TextEvaluation/Rating

Reviewed and evaluated AI-generated responses in Spanish for a B2B SaaS platform serving cosmetology clinics. Tasks included assessing output quality for tone, semantic accuracy, and contextual relevance across automated CRM interactions and AI skin analysis recommendation outputs. Applied judgment criteria based on linguistics and philosophy of language background to identify hallucinations, inconsistencies, and off-tone responses in both formal and conversational Spanish registers.
