Natural Language Processing (NLP) Text Annotation for AI Training

TextText Generation
Worked on data labeling and annotation projects aimed at improving the performance of AI language models. The project involved annotating and classifying large text datasets used to train Natural Language Processing systems. Responsibilities included tagging text based on sentiment, intent recognition, and topic categorization, as well as evaluating AI-generated responses for relevance, accuracy, and safety. Additionally, I performed dataset quality checks to identify inconsistencies, remove low-quality data, and ensure the training data met machine learning standards. My work contributed to improving AI response quality, model accuracy, and the reliability of conversational AI systems.
