Which concept is primarily concerned with the emotional tone expressed in a text?

1. Data modeling

2. Sentiment analysis

3. Text classification

4. Entity recognition

The correct answer is: Sentiment analysis

The concept that focuses on the emotional tone expressed in a text is sentiment analysis. This process involves evaluating and categorizing the emotions or attitudes reflected in text data. By using techniques from natural language processing, sentiment analysis seeks to interpret whether the sentiment is positive, negative, or neutral, and it can even identify specific emotions like joy, anger, or sadness. In contrast, data modeling pertains to the structural representation of data and how different data elements relate to each other, which does not focus on the emotional content of text. Text classification involves categorizing text into predefined groups but is more about organizing information rather than assessing emotion. Entity recognition, on the other hand, identifies and classifies key elements within the text, such as names, dates, and locations, without analyzing the emotional tone. Thus, sentiment analysis is specifically tailored to understanding the emotional nuances present in textual data.
