What is Sentiment Analysis

Sentiment analysis is the process of identifying and quantifying the feeling or attitude of a text. Sentiment analysis has gained importance in recent years with the advent of social media. It is used to understand customer sentiment about a company or product and to identify areas where improvement is required. Sentiment analysis can also be used for political purposes, to gauge public opinion about a candidate or policy.

Customer sentiment analysis – meaning

Sentiment analysis or Sentiment analysis is a text-mining tool that can analyze a large number of customer reviews and opinions, the sentiment they convey. Sentiment score tells you what people feel about the product. Sentiment scores from customers help companies to detect negative comments about their products and respond to those sentiments with the appropriate action.

Text sentiment analysis

Text sentiment can be analyzed manually but this is a time-consuming and labor-intensive process. Sentiment analysis can also be done automatically using machine learning algorithms. These algorithms are trained on large data sets that contain positive, negative, and neutral texts. The algorithm then assigns a sentiment score to each text based on its training data. This score can be used to determine the general mood of a text. Sentiment analysis is also used to understand what customers want by analyzing customer reviews.

Why is sentiment analysis important?

Sentiment analysis is important because it gives companies a more accurate customer picture. Sentiment analysis enables companies to get insights into what customers think about their products and services. This can help companies know what customers really want, how they feel about the product, and if there are any areas that need improvement. Sentiment analysis can be used in customer service applications like chatbots and mobile apps like for example Digit platforms use sentiment analysis to understand what users care most about and feed this information back to the business.

Sentiment Analysis using Machine Learning

Machine learning can be applied in sentiment analysis through either supervised or unsupervised learning. Sentiment analysis based on machine learning has been successfully implemented using deep learning, where large datasets are used to train algorithms that can identify patterns and make predictions about new texts. Sentiment analysis is an active area of research with several applications in marketing, market research, business intelligence, etc. Sentiment classification model based on machine learning is being widely utilized for various activities like news classification, spam detection, etc. Sentient beings have brought so much advancement to this world but it’s not enough!

Customer Sentiment Sentiment Analysis – Examples

Here are some examples where sentiment analysis has been used successfully:

Sentence polarity detection

Sentence polarity detection – Sentiment Analysis example – Sentiwordnet Sentence polarity refers to the nature of a sentence – whether it’s positive, negative or neutral – which can be determined by means of sentiment analysis.


Sentiwordnet is a lexical resource for opinion mining and sentiment analysis which contains a semantic network of English words annotated with SentiStrength sentiment scores and part-of-speech tags. Sentiwordnet was used to classify the polarity –positive, neutral, or negative – of movie reviews from an online movie database.

Sentiment Analysis’ Scores and Classifications

When a text is fed into a machine learning algorithm, it returns a score between 0 and 1 that tells you how positive the text is. Sentiment analysis also provides you with two classifications: Positive Sentiment and Negative Sentiment. These are the predefined categories for training data sets that train algorithms to identify them as positive or negative texts. Sentiment analysis can be further broken down into 3 different types: Sentiment Score, Sentiment Classification, and

3 common types of sentiment analysis

1. Sentiment score – This is the simplest form of sentiment analysis that gives a text a score between 0 and 1 that tells you how positive or negative it is as a whole.

2. Sentiment classification – The algorithm assigns each sentence within the text to one of the predefined categories –positive, neutral, or negative – based on its training data set. Generally, this approach is more accurate than Sentiment Score because it assigns sentiment to each sentence within the text.

3. Sentiment identification – Sentiment identification identifies which part of a sentence is positive or negative and labels it accordingly. Sentiments are identified by means of NLP techniques that study the linguistic structure of sentences and identify their grammatical parts such as nouns, verbs, adverbs, etc. Sentiment identification can be used to find out what customers want from texts that contain customer feedback.

NLP Sentiment Analysis


NLP Sentiment Analysis – Sentiment Classifier Sentiment analysis using NLP is the most accurate form of sentiment analysis because it uses natural language processing techniques to identify sentiments within a text. The algorithm breaks down the sentence structure, identifies verbs, nouns, adjectives and adverbs in each sentence, and then analyzes them to determine their parts-of-speech.

Sentiments are identified by means of studying the linguistic properties of sentences that convey positive or negative meaning about a topic. SentiStrength API provides an example of how sentiment scores are calculated for texts. It’s built on the combination of two machine learning algorithms: Naive Bayes and Support Vector Machines (SVM).

For example: this just had to be the perfect day Sentiment score = 0.8 Sentiment classification = Positive Sentiment Sentiment identification = This sentence is positive. Sentiments are identified by means of NLP techniques that study the linguistic structure of sentences and identify their grammatical parts such as nouns, verbs, adverbs, etc.

Sentiment Analysis Strategy for Businesses

In order for sentiment analysis to work effectively, companies must have access to enough data about how people really feel about their products and services. Training algorithms on existing reviews helps in detecting sentiments related to specific keywords or brands found in customer feedback. Sentiment analysis can be used to monitor the social media channels of a business to understand what people are saying about it.
