Labeling Experience

Freelance AI Trainer/Data Extraction Specialist

TextEntity Ner Classification
As a Freelance AI Trainer/Data Extraction Specialist, I focused on developing training datasets to enhance large language models. My responsibilities included web scraping, data cleaning, and transforming raw text into structured formats for AI ingestion. I also performed detailed annotation on content for sentiment, intent, and named entity recognition. • Extracted and cleaned unstructured text from public forums and news sites. • Transformed web data into structured JSON formats with full data integrity. • Annotated datasets for sentiment, intent, and PER/LOC/ORG entities. • Achieved 95%+ accuracy in "Gold Standard" data labeling simulations.
