pysentimentanalyzer 0.1.0

Perform sentiment analysis on text

pysentimentanalyzer

This package performs sentiment analysis on the given texts and summarizes information from the text.

When a survey asks for written comments, it is often tedious to read through every response to extract useful information or just to get a quick summary. By using this package, responses can be quickly summarized to get a general idea of the sentiments of the comments, which can be useful such as when a PR team wants to know the overall sentiment on a company or when instructors want to know the overall sentiment on a course. The goal is to provide a quick summary that is easily interpretable by combining results from a pre-trained Python natural language processing package with the use of visualizations.

Installation

pip install pysentimentanalyzer

Usage

This package provides the following 4 functions:

• generate_wordcloud - Create a wordcloud of the most common positive and negative words.
• get_aggregated_sentiment_score - Calculates the overall sentiment score of the input texts.
• likert_scale - Converts the sentiment score to a likert scale ranging from 1-7.
• sentiment_score_plot - Creates a binned histogram showing count of reviews against the sentiment score.

In general, all functions will take a Pandas DataFrame of strings as an input.

Similar Packages

While there exists many packages and libraries for sentiment analysis and many projects built on top of those packages, we could not find specific packages that combines the use of sentiment analysis with visualizations. However, we expect there to be many projects done by individuals that likely perform similar functions by making use of existing NLP packages. Our package aims enhance the existing NLP packages by providing a quick and simple way to generate summary visualizations. Some Python packages that perform sentiment analysis include:

• spaCy
• VADER
