🛡️ LexiGuard: Misogyny, Misandry & Toxicity Detection in English and Slovak

LexiGuard is a multilingual multitask model designed to detect and classify offensive language, with a focus on misogyny, misandry, and toxicity levels in English. The model also supports Slovak, making it suitable for multilingual analysis of social media content.

It performs dual classification:

1. Category: Misogyny, Misandry, or Neutral
2. Toxicity level: Low, Medium, or High

The model is based on xlm-roberta-base and was fine-tuned on a custom dataset primarily in English, with additional annotated samples in Slovak.

🧠 Model Overview

• Base model: xlm-roberta-base
• Tasks: Multitask classification (2 output heads)
• Primary language: English
• Secondary language: Slovak
• Use case: Detecting offensive, sexist, or toxic comments in multilingual social media

🛠️ Usage

from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("Megyy/lexiguard")
model = AutoModelForSequenceClassification.from_pretrained("Megyy/lexiguard")

text = "Women are useless in politics."
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)

# outputs.logits contains predictions for both tasks

Note: The model has two output heads:

• Head 1: Category (misogyny/misandry/neutral)
• Head 2: Toxicity (low/medium/high)
