# Sentiment Lexicon Builder — Sentiment Lexicon and ABSA Design Guide

Methodology for designing and building domain-specific sentiment analysis systems.

## Sentiment Analysis Approach Comparison

| Approach | Advantages | Disadvantages | Best For |
|----------|-----------|---------------|----------|
| Lexicon-based | Fast, interpretable | Domain limitations, ignores context | Small-scale, rapid prototyping |
| ML-based (traditional) | Domain adaptation | Requires training data | When labeled data is available |
| Deep learning (BERT) | Context understanding, high accuracy | Resource-intensive | Large-scale, accuracy-focused |
| LLM (prompt-based) | Zero-shot, flexible | Cost, speed | Diverse domains, small volumes |
