Why Neuro-Symbolic AI?

Neuro-Symbolic AI requires a fraction of the data compared to deep learning, it is unbiased, so you can track and understand precisely why it's making a decision. As it detects cyberviolence, it can take action, intervene autonomously, or even notify moderators before the damage is done.

Profanity and Personal Attacks are not Mutually Exclusive

Samurai understands nuanced forms of communication from context to intent. Our language models manage the distinction between profanity and personal attacks, it also understands the difference between language targeted at first party or third party. Standard models for precision detection include profanity, sexual remarks, rejection, personal attacks, threats, and sexual harassment.

Our Unique Approach

Samurai takes a Neuro-Symbolic approach to detect hidden meanings in usernames. Identifying individual words within the username and generating as many variants as possible. We use these techniques to find the original attempt at creating a disruptive username. This method allows us to categorize different types of subversive language in a user's online identity.

% Increase in Disruptive Behavior Based on Username

Detailed output

Decomposition of the username - DigBildo - Big D*ldo
Categories - Offensive, Sexual
Toxic Element - D*ldo


Inappropriate - P41nbowRub3s - Rainbow Pubes
Offensive - D34thToFurr1es - Death to furries
Profanity - FolyHuck - Holy F*ck
Sexual - Aneed Morehead - I need more head

Simple Ideas Require Complex Solutions

Filter or keyword-based methods are inefficient & inaccurate. Leetspeak, numeric, and character workarounds require a nuanced understanding of composition, Samurai protects your communities from these adversarial attacks and more "creative" approaches.
