Labeling Experience

Text Labeling & Classification for Automated Review Analysis (Project)

OtherTextClassification
This project encompassed end-to-end pipeline work on a text classification and feature engineering task. The labeling steps involved cleaning text, generating structured features, and evaluating classifier outputs for AI-driven review categorization. Attention was paid to precision, recall, and F1 metrics to gauge annotation signal quality. • Processed large-scale text data for classification and feature extraction. • Trained and evaluated classifiers for sentiment/feature labeling. • Generated and interpreted evaluation results, focusing on label quality. • Developed thematic summaries to enhance insight extraction.

OtherVideoQuestion Answering
This experience involved curating, chunking, and preparing video data for use in a retrieval-augmented Q&A bot. The process covered semantic segmentation, creation of embeddings, and structured evaluation with LLM agents. The main focus was ensuring accuracy and reproducibility of Q&A outputs for user queries derived from video content. • Indexed video data into semantic chunks and generated embeddings for similarity search. • Built LLM agents to answer questions with evidence sourced from video metadata. • Evaluated bot performance with test sets to optimize accuracy. • Documented the experimental process for reliable replication by others.
