Introduction

Social media sentiment analysis involves extracting opinions from text data to categorize them into sentiments such as positive, negative, and neutral. This helps in understanding public opinion about various topics, products, or services.

Data Preparation

Objective: Prepare social media sentiment data for analysis.

  1. Load the Data: Import data from a CSV file.
  2. Check for Missing Values: Identify and handle missing values.
  3. Convert Dates: Ensure the date column is in datetime format.
  4. Set Index: Set the date column as the index.
  5. Clean Text Data: Preprocess text data for sentiment analysis.
import pandas as pd

# Load the dataset
data_url = 'https://raw.githubusercontent.com/EdulaneDotCo/kaggle/main/data/social_media_sentimate_data.csv'
df_sentiments = pd.read_csv(data_url)

# Print the first few rows to verify the column names
print(df_sentiments.head())

# Check for missing values
print(df_sentiments.isnull().sum())

# Drop rows with missing values in 'New_Date' and 'clean_tweet' columns
df_sentiments.dropna(subset=['New_Date', 'clean_tweet'], inplace=True)

# Convert 'New_Date' column to datetime
df_sentiments['New_Date'] = pd.to_datetime(df_sentiments['New_Date'])

# Set 'New_Date' as the index
df_sentiments.set_index('New_Date', inplace=True)

# Display the prepared data
print(df_sentiments.head())

Explanation:

  1. Load the Data: We use pd.read_csv to load the sentiment data from a CSV file.
  2. Check for Missing Values: We use df_sentiments.isnull().sum() to identify missing values and drop rows with missing values in the ‘New_Date’ and ‘clean_tweet’ columns using dropna.
  3. Convert Dates: We ensure the ‘New_Date’ column is in datetime format using pd.to_datetime.
  4. Set Index: We set the ‘New_Date’ column as the index using df_sentiments.set_index.

Output:

# Extract compound score
df_sentiments['compound_score'] = df_sentiments['sentiment_scores'].apply(lambda score_dict: score_dict['compound'])

# Categorize sentiments based on compound score
df_sentiments['sentiment'] = df_sentiments['compound_score'].apply(lambda score: 'positive' if score >= 0.05 else ('negative' if score <= -0.05 else 'neutral'))

# Display the sentiment analysis results
print(df_sentiments[['clean_tweet', 'compound_score', 'sentiment']].head())

Explanation:

  1. Install and Import Required Libraries: We use nltk for sentiment analysis.
  2. Load Sentiment Analyzer: We load the VADER sentiment analyzer using SentimentIntensityAnalyzer.
  3. Analyze Sentiments: We calculate sentiment scores for each tweet, extract the compound score, and categorize the sentiments into positive, negative, or neutral.

Trend Visualization

Objective: Visualize sentiment trends over time.

  1. Resample Data: Aggregate sentiment counts on a daily basis.
  2. Plot Sentiment Trends: Visualize the trends of positive, negative, and neutral sentiments over time.
import matplotlib.pyplot as plt

# Resample data to daily sentiment counts
# Initialize an empty DataFrame to store daily sentiment counts
df_daily_sentiments = pd.DataFrame(index=pd.date_range(start=df_sentiments.index.min(), end=df_sentiments.index.max()))

# Aggregate sentiment counts by day
df_daily_sentiments['positive'] = df_sentiments[df_sentiments['sentiment'] == 'positive'].resample('D').size()
df_daily_sentiments['negative'] = df_sentiments[df_sentiments['sentiment'] == 'negative'].resample('D').size()
df_daily_sentiments['neutral'] = df_sentiments[df_sentiments['sentiment'] == 'neutral'].resample('D').size()

# Fill NaN values with 0 to represent days with no sentiments
df_daily_sentiments.fillna(0, inplace=True)

# Plot sentiment trends
plt.figure(figsize=(12, 6))
plt.plot(df_daily_sentiments.index, df_daily_sentiments['positive'], label='Positive', color='g')
plt.plot(df_daily_sentiments.index, df_daily_sentiments['negative'], label='Negative', color='r')
plt.plot(df_daily_sentiments.index, df_daily_sentiments['neutral'], label='Neutral', color='b')
plt.title('Sentiment Trends Over Time')
plt.xlabel('Date')
plt.ylabel('Count')
plt.legend()
plt.show()

Explanation:

  1. Resample Data: We resample the sentiment data to aggregate counts on a daily basis using resample and size for each sentiment category (positive, negative, neutral). We initialize an empty DataFrame df_daily_sentiments with a date range from the minimum to the maximum date in the dataset to ensure all dates are represented.
  2. Fill NaN Values: We fill any NaN values with 0 to represent days with no sentiments.
  3. Plot Sentiment Trends: We use matplotlib to plot the trends of positive, negative, and neutral sentiments over time.

Report Generation

Objective: Generate reports to summarize insights from the sentiment analysis.

  1. Summarize Data: Create summary statistics of sentiments.
  2. Generate Plots: Save plots of sentiment trends.
  3. Export to CSV: Export the summarized data to a CSV file.
# Summarize data
sentiment_summary = df_daily_sentiments.describe()

# Generate plots and save them
plt.figure(figsize=(12, 6))
plt.plot(df_daily_sentiments.index, df_daily_sentiments['positive'], label='Positive', color='g')
plt.plot(df_daily_sentiments.index, df_daily_sentiments['negative'], label='Negative', color='r')
plt.plot(df_daily_sentiments.index, df_daily_sentiments['neutral'], label='Neutral', color='b')
plt.title('Sentiment Trends Over Time')
plt.xlabel('Date')
plt.ylabel('Count')
plt.legend()
plt.savefig('sentiment_trends.png')
plt.show()

# Export summarized data to CSV
sentiment_summary.to_csv('sentiment_summary.csv')

print("Report generated: 'sentiment_summary.csv' and 'sentiment_trends.png'")

Explanation:

  1. Summarize Data: We create summary statistics of the daily sentiment counts using describe.
  2. Generate Plots: We plot the sentiment trends and save the plot as an image file.
  3. Export to CSV: We export the summary statistics to a CSV file using to_csv.

🚀 Why Sentiment Analysis?

Social media sentiment analysis is a powerful tool to understand public opinion on various topics, products, and services. By categorizing sentiments into positive, negative, and neutral, businesses and researchers can make informed, data-driven decisions.

🛠️ Project Breakdown

1. Data Preparation

We start by preparing our social media sentiment data, ensuring it is clean and ready for analysis.

import pandas as pd

# Load the dataset
data_url = 'https://raw.githubusercontent.com/EdulaneDotCo/kaggle/main/data/social_media_sentimate_data.csv'
df_sentiments = pd.read_csv(data_url)

# Check for missing values and drop rows with missing 'New_Date' and 'clean_tweet'
df_sentiments.dropna(subset=['New_Date', 'clean_tweet'], inplace=True)

# Convert 'New_Date' to datetime and set as index
df_sentiments['New_Date'] = pd.to_datetime(df_sentiments['New_Date'])
df_sentiments.set_index('New_Date', inplace=True)
2. Sentiment Analysis

Next, we perform sentiment analysis using NLTK’s VADER sentiment analyzer to categorize the sentiments of each social media post.

import nltk
from nltk.sentiment.vader import SentimentIntensityAnalyzer

# Download VADER lexicon and initialize the sentiment analyzer
nltk.download('vader_lexicon')
sid = SentimentIntensityAnalyzer()

# Calculate sentiment scores and categorize sentiments
df_sentiments['sentiment_scores'] = df_sentiments['clean_tweet'].apply(lambda tweet: sid.polarity_scores(tweet))
df_sentiments['compound_score'] = df_sentiments['sentiment_scores'].apply(lambda score_dict: score_dict['compound'])
df_sentiments['sentiment'] = df_sentiments['compound_score'].apply(lambda score: 'positive' if score >= 0.05 else ('negative' if score <= -0.05 else 'neutral'))
3. Trend Visualization

We then visualize the sentiment trends over time, which helps in understanding how sentiments change across different periods.

import matplotlib.pyplot as plt

# Aggregate daily sentiment counts
df_daily_sentiments = df_sentiments.resample('D').size().unstack(fill_value=0)

# Plot sentiment trends
plt.figure(figsize=(12, 6))
df_daily_sentiments.plot(title='Sentiment Trends Over Time', xlabel='Date', ylabel='Count', figsize=(12, 6))
plt.show()
4. Report Generation

Finally, we generate a report summarizing our findings, including visualizations and export the data for further analysis.

# Summarize data and export to CSV
sentiment_summary = df_daily_sentiments.describe()
sentiment_summary.to_csv('sentiment_summary.csv')

# Save the plot as an image
plt.savefig('sentiment_trends.png')
print("Report generated: 'sentiment_summary.csv' and 'sentiment_trends.png'")
