[Sentiment Analysis](https://en.wikipedia.org/wiki/Sentiment_analysis) (Also called opinion mining) is an approach to NLP that computationally identifies and categorizes mixed opinions (positive, negative, or neutral) in a piece of text. It is usually done to identify the writer's tone and attitude toward a particular topic, product, object, etc.

Businesses are applying popular sentiment analysis tools to many use cases, like social media monitoring, customer support management, and analyzing customer feedback.

**Note:** _In this article, we will talk about some excellent open-source Sentiment Analysis Projects/Repositories that you can use in your projects in 2023. To read more about each, I recommend following the link given along the project._

## Courses from DataCamp
Learning isn’t just about being more competent at your job, it is so much more than that. [Datacamp](https://datacamp.pxf.io/x9nmvv) allows me to learn without limits.

[Datacamp](https://datacamp.pxf.io/x9nmvv) allows you to take courses on your own time and learn the fundamental skills you need to transition to a successful career.

[Datacamp](https://datacamp.pxf.io/x9nmvv) has taught me to pick up new ideas quickly and apply them to real-world problems. While I was in my learning phase, [Datacamp](https://datacamp.pxf.io/x9nmvv) hooked me on everything in the courses, from the course content and TA feedback to meetup events and the professor’s Twitter feeds.

Here are some of my favorite courses I highly recommend you to learn from whenever it fits your schedule and mood. You can directly apply the concepts and skills learned from these courses to an exciting new project at work or at your university.

Pattern is a web-mining module in [Python](https://www.python.org/) for performing Data Mining, Natural Language Processing, Machine Learning, and Network Analysis tasks. The library is comprehensively tested with 350+ unit tests and comes bundled with 50+ examples under the [BSD license](https://en.wikipedia.org/wiki/BSD_licenses).

Pattern supports Python 2.5+ versions and requires [NumPy](https://numpy.org/) installed. It can be directly installed using the [PyPi](https://pypi.org/) package in Python:

`$ pip install pattern`

Patterns provide support for the following applications:

- Data Mining on web services like Google, Twitter, Wikipedia, Web Crawler, HTML DOM parser
- NLP for sentiment analysis, n-gram search, WordNet, part-of-speech taggers
- Machine Learning algorithms like Clustering, Classification, KNN, SVM, Perceptron, Vector Space Model
- Network Analysis using Graph Centrality and Visualization

## 2. ABSA-PyTorch
**GitHub:** https://github.com/songyouwei/ABSA-PyTorch
**GitHub Stars:** 1.7K
**GitHub Forks:** 491
**Languages:**  Python (100%)

[Aspect-Based Sentiment Analysis (ABSA)](https://www.sciencedirect.com/topics/computer-science/aspect-based-sentiment-analysis#:~:text=There%20are%20different%20types%20of%20sentimental%20analysis.&text=Aspect%2Dbased%20sentiment%20analysis%3A%20A,of%20a%20product%20or%20service.) is a sub-technique in sentiment analysis that divides text data to define its sentiments based on its aspects. This project is a PyTorch-Python implementation of ABSA. 

You need PyTorch, numpy, sklearn, Python (3.6 or 3.7), and transformers to install this library. All the implemented models are listed in this [folder](https://github.com/songyouwei/ABSA-PyTorch/tree/master/models) and its recommended to try [PyABSA](https://github.com/yangheng95/PyABSA) for flexible training, inference, and aspect term extraction.

## 3. StockSight
**GitHub:** https://github.com/shirosaidev/stocksight
**Official Documentation:** https://shirosaidev.github.io/stocksight/
**GitHub Stars:** 1.6K
**GitHub Forks:** 386
**Languages:**  Python (97.9%), Shell(1.4%), Dockerfile(0.7%)

![Image description](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/bzjpm7if023bhmyuo2jp.png)

StockSight is a stock market analyzer and predictor tool that uses [Elasticsearch](https://en.wikipedia.org/wiki/Elasticsearch), [Twitter](https://twitter.com/), News headlines, NLP, and Sentiment Analysis in Python. This library helps you find out how much emotions on Twitter and different news headlines affect a stock's price by storing and analyzing the data for stocks. 

It stores Twitter and news headlines, analyzes the emotions of what the author writes, and then does sentiment analysis on the text to specify what the author feels about the stock. 

You can use this project to find not just the sentiments of stocks but also the sentiments of anything. 

> **Note:** You can get support and help from the community members by joining their StockSight Slack channel.

Twitter sentiment analysis is a project for performing sentiment analysis on tweets using various machine learning algorithms and extracted features. This project uses various machine learning algorithms to generate a model [ensemble](https://en.wiktionary.org/wiki/ensemble#:~:text=ensemble%20(plural%20ensembles),chorus%20of%20a%20ballet%20company.). 

The dataset is preprocessed and prepared for the training of the model. The model is trained on the below classifiers:

- Naive Bayes
- Maximum Entropy
- Random Forest
- Decision Trees
- XGBoost
- SVM
- Multi-Layer Perceptron
- Convolutional Neural Networks
- Recurrent Neural Networks
