I find sentiment analysis to be very useful in research for open ended responses. It's an easy way to quickly understand where there are problems to dig deeper into quickly.

2 How does NLP work for sentiment analysis?

NLP utilizes various techniques and algorithms to process and interpret natural language. Tokenization is the process of breaking down the text into smaller units, such as words, phrases, or sentences. Normalization then transforms the text into a standard form, for example, lowercasing, stemming, or lemmatizing. Feature extraction selects the relevant aspects of the text, such as keywords, n-grams, or word embeddings. Finally, classification assigns a label or score to the text, such as positive, negative, or neutral, or a numerical value ranging from -1 to 1.

Sentiment analysis can help companies respond to customers more effectively by understanding the customer's emotion or intent. Sentiment analysis can pinpoint areas within a workflow that require improvement (ex. refund process with a retail company.) It can also help understand the reasons why customers remain loyal.

As an example, I like to use NPS/CSAT measures coupled with opened ended questions as to why people ranked a certain way - this gets you the what and the why. Sentiment analysis helps quickly get to a set of reasons for why respondents perceive an experience a certain way and offer clues as to areas of pain and opportunity.

4 What are the challenges of sentiment analysis for customer feedback?

Sentiment analysis is not a perfect science, and can come with certain challenges and limitations. Natural language is often subjective and ambiguous, making it difficult to detect sarcasm, irony, or humor. Additionally, the same word or phrase may have different meanings or connotations depending on the context or domain. Furthermore, the language and culture of the speaker or writer may affect how a sentiment is expressed or perceived. For example, some languages may use more or less intensifiers, modifiers, or emoticons to convey their sentiments.

Sentiment analysis can also include words that are about the topic of a question itself because it appeared in the responses, but is not particularly useful as direction, so these need to be filtered out.

5 How can you leverage sentiment analysis for customer feedback?

To leverage sentiment analysis for customer feedback, you need to define your goals and scope, choose your tools and methods, collect and preprocess your data, and analyze and visualize your results. For example, what kind of feedback do you want to analyze, what kind of tools or methods do you want to use, what kind of data do you have or need to collect, and how do you evaluate the accuracy and reliability of your results? Additionally, it is important to consider how you can present and interpret the results with charts, graphs, or dashboards.

Presentation to provide easy visual indications is why we use sentiment analysis. It needs to easily provide a quick visual summary of the findings.

Regular review of sentiment analysis will allow you to categorize customer feedback into positive, negative or neutral. Visualizing data in an analytic tool (like Power BI) will uncover top trends, inquires, issues, etc so your team can prioritize which items should be addressed first.
