How it works

Paraphrase Detection helps conversational AI understand that 'how do I reset my password?' and 'I forgot my login, help!' refer to the same underlying intent. This is critical for robust intent recognition, allowing the system to handle varied user phrasings without needing exact matches. It improves the flexibility and user-friendliness of the AI.
