D

Answer to Question 2

1. Sentiment Detection: Here the goal is to differentiate between a fact and an opinion, which may be viewed as classification of text as objective or subjective.
2. N-P Polarity Classification: Given an opinionated piece of text, the goal is to classify the opinion as falling under one of two opposing sentiment polarities, or locate its position on the continuum between these two polarities.
3. Target Identification: The goal of this step is to accurately identify the target of the expressed sentiment.
4. Collection and Aggregation: In this step all text data points in the document are aggregated and converted to a single sentiment measure for the whole document.
