RemotasksTextRLHFEntity Ner Classification

As a Senior Data Annotator at Remotasks (Scale AI Partner), I annotated diverse datasets across text, image, and audio modalities for LLM and AI model training. I specialized in tasks including RLHF, NER, part-of-speech tagging, coreference, dependency parsing, and various computer vision annotations. My accuracy consistently exceeded 97%, and I reviewed and audited peer annotations for quality assurance. • Performed RLHF tasks such as rating AI-generated responses for helpfulness, harmlessness, and accuracy. • Labeled entities, part-of-speech tags, coreference chains, and dependency parses for NLP pipelines. • Conducted computer vision labeling including bounding box, polygon, segmentation, and keypoint annotation. • Ensured strict adherence to guidelines from clients like OpenAI and Cohere, escalating edge cases as needed.
