## Introduction
Sentiment Analysis (SA) happens at various levels:
- Document-level SA evaluate sentiment of a single entity (i.e. a product) from a review document.
- Sentence-level SA evaluate sentiment from a single sentence.
- Aspect-level SA performs finer-grain analysis. For example, the sentence “the iPhone’s call quality is good, but its battery life is short.” evaluates two aspects: call quality and battery life, of iPhone (entity). The sentiment on iPhone’s call quality is positive, but the sentiment on its battery life is negative. (Liu 2012)
