Question
You read a news article and want to create a prompt that will give you the overall sentiment from the article. Which type of prompt would you use?
A. Text classification
B. Factual responses
C. Text extraction
D. Conversation
Answer
A. Text classification
Explanation
To determine the overall sentiment of a news article, the correct prompt type is text classification (A). Here’s why:
Text Classification for Sentiment Analysis
Text classification involves categorizing text into predefined labels—in this case, positive, negative, or neutral sentiment. Sentiment analysis is a specialized form of text classification that evaluates emotional tone, context, and implicit cues in language.
For example:
- A prompt might ask, “Analyze this news article for sentiment. Classify it as positive, negative, or neutral, and explain key phrases that influenced your decision.”
- Steps include identifying sentiment indicators (e.g., “groundbreaking discovery” vs. “controversial decision”), assessing context for sarcasm/irony, and providing reasoning.
Why Other Options Are Incorrect
B. Factual responses: Focus on retrieving objective facts (e.g., dates, names), not emotional tone.
C. Text extraction: Pulls specific data (e.g., quotes, statistics) but doesn’t interpret sentiment.
D. Conversation: Designed for dialogue, not analytical tasks like sentiment classification.
Key Techniques in Sentiment Analysis
Graded analysis: Scores sentiment intensity (e.g., 1–5 scale).
Aspect-based analysis: Evaluates sentiment toward specific entities (e.g., a policy in a political article).
Negation handling: Adjusts for phrases like “not impressive” by marking negated terms (e.g., NOT_impressive).
Practical Applications
- Social media monitoring.
- Brand reputation tracking.
- Customer feedback analysis (e.g., reviews, surveys).
By using text classification prompts, you systematically decode sentiment, ensuring reliable and actionable insights from news articles or other texts.
