Text Classification Project

TextClassification
I worked on text classification projects where the main task was to assign labels to sentences and short texts according to predefined categories. The work included sentiment analysis (positive/negative/neutral) and topic categorization, ensuring consistency and accuracy across thousands of examples. I followed strict guidelines to maintain high-quality annotations and contributed to building reliable datasets for AI training in natural language processing.
