Researchers developed a new Arabic dataset for detecting toxic content on social media. The fine-tuned MARBERTv2 model achieved high accuracy, marking a breakthrough in Arabic toxicity detection.
Area of Science:
- Natural Language Processing
- Social Media Analysis
- Computational Linguistics
Background:
- Online social networks facilitate communication but also host toxic content like hate speech and cyberbullying.
- Existing toxicity detection efforts primarily focus on English, neglecting other languages.
- There is a significant need for resources to address online abuse in Arabic.
Purpose of the Study:
- To create a standard Arabic dataset for toxicity and abuse detection on online social networks (OSNs).
- To evaluate the performance of various machine learning and transfer learning models on this new dataset.
- To advance the field of Arabic natural language processing for content moderation.
Main Methods:
- Construction and expert annotation of a novel Arabic dataset for toxicity detection.
- Experimentation with sixteen machine learning algorithms, FastText, and seven transfer learning architectures.
- Utilized four word embedding techniques: bag of words (BOW), term frequency-inverse document frequency (TF-IDF), FASTTEXT, and bidirectional encoder representations from transformers (BERT).
Main Results:
- The fine-tuned MARBERTv2 model combined with BERT embedding achieved the highest performance.
- Achieved an F1-score of 92.43% and an accuracy of 92.21% in classifying toxic Arabic content.
- Demonstrated the effectiveness of the developed dataset and advanced models for Arabic toxicity detection.
Conclusions:
- The study presents a significant breakthrough in classifying toxic tweets in Arabic.
- Highlights the importance of developing multilingual resources for addressing online toxicity.
- The proposed dataset and MARBERTv2 model offer a robust solution for Arabic content moderation.

Antidotes
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...
Prevention of Further Absorption of Poison
Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Effects of EDTA on End-Point Detection Methods
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
