Sentiment and topic analysis of Twitter data from major US banking institutions (American Express, Bank of America, Wells Fargo, Capital One, Chase, and Citi) using NLP techniques. The analysis includes LDA topic modeling and sentiment analysis with TextBlob and VADER to identify customer concerns, satisfaction trends, and thematic patterns in banking-related tweets.
Analysis Steps:
- Data Collection & Preprocessing: Load Twitter data from CSV files, clean text, tokenize tweets, remove stopwords, and lemmatize words using NLTK.
- Non-English Word Filtering: Use GloVe word embeddings to filter out non-English and meaningless words.
- Topic Modeling: Perform LDA topic modeling using Gensim to identify key discussion themes. Supports automatic topic discovery via coherence scores.
- Topic Visualization: Generate interactive pyLDAvis visualizations for each bank showing topic-word distributions.
- Sentiment Analysis with TextBlob: Classify tweets as Positive, Neutral, or Negative using TextBlob's polarity scores.
- Sentiment Analysis with VADER: Apply VADER to get compound sentiment scores (-1 to 1) for trend analysis over time.
- Visualization: Create bar/pie charts for TextBlob sentiment distributions and scatter plots with trend lines for VADER scores.
