataloader:
    print(sample)

Dataset structure

The following columns are available for every sample:

Field	Data Type	Description
index	int	A unique identifier for every sentence
news_id	int	A unique identifier for the source news associated with the current sentence
sentence	string	The processed and anonymized sentence
domain	string	The domain associated with the sentence. Can be one of: life-death, it-stiinta, cronica-de-film
label_0	int	The label given by the first annotator. 0 - regular, 1 - satirical
label_1	int	The label given by the second annotator 0 - regular, 1 - satirical
label_2	int	The label given by the third annotator 0 - regular, 1 - satirical
label	int	The aggregated label through majority voting. This should be used for training and evaluation. 0 - regular, 1 - satirical
