Sentiment Analysis Project Ideas

Amazon Product Reviews

The first project concept for Sentiment Analysis that is appropriate for beginners involves assessing Amazon product reviews. One of the major online retailers, Amazon, offers a variety of products.

Employing sentiment analysis enables businesses to identify the aspects of their products that customers find appealing while trying to comprehend public opinion. Identifying the main problems with their products also helps.

The raw alpha-numeric text of numerous products from Amazon is scraped to start the sentiment analysis for this project. These reviews must go through a text processing stage where text is generally converted into integers using TFIDF (Term Frequency Inverse Document Frequency). A statement can be classified as "Positive" or "Negative" using a classification model like SVM (Support Vector Machines).

Since firms want specialists to apply sentiment analysis to examine their product reviews for market research, expertise in this topic is in high demand. A novice should start with less well-liked products, while those looking for a challenge should choose a well-liked product and study its reviews.

Rotten Tomatoes Movie Reviews

On the movie and television review website Rotten Tomatoes, critics and moviegoers post their opinions. You can read reviews for almost every TV show, drama, or movie worldwide on the platform. It is a sizable dataset source for the reviews' sentiment analysis.

The study of movie reviews is a classic example of a multi-class model problem since a film can elicit various emotions, including negative, somewhat unfavorable, neutral, positive, and optimistic. Emojis and other special characters can appear in movie reviews, so the extracted data must undergo data normalization.

The entertainment industry takes reviews from critics seriously, and it also assists production companies in understanding why their program or film was successful (or failed). Since consumers read reviews before purchasing movie tickets, critical reviews also affect a drama or film's commercial success. Production companies can determine the general perception of critics using sentiment analysis.

Reviews of Scientific Papers

Because of the widespread misconception that most research publications have positive citations, sentiment analysis of citation contexts in research/review papers is an untapped subject. Furthermore, criticisms are frequently hidden and are rarely apparent in negative quotations. More direct sentiment expressions are required, which is a significant obstacle to accurate polarity recognition.

Finding feelings in research articles needs both simple and complex analyses. When this occurs, rule-based analysis can categorize research papers into multiple classes by comprehending the abstracts utilizing various NLP concepts like Latent Dirichlet Allocation (LDA). LDA models are statistical models that use the "topic-model" notion to infer mathematical intuition from a collection of documents.

Track Customer Sentiment Over Time

The interests and attitudes of the customer fluctuate along with the business. Customers' feelings are impacted when firms launch new product lines or alter the prices of their goods.

You can assess and comprehend client sentiment by following their opinions over time. A change in sentiment score shows your adjustments' emotional resonance with the clients. 

Companies can enhance their products and correct mistakes by monitoring favorable and unfavorable feedback.

Analyze a Company's Reputation

You can select any business to conduct a thorough opinion analysis for this intermediate sentiment analysis project. Using sentiment analysis, you can better grasp the public's perception of the company and its products.

Start by gathering information from relevant sources, such as a company's Facebook and Twitter sites, to see what the general public thinks of it. To determine the public brand perception in the market, analyze the user chats. You can scrape information from numerous review websites for a more thorough examination.

Major Advantages of Sentimental Analysis

Social Media Monitoring

To sift through the social media data and assess the general public mood on each business's social media platform, sentiment analysts must collaborate with machine learning tools. Working on these projects will provide you with experience using various learning software.

Customer Support

This data will be the foundation for processing emails, calls, online chats, and support tickets according to sentiment.
