What is Sentiment Analysis in NLP?
Natural Language Processing (NLP) is a way to understand the actual meanings of the text words, sentences, or entire written documents. NLP is used to train the machines thereby, helping them understand the language and communication process among humans while discussing a topic.
The main motive of sentiment analysis is to find out expressions of people that are eventually classified as positive, negative, or neutral. It can be used in diverse areas such as company products, market research, marketing analysis, customer targeting, product reviews, customer feedback, reputation management, etc.
How Does Sentiment Analysis Work?
As mentioned above, sentiment analysis is used in NLP-based Machine Learning algorithms to develop such AI applications that can understand the ways of linguistic context showing the sentiments of different people.
But the question here is, how does sentiment analysis work? The developers begin by creating a text Machine Learning-based algorithm that can detect the contents showing any specific sentiment indicator.
Afterwards, they train the ML classifier by feeding it a huge quantity of training datasets containing reactions based on positive, negative, and neutral sentiments. Every piece of content is scattered and divided into basic components such as text words, phrases, sentences, and other entities.
Once this process is completed, the relationship between the topics and the identification process commences. Then, AI model assigns a sentiment score to that particular post. The post can range from 1 representing negative and +4 representing 4 positive comments. If a sentiment is neutral, the score is usually given 0.
As we already know, understanding the different human languages is a very complex task due to their cultural and social diversity. Hence, it is important to train the programs in such a way that they are able to detect and analyse grammatical nuances.
TYPES OF SENTIMENT ANALYSIS
To understand the sentiments of people, there are different types of sentiment analysis used in the market. Apart from normal opinions – positive, negative, or neutral, other types of sentiment analysis help in understanding people's inner feelings, their actual intentions, and emotions.
This is one of the most simple and common ways of understanding your customers' sentiments. Yes, fine-grained sentiment analysis helps in studying the ratings and reviews given by the customers.
While analyzing the sentiments, you can use the readily available categories like very positive, positive, neutral, negative, or very negative. Providing a rating option from 1 to 5 is yet another way to scale the feedback given by your customers. Most e-commerce sites use this technique to know the sentiments of their customers.
This type of sentiment analysis is more focused on the aspects of a particular product or service. To make it easier to understand, let's take an example – if you are talking about a soundbar or a wireless speaker system.
Here you can analyze your customer's sentiments by asking them for feedback about the sound quality, connectivity, and other features, making such devices more useful and productive for the users. It helps in determining specific attributes of the product.
Intent-based Sentiment Analysis
To know the intent of the customers; whether they are looking to buy the product or just browsing around, is achievable through intent analysis. It not only helps to identify the intent of the customers but also to track and target them through advertisements or other ways of online promotions.
With intent analysis, companies can save their time, efforts, and cost while targeting the potential customers as per their intentions. This helps in getting a more vivid understanding of the intentions of the customers.
Emotion Detection Sentiment Analysis
As the name symbolizes, this type of sentiment analysis helps to detect and understand the emotions of the people. Emotions like anger, sadness, happiness, frustration, fear, panic, worry, or anxiety, may all be included.
Understanding the sentiments of people using emotion detection is even more difficult as people use a collection of words having a different sense of meaning. Hence, inaccurate emotion detection can lead to an inaccurate decision while analyzing the true sentiments of the people.
How Can Sentiment Analysis be Used?
The main motive of using sentiment analysis is to find out the true feelings of the varied people living in our society. It can be used for analyzing the customer's feedback of a particular company, normal users on social media towards a product, services, social issues, or political agendas.
Companies also use it for brand analysis, reputation crises, campaigns performances, competitor analysis, and improve the service offered to the customers. Analyzing the sentiments of the customers helps the customer support team to prioritize their work for offering better service to end-users.
Why Sentiment Analysis is Difficult?
Sentiment analysis is a very difficult task due to sarcasm. The words or text data implied in a sarcastic sentence come with a different sense of meaning depending on the senders or situations.
Sarcasm is remarking someone opposite of what you want to say. It is expressed to hurt someone's feelings or humorously criticize something. On social media, sarcasm is one of the most common behavior you can see nowadays interfering with the results.
Sarcastic words or texts show the unique behavior of people. It is usually used to convey a negative sentiment using the positive intention of words. This kind of caustic remark can easily mislead the sentiment analysis decisions.
The presence of sarcastic words makes it difficult for sentiment analysis processing in turn making it difficult to develop NLP-based AI models. Hence, a deeper analysis of such words is required to understand the true sentiments of people with accuracy.
In such a case, we can use the psychographic-based analysis to understand such people and their exact intention of what they are trying to say. Using the psychographic segmentation in sentiment analysis can give more comprehensive perception of different kinds of people interacting with each other.
Sentiment Analysis using Psychographic Segmentation
Sentiment analysis can be a big game changer in forming a more focused marketing strategy for the companies. But these establishments need to understand their customers by segmenting them into their characteristics like their cultural values, beliefs, desires, goals, interests, and lifestyle choices.
Psychographic Segmentation becomes helpful here in analyzing the customers' sentiments by segmenting them based on their activities, lifestyle, and interests. It is a more qualitative approach to study consumers according to their psychological characteristics.
Psychographic segmentation not only helps in improving the customer experience but also authorizes companies to offer more tailored products or services to the right customers at the right time improving the return on investment.
Psychographics allows you to learn about the deeper motivations and emotions that influence potential customers. Hence, in the next article, we will learn more about psychographic segmentation, and how it is helpful in sentiment analysis.
