Basic Sentiment Analysis with VADER: Understanding Customer Feedback Sentiments

This Python script performs sentiment analysis on a list of sample customer feedback using the VADER (Valence Aware Dictionary and Sentiment Reasoner) sentiment analysis tool from the NLTK (Natural Language Toolkit) library.

Importing Libraries

The code begins by importing the necessary libraries. It imports the NLTK library, specifically the SentimentIntensityAnalyzer class from the nltk.sentiment.vader module. VADER is a lexicon and rule-based sentiment analysis tool designed for text sentiment analysis.

# Import necessary libraries
import nltk
from nltk.sentiment.vader import SentimentIntensityAnalyzer

Sample Customer Feedback

The code defines a list named feedback containing three sample customer feedback sentences. These sentences represent different sentiments: positive, negative, and neutral.

# Sample customer feedback
feedback = [
    "I love this product! It's amazing!",
    "The customer service was terrible.",
    "The quality of the product is excellent.",
]

Initializing the Sentiment Analyzer

The script initializes the sentiment analyzer by creating an instance of the SentimentIntensityAnalyzer class and storing it in the variable sia.

# Initialize the sentiment analyzer
sia = SentimentIntensityAnalyzer()

Sentiment Analysis Loop

The code then enters a loop to perform sentiment analysis on each sentence in the feedback list. For each sentence, the polarity_scores method of the SentimentIntensityAnalyzer is used to calculate sentiment scores. The polarity_scores method returns a dictionary with four sentiment scores: positive, negative, neutral, and compound.

# Perform sentiment analysis on each feedback
for sentence in feedback:
    sentiment_scores = sia.polarity_scores(sentence)
    
    # Determine sentiment based on the compound score
    if sentiment_scores['compound'] >= 0.05:
        sentiment = 'Positive'
    elif sentiment_scores['compound'] <= -0.05:
        sentiment = 'Negative'
    else:
        sentiment = 'Neutral'

Printing Results

Finally, the code prints each feedback sentence and its determined sentiment (Positive, Negative, or Neutral).

# Print feedback and sentiment
    print(f"Feedback: '{sentence}'")
    print(f"Sentiment: {sentiment}\n")

Output

The output of the code will display the sentiment of each feedback sentence, whether it’s “Positive,” “Negative,” or “Neutral,” based on the sentiment analysis performed by the VADER sentiment analysis tool. Here’s what the output might look like for the provided sample feedback sentences:

Feedback: 'I love this product! It's amazing!'
Sentiment: Positive

Feedback: 'The customer service was terrible.'
Sentiment: Negative

Feedback: 'The quality of the product is excellent.'
Sentiment: Positive

In this example, the code analyzes three feedback sentences and determines their sentiment. The first and third sentences are classified as “Positive,” while the second sentence is classified as “Negative.”

This code is a basic example of sentiment analysis using the VADER tool, which is particularly useful for analyzing text data focusing on social media content and short informal text. It’s important to note that VADER is a pre-trained lexicon-based model and doesn’t require training on specific datasets. Instead, it relies on a predefined lexicon of words and their associated sentiment scores to analyze text sentiment.
