Chat-Pulse: Sentiment Analysis & Polarity Detection for Chat Conversations

Overview

Chat-Pulse is a powerful tool for analyzing the sentiment and emotional polarity of chat conversations. Using advanced Natural Language Processing (NLP) and machine learning algorithms, Chat-Pulse processes textual chat data to provide insights into the emotional tone of conversations. Whether you're looking to assess customer satisfaction, monitor team dynamics, or analyze social media interactions, Chat-Pulse helps you unlock valuable insights by automatically determining whether chat conversations are positive, negative, or neutral.

Key Features

1. Sentiment Analysis

• Core functionality: Automatically classifies chat messages into sentiment categories: Positive, Negative, or Neutral.
• Machine Learning Models: Built on robust models trained on large datasets, enabling highly accurate sentiment predictions.

2. Polarity Detection

• Polarity Score: Detects the polarity of chat conversations and provides a score that indicates the overall emotional tone—positive, negative, or neutral.
• Granular Insights: Analyzes not just individual messages but entire conversations, ensuring a complete understanding of chat sentiment trends.

3. Statistics & Metrics

• Sentiment Distribution: Generate detailed statistics that show the percentage distribution of positive, negative, and neutral sentiments across the dataset.
• Sentiment Trends: Track sentiment changes over time to identify patterns, spikes, or shifts in mood.
• Customizable Metrics: Tailor the sentiment analysis output to fit your specific needs (e.g., topic-based sentiment or sentiment by user).

4. Visualization

• Dynamic Graphs: Use data visualization tools like Matplotlib to create clear, informative graphs that showcase sentiment distribution, trends, and overall sentiment intensity.
• Interactive Dashboards: Customize your own dashboards for continuous monitoring and more engaging visual insights.

5. Customization & Extensibility

• Model Fine-tuning: Customize the sentiment analysis model according to your domain-specific needs. Train on your own datasets, adjust parameters, and optimize for your particular use case.
• Flexible Input Formats: Analyze chat data in various formats (CSV, JSON, Text), ensuring compatibility with your existing workflows.
• Pluggable Algorithms: Easily swap out or combine different machine learning models to enhance sentiment detection accuracy.

6. Real-time Analysis

• Instant Sentiment Detection: Analyze chat messages in real-time or batch process large datasets for historical analysis.
• API Integration: Integrate with other applications or services to analyze chat data in real-time, offering immediate insights.

Demo

• Live Demo: A web-based interface for uploading and analyzing chat data is available for testing the tool on sample datasets. [Demo Link] (Insert link here)
• Example Analysis: Take a look at the sample outputs of sentiment analysis for different conversation topics and see how polarity detection is performed.

Installation

To get started with Chat-Pulse, follow the installation instructions below:

Prerequisites

Ensure you have Python 3.7+ installed. Additionally, you need the following Python packages:

• NLTK – Natural Language Toolkit for text processing
• Scikit-learn – Machine learning algorithms and models
• Pandas – Data manipulation and analysis
• Matplotlib – Data visualization

Step 1: Clone the Repository

git clone https://github.com/anandpiyush1521/Chat-Pulse.git

Step 2: Install Required Libraries

Ensure your environment is set up correctly by installing the dependencies:

cd Chat-Pulse
pip install -r requirements.txt

Step 3: Setup Jupyter Notebook

Run Jupyter Notebook in your project directory

jupyter notebook

Usage Guide

• Prepare Your Data: Ensure the chat data is in a structured format (CSV, JSON, or Text files).Each record should represent one chat message or one conversation. Ensure that each record contains the chat message, sender details, and timestamp if needed.

• Data Preprocessing: Before analysis, you may need to clean your chat data:

  • Remove special characters and non-alphanumeric symbols.
  • Tokenize the text into words or phrases.
  • Remove stopwords, punctuation, and common noise that does not contribute to sentiment.

• Run Sentiment Analysis

  • Use the notebook or scripts to run sentiment analysis. The system will automatically classify each chat message into Positive, Negative, or Neutral.
  • The sentiment results will be stored in a new column in your dataset for easy reference.

• Calculate Polarity

  • After sentiment classification, use the Polarity Detection feature to calculate an overall polarity score for the entire dataset.
  • The polarity score can range from -1 (Negative) to 1 (Positive), with 0 indicating a neutral tone.

• Generate Sentiment Statistics

  • Use built-in functions to generate sentiment distribution statistics, such as:
  • Percentage of Positive, Negative, and Neutral messages.
  • Trend Analysis to track sentiment over time.

• Visualization

  • Leverage Matplotlib or Seaborn to visualize the sentiment distribution and trends over time with graphs like:
  • Pie charts showing sentiment percentages.
  • Line plots for sentiment trends over a specific time period.
  • Histograms for sentiment intensity distribution.

• Customization & Fine-tuning

  • Customize the underlying sentiment analysis model by training it on your own labeled dataset.
  • Adjust hyperparameters and experiment with different text feature extraction techniques (e.g., TF-IDF, Word2Vec).

Example Workflow

• Load Data: Import your chat dataset.
• Preprocess: Clean and tokenize the text data.
• Sentiment Analysis: Classify each chat message's sentiment.
• Polarity Detection: Get the overall polarity score.
• Generate Stats: Calculate sentiment distribution and trends.
• Visualize: Create insightful visualizations of your data and analysis.

Real-World Applications

• Customer Support: Analyze the tone of customer service interactions to gauge customer - satisfaction.
• Social Media: Monitor public sentiment around a brand, product, or event.
• Team Communication: Assess the sentiment of internal communication within teams or organizations.
• Marketing: Evaluate sentiment around marketing campaigns, product launches, and brand messaging.
