In which area are sentiment labels typically applied?

Sentiment labels are primarily applied in the context of customer feedback because this type of data often contains subjective information reflecting how customers feel about a product, service, or brand. By analyzing customer feedback, businesses can better understand their customers' experiences, opinions, and emotions, allowing them to make informed decisions to improve their offerings. Sentiment analysis helps organizations discern positive, negative, or neutral sentiments expressed in written or spoken feedback, leading to actionable insights in customer service, product development, and marketing strategies.

In contrast, while technical reports and financial analyses can contain subjective opinions, they are generally more focused on factual and quantitative data rather than emotional expressions. Inter-departmental emails may include personal opinions, but they are typically geared towards operational or administrative discussions rather than evaluating sentiment. Thus, customer feedback stands out as the primary area where sentiment analysis is most commonly utilized for strategic and operational improvements.
