What is the primary function of sentiment analysis?

• A. To quantify financial data for marketing
• B. To classify opinions expressed online as positive, negative, or neutral
• C. To evaluate the effectiveness of advertising campaigns
• D. To assess user interface design

Answer: (B)

The primary function of sentiment analysis is to classify opinions expressed online as positive, negative, or neutral. This process involves the use of natural language processing and machine learning techniques to analyze text data from various sources like social media, reviews, and blogs. By categorizing sentiments, businesses and organizations can gain insights into public perception about their products, services, or topics of interest. This understanding allows them to make more informed decisions and tailor their strategies accordingly, whether in marketing, product development, or customer service. In contrast, the other choices focus on different aspects of data analysis or evaluation. Quantifying financial data pertains to financial analytics rather than sentiment, while assessing advertising effectiveness is related to campaign metrics. User interface design assessment involves usability testing and human-computer interaction principles, which do not directly involve sentiment classification.
