So without further ado, let’s get started.
What is Sentiment Analysis?
Sentiment analysis is a kind of data mining where you measure the inclination of people’s opinions by using NLP (natural language processing), text analysis, and computational linguistics. We perform sentiment analysis mostly on public reviews, social media platforms, and similar sites. Following are the main types of sentiment analysis:
Fine-grained
Fine-grained sentiment analysis gives precise results to what the public opinion is about the subject. It classified its results in different categories such as: Very Negative, Negative, Neutral, Positive, Very Positive.
Detecting Emotion
This kind of sentiment analysis identifies emotions such as anger, happiness, sadness, and others. Many times, you’ll use lexicons to recognize emotions. However, lexicons have drawbacks too, and in those cases, you’d need to use ML algorithms.
Based on Aspect
In aspect-based sentiment analysis, you look at the aspect of the thing people are talking about. Suppose you have reviews of a smartphone, you might want to see what the people are talking about its battery life or its screen size.
Multilingual
Sometimes organizations need to analyze the text of different languages. This form of sentiment analysis is considerably challenging and requires a lot of effort because you’d need many resources.
Sentiment analysis has many applications in various industries. As it helps in understanding public opinion, companies use sentiment analysis in doing market research and figuring out if their customers like a particular product (or service) or not. Then, according to the findings of the sentiment analysis, the organization can modify the respective product or service and achieve better results.

All in all, it helps companies in understanding their customers better. Companies can serve their customers better when they know where they lag and where they excel.
Why Is Sentiment Analysis Required?
Before we delve into the various sentiment analysis project ideas, such as Twitter sentiment analysis project idea, or sentiment analysis of IBDb reviews, let’s take a look at some of the reasons why Sentiment analysis is important.
In this technology-driven world, a majority portion of the data that we come across is unstructured. Whether it is in the form of emails, texts, or documents, the said data need to be properly structured and then analyzed further. This is where sentiment analysis comes into play. It not only helps to store data in an efficient and cost-friendly manner, but you can also solve certain real-time issues with the help of the same.
Various Approaches Used In Sentiment Analysis
Broadly, there are three main approaches to sentiment analysis. They are-
- Rule-based approach- Unlike the other approaches, the rule-based approach is quite easy to comprehend. It basically counts the total number of negative and positive words present in the data set. Following this, if the result indicates that the number of positive words is more than the number of negative words, then the sentiment is positive, and vice versa.
- Automatic Approach- In this approach, the data set is initially trained, following which predictive analysis is done. After completion of this stage, words are extracted from the text. This can be done with the help of various techniques, some of which might include Linear Regression, Support Vector, and Naive Bayes, among others.
- Hybrid Approach- As the name suggests, this approach is basically an amalgamation of both the rule-based approach and the automatic approach. It delivers more accurate results when compared to the other approaches.
Applications of Sentiment Analysis
There is a wide range of applications for sentiment analysis. Some of them have been discussed in the following list.
- Social Media- The comments on popular social media sites such as Instagram, Facebook, and Twitter are analyzed and then furthermore categorized into different segments, such as positive, negative, and neutral.
- Customer Service- One of the perfect examples might include the comment section in the Google Playstore application, wherein comments from 1 to 5, are usually selected with the help of the various sentiment analysis approaches.
- Marketing Sector- The marketing industry has benefited a lot from sentiment analysis. It has helped brand owners to understand the review of a product or service, and whether it has been categorized as good or bad by the consumers.
In the following points, we’ve discussed some prominent sentiment analysis project ideas, pick one according to your interests and expertise:
Sentiment Analysis Project Ideas
The following are our sentiment analysis projects. Our list has projects for all skill levels so that you can choose comfortably:
1. Analyze Amazon Product Reviews
Amazon is the biggest e-commerce store on the planet. This means it also has one of the largest product selections available. Many times, companies want to understand the public opinion on their product and figure out what’s responsible for the same. For that purpose, they perform sentiment analysis on their product reviews.
It helps them in recognizing the primary issues with their products (if there are any). Some products have thousands of reviews on Amazon while some others only have a few hundred.
It is one of the most sentiment analysis projects because the demand for such expertise is very high. Companies want experts to analyze their product reviews for market research.
You can get the dataset for this project here: Amazon Product Reviews Dataset.
Working on this project will make you familiar with many aspects of sentiment analysis. If you’re a beginner, you can start with a small product and analyze reviews of the same. On the other hand, if you’re looking for a challenge, you can take a popular product and analyze its reviews.
2. Rotten Tomatoes and Their Reviews
Rotten Tomatoes is a review site where you’ll find an aggregate of critics’ opinions on movies and shows. You can find reviews on nearly every show, TV series, or drama there. Admittedly, it’s also a great place to get data from.
You can perform sentiment analysis on the reviews present on this site as a part of your sentiment analysis projects. The entertainment sector takes critic reviews very seriously. By analyzing critic reviews, a production company can understand why its particular title succeeded (or failed). Critic reviews influence the commercial success of a title considerably as well.
With sentiment analysis, you can figure out what’s the general opinion of critics on a particular movie or show. This project is an excellent way for you to figure out how sentiment analysis can help entertainment companies such as Netflix.
You can get the dataset for this project here: Rotten Tomatoes dataset.
3. Twitter Sentiment Analysis
Twitter is a great place for performing sentiment analysis. You can get public opinion on any topic through this platform. This is one of the intermediate-level sentiment analysis project ideas. You should have some experience in performing opinion mining (another name for sentiment analysis) before you work on this task. As it’s a popular project idea, we’ve discussed in a little more detail:
Prerequisites
You should have a basic knowledge of programming. You can either be familiar with Python or R (it’d be great if you’re familiar with both). However, it’s not necessary to have expert-level knowledge of programming. Apart from programming, you should also know how to split datasets and use the RESTful API because you’ll have to use Twitter API here. You should also be familiar with the Naive Bayes Classifier as we’ll be using it to classify our data later in the project.
This project isn’t easy, and it’ll take a little time (downloading data from twitter takes hours).
Working on the Project
First, you’ll need to get authorized credentials from Twitter to use the Twitter API. It takes some time to authorize a Twitter Developer Account, but once you have it, you can go to your dashboard and ‘Create an app’.
After you have the necessary credentials, you can create the function and build a test set. Twitter has a limit on the number of requests one can make through their API, which they have added this limit for security reasons. The ceiling is 180 requests in 15 minutes. You can keep the test set to have 100 tweets.
After creating the test set, you’ll have to build the training set by using Twitter API, which is the hardest part of this project. Make sure that you save the tweets you gather from the API in a CSV file for future use.
After preparing the training set, you only have to preprocess the tweets present in the datasets. Remember, emojis, images, and other non-textual components don’t affect the polarity of sentiment analysis. To include pictures and other parts in your sentiment analysis, you’ll have to use Deep Learning. Make sure that you remove all the duplicate characters and typos from your data. Data cleaning is vital to get the best results possible.
After cleaning the data, you can use the Naive Bayes Classifier for analyzing the dataset available. Finally, you’ll have to test your model and see if it’s producing the desired results or not.
This Twitter sentiment analysis project can help you gain practical experience in handling real-world data, applying sentiment analysis techniques, and interpreting results, making it a valuable project for those looking to enhance their skills in data science and natural language processing.
As you may have realized, this project will take some effort. But performing sentiment analysis on Twitter is a great way to test your knowledge of this subject. It’ll be a great addition to your portfolio (or CV) as well.

Just like the Rotten Tomatoes project we discussed previously, this one will help you learn about the applications of data science and machine learning in the entertainment industry.
Reviews of shows and movies help production companies in understanding why their title failed (or succeeded).
The dataset for this project is quite old and small. But it’s an excellent way for a beginner to test his/her skills on a new dataset. Here’s a link to the dataset: IMDb reviews dataset.
6. Analyze a Company’s Reputation (News + Social Media)
You can pick a company you like and perform a detailed sentiment analysis on it. You can also choose a trending topic and cover it in your sentiment analysis for a more precise result. We can discuss the example of Uber here. They are one of the most prominent startups in the world and have a global customer base. You can perform a sentiment analysis to understand public opinion on this company.
To find the public opinion on Uber, we’ll first start by getting data from the relevant sources, which in this case are Uber’s Facebook page and Twitter page. By analyzing the conversations between the users there, we can figure out the overall brand perception in the market. You’ll need categories to separate different datasets. In this example, you can use Payment, Service, Cancel, Safety, and Price.
Now that we know what we want to work on and where we have to go, we can get started.

Sentiment Analysis on Facebook
We’ll first begin with their Facebook page. It has more than 30,000 comments, and after we perform the analysis under the categories we mentioned previously (Payment, Service, Cancel, Safety, and Price) we found that most of the positive comments were about the Price section. On the other hand, the category with the highest percentage of negative feedback was service. However, while performing this analysis, we also kept in mind that Facebook’s comments are filled with spam, suggestions, news, and various other pieces of information.
For sentiment analysis, we only have to look at opinions.
So, we removed all the unnecessary categories, and as expected, our results changed. Now, negative comments held a majority in all sections, and their ratio in respective categories changed. In Price related comments, the percentage of negative comments rose by 20%.
That’s why it’s essential to perform data cleaning. It helps you get accurate results.

Sentiment Analysis on Twitter
We’ve already discussed the sentiment analysis of tweets in this article. So we’ll follow a similar approach here and analyze people’s tweets where they tag Uber or reply to their tweets. Here, the category with the highest percentage of positive tweets was Payment, and the second-highest was Safety. This also shows how different social media give different results.
However, we would have to perform data cleaning here as well. For that purpose, we’ll remove tweets with unrelated intent (spam, news, marketing, etc.). You’d notice how much the percentage of different categories changes here too.
In our case, Payment saw a decline of 12% in its share of positive tweets and Safety became the category with the highest percentage of positive responses. Apart from that, Safety lost around 2-4% in its share of positive tweets. With this data, you can also find out what are the most popular topics among people when they talk about Uber on these platforms.
So, on Twitter, we found that the most popular categories were payment, Cancel, and service.
You should know that brands take this data very seriously. It helps them figure out what problems they need to work on and how they can solve the same. These tweets are, after all, feedback of customers. In this case, Uber can use the findings of these tweets to understand which parts of its services have faults and how they can fix them.
Sentiment Analysis of News
To understand the public opinion on any organization, you’ll have to analyze the news about it as well. In our example, we’ll check the news articles about Uber. After we analyze the content present in those news articles, we’ll segregate our findings in the categories mentioned above (Payment, Service, Cancel, Safety, and Price).
Apart from that, we’ll also classify different articles according to their popularity. The more popular an article is, the more it’ll affect public opinion. You can measure the popularity of every article according to the number of shares they have. A column with higher shares would undoubtedly be more popular than one with fewer shares.

The Results
In our example, we looked at Uber and the public opinion on this company. After we’ve analyzed Facebook, Twitter, and news, we’d know whether the general sentiment on Uber is positive, negative, or neutral.
You can follow this approach to create sentiment project analysis ideas. You can start with a small company that doesn’t have a high online presence and performs sentiment analysis on multiple channels to understand if it’s perceived positively or negatively. If you want to increase the challenge, you can make it more complicated and perform analysis for a major company (like we did in our example).
7. Hate Speech Detection Model
Apart from the Twitter sentiment analysis project topic, the hate speech detection model is yet another very interesting area to explore in sentiment analysis python. Hate speech basically refers to any kind of communication or language used against a person, or a group, based on their sexuality, race, color, and religion, among other factors. This includes all kinds of verbal, in verbal, written or behavioral communication. The main task of the hate speech detection model is to identify and classify the hate speech from a given text. The same can be achieved by training the model on data, which is used to classify sentiments.
