How to Create Sentiment Analysis Graphs from X (Twitter) Comments on a Specific Thread Using Python

by

Sentiment analysis on comments from a specific thread on X (formerly Twitter) is a great way to visually understand the overall mood of a conversation. By analyzing comments, you can identify whether the sentiments are positive, negative, or neutral, which is helpful for engaging with your audience or understanding the reaction to a post.

In this guide, we will walk through the process of extracting comments from a specific thread on X, performing sentiment analysis using Python, and visualizing the results with graphs.

Step 1: Setting Up the Environment

Before diving into the analysis, make sure you have the required tools installed.

  1. Install Necessary LibrariesYou’ll need libraries such as tweepy for accessing the X API, TextBlob or VADER for sentiment analysis, and matplotlib or seaborn for graphing.Open your terminal or command prompt and install them:
pip install tweepy
pip install textblob
pip install vaderSentiment
pip install matplotlib
pip install seaborn

Step 2: Accessing X API for Data Extraction

To fetch comments from a specific thread on X, you need to access X’s API. Follow these steps:

  1. Create a Twitter Developer Account
    • Go to Twitter Developer and apply for API access.
    • Once approved, create a new App to get your API keys.
  2. Authenticate with the APIUse Tweepy to interact with the X API. Here’s how to set up authentication:
import tweepy

# Your X API credentials
consumer_key = 'your_consumer_key'
consumer_secret = 'your_consumer_secret'
access_token = 'your_access_token'
access_token_secret = 'your_access_token_secret'

# Authenticate using Tweepy
auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)

api = tweepy.API(auth, wait_on_rate_limit=True)

Step 3: Extracting Comments from a Specific Thread

To extract the comments from a specific tweet/thread, use the tweepy.Cursor to fetch replies to a tweet.

  1. Get the Tweet ID
    First, you need to get the Tweet ID for the specific thread. You can do this by either extracting it from the URL of the tweet or using the X API to fetch it.Example URL: https://twitter.com/user/status/ID
  2. Fetch Replies Using Tweepy
    Here’s how to fetch the replies to a particular tweet using its ID:
tweet_id = 'tweet_id_here'
replies = []

# Fetching replies to the tweet
for tweet in tweepy.Cursor(api.search_tweets, q='to:username', since_id=tweet_id, tweet_mode='extended').items():
    if hasattr(tweet, 'in_reply_to_status_id_str'):
        if tweet.in_reply_to_status_id_str == tweet_id:
            replies.append(tweet.full_text)

print(f"Total replies fetched: {len(replies)}")

This code will give you the text of all replies to the specified tweet. You can further filter or clean this data if needed.

    Step 4: Performing Sentiment Analysis

    Now that we have the comments, we will perform sentiment analysis to classify each comment as positive, negative, or neutral.

    1. Using TextBlob for Sentiment AnalysisTextBlob is simple to use for basic sentiment analysis. It returns a polarity score between -1 (negative) and 1 (positive).
    from textblob import TextBlob

sentiments = []

for comment in replies:
    # Perform sentiment analysis
    blob = TextBlob(comment)
    sentiment_score = blob.sentiment.polarity
    
    if sentiment_score > 0:
        sentiment = 'Positive'
    elif sentiment_score < 0:
        sentiment = 'Negative'
    else:
        sentiment = 'Neutral'
    
    sentiments.append(sentiment)

print(sentiments)

    Alternatively, you can use VADER (Valence Aware Dictionary and sEntiment Reasoner) for more accurate sentiment analysis on social media comments.

    Using VADER Sentiment Analysis

    VADER works especially well for social media text, as it accounts for emojis, abbreviations, and slang.

    from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer

analyzer = SentimentIntensityAnalyzer()
sentiments = []

for comment in replies:
    sentiment_score = analyzer.polarity_scores(comment)
    
    if sentiment_score['compound'] >= 0.05:
        sentiment = 'Positive'
    elif sentiment_score['compound'] <= -0.05:
        sentiment = 'Negative'
    else:
        sentiment = 'Neutral'
    
    sentiments.append(sentiment)

print(sentiments)

    Step 5: Visualizing the Sentiment Data

    Once you have classified the sentiments of all the comments, it’s time to visualize the results. We will create a bar chart to show the distribution of sentiments (Positive, Negative, and Neutral).

    1. Plotting the Sentiment Distribution
    import matplotlib.pyplot as plt
import seaborn as sns

# Count the occurrences of each sentiment
sentiment_counts = {sentiment: sentiments.count(sentiment) for sentiment in ['Positive', 'Negative', 'Neutral']}

# Prepare the data for plotting
sentiment_labels = list(sentiment_counts.keys())
sentiment_values = list(sentiment_counts.values())

# Create a bar plot
plt.figure(figsize=(8,6))
sns.barplot(x=sentiment_labels, y=sentiment_values, palette='viridis')
plt.title("Sentiment Analysis of Comments on the X Thread")
plt.xlabel("Sentiment")
plt.ylabel("Count of Comments")
plt.show()

    This will generate a graph showing how many comments fall into each sentiment category.

    Step 6: Further Enhancements

    • Word Cloud: You can visualize common words in the comments using a Word Cloud to identify trending topics or keywords.
    from wordcloud import WordCloud

all_comments = " ".join(replies)
wordcloud = WordCloud(width=800, height=400, background_color="white").generate(all_comments)

plt.figure(figsize=(10,8))
plt.imshow(wordcloud, interpolation="bilinear")
plt.axis('off')
plt.show()
    • Time-based Sentiment: Analyze how the sentiment evolves over time by plotting sentiment scores against the time each comment was posted.

    Step 7: Automating the Process

    To continuously monitor sentiment on a thread, you can automate this process to run at regular intervals, updating the sentiment analysis and graph. Set up a cron job (or use Task Scheduler on Windows) to run your Python script periodically.

    Conclusion

    With this guide, you can create insightful sentiment analysis graphs for comments on any specific thread on X. Not only can you analyze the mood of the conversation, but you can also dive deeper into trends and changes over time. Whether you’re analyzing reactions to your latest post or tracking public sentiment on a trending topic, this process provides a valuable tool for understanding your audience and enhancing engagement.

    Happy coding, and may your sentiment graphs always lean positive!
