Sentimental Analysis Project in Machine Learning

Sentiment analysis, often known as opinion mining, is a straightforward process of determining the feelings of a text’s author. What was the writer’s intention when he or she wrote something?

To find out what may be subjective information, we employ a variety of natural language processing (NLP) and text analysis technologies. For better categorization and data manipulation, we must detect, extract, and quantify such information from the text. Natural language processing, or NLP, is the foundation upon which sentiment analysis is based. Natural language processing is a subset of Machine Learning that is concerned with extracting information from text.

NLP is the field of AI that deals with texts, allowing machines to interpret and infer meaning from them. It comprises anything from counting the number of words to a machine producing a tale that is indistinguishable from human texts for jobs like a virtual assistant, query resolution, establishing and sustaining human-like dialogues, summarising texts, spam detection, sentiment analysis, and so on.

What is Sentimental Analysis?

Sentiment analysis (also known as opinion mining) is a natural language processing (NLP) approach for determining the positivity, negativity, or neutrality of data. Sentiment analysis is frequently used on textual data to assist organizations in tracking brand and product sentiment in consumer feedback and better understanding customer demands.

Why do we need Sentimental Analysis?

Sentiment analysis is quickly becoming a crucial tool for monitoring and understanding sentiment in all forms of data, as individuals communicate their ideas and feelings more openly than ever before. 

Brands can learn what makes consumers happy or irritated by automatically evaluating customer feedback, such as comments in survey replies and social media dialogues. This helps them to customize products and services to match their customers’ demands. Using sentiment analysis might help organizations figure out why consumers are pleased or unhappy at each point of the customer journey.

Example of Sentimental Analysis Project

Here are some examples to help you understand the purpose and problems of the sentimental analysis project:-

  • Social media monitoring
  • Brand monitoring
  • Customer support analysis
  • Customer feedback analysis
  • Market research

Most Popular Sentimental Analysis Project

Amazon Product Reviews

The first Sentimental Analysis project idea for beginners is to evaluate Amazon product reviews. Amazon is among the most popular e-commerce sites, with a large product range. When businesses want to know what their consumers think about their products, they may use sentiment analysis to find out. It also aids in identifying the key flaws in their products.

Scraping raw alpha-numeric text of numerous items from Amazon is the starting point for this sentimental analysis project. These reviews must go through a text processing stage, which converts text into numbers largely using TFIDF (Term Frequency Inverse Document Frequency). SVM (Support Vector Machines) classification models of machine learning may identify a statement as ‘Positive’ or ‘Negative.’

Companies are looking for specialists to utilize sentiment analysis to assess existing customer reviews for market research, therefore this project is in high demand. Beginners should start with less popular items, while those looking for a challenge could choose a popular product and study reviews.

Rotten Tomatoes Movie Reviews

Rotten Tomatoes is a website where reviewers and movie lovers write reviews for movies and television series. Almost every TV series, program, or drama from practically every language has been reviewed on the platform. It’s a large dataset that may be used to do sentiment analysis on the reviews. An excellent dataset for a sentimental analysis project.

The movie review sentiment analysis is a classic model problem since a movie can have multiple sentiments — negative, somewhat negative, neutral, fairly positive, and positive. Since a movie review can have additional characters such as emojis, the extracted data has to go through data normalization. Text processing steps like tokenization and the number of occurrences of words within the text can be conducted by using the NLTK (natural language toolkit) library.

The entertainment business takes critical evaluations significantly, and it also aids production firms in determining why a series or film was successful (or failed). People consult reviews before purchasing movie tickets, therefore critics’ reviews have an effect on the business
success of a play or film. Production houses can employ sentiment analysis to determine what the general view of critics is.

IMDb Reviews

A machine learning sentimental analysis project is the next project on our list. IMDb, like Rotten Tomatoes, is an entertainment review website where users may offer their thoughts on various films and television shows. You may use sentiment analysis to figure out what the audience loved and hated about the show. This sentimental analysis project for beginners will teach you about machine learning and data science in the entertainment business.

In any language, a movie review usually contains certain common terms like articles, parts of speech, pronouns, punctuations, and so on. Stopwords are a type of repeating term that does not contribute much information to a text. Stopwords are effectively removed from text processing using NLP packages like spaCY. Because the dataset may only include significant terms, the dataset would be smaller, and multi-class model performance would increase.

These findings can help production firms figure out why their film succeeded or failed. Beginners may put their talents to the test with the little IMDb reviews dataset. For a more advanced version of the project, you may utilize the IMDb Dataset containing 50k movie reviews.

Facebook Comments Sentiment Analysis

Let’s start with the Facebook page. It contains over 30,000 comments, and after analyzing them under the previously specified categories (Payment, Service, Cancel, Safety, and Price), we discovered that the Price area received the majority of the favorable feedback. The category with the largest percentage of negative feedback, on the other side, was service. However, we kept in mind when doing this study that Facebook’s comments are full of spam, ideas, news, and other bits of information.

As a consequence, we eliminated all of the unneeded categories, and our findings altered as predicted. Negative comments now outnumber positive comments in all areas, and the ratio in each category has shifted. The percentage of unfavorable remarks in price-related comments increased by 20%. It’s for this reason that data cleansing is critical. It assists you in obtaining precise findings.
