+# Chatbot Implementation Project
+
+## AIM
+To develop a chatbot using Natural Language Processing (NLP) and a Naive Bayes classifier for intent classification. The chatbot takes user input, predicts the intent, and generates an appropriate response based on predefined intents and responses stored in a CSV file.

+## LIBRARIES NEEDED
+
+??? quote "LIBRARIES USED"
+    - nltk
+    - scikit-learn
+    - numpy
+    - pickle
+
+

+
+
+### DESCRIPTION
+
+??? info "What is the Requirement of the Project?"
+    -A chatbot is required to automate conversations and provide immediate responses to user queries. It can be used to answer  FAQs, provide customer support, and improve user interaction.
+
+??? info "Why is it Necessary?"
+    - Chatbots are essential for improving user engagement and providing 24/7 service.
+    - They automate responses, saving time and providing immediate help.
+
+??? info "How is it Beneficial and Used?"
+    - Chatbots can be used for:
+    1. Customer service automation.
+    2. Answering user questions.
+    3. Guiding users through processes on websites or apps.
+
+
+####  "Initial Thoughts and Planning"
+   - **Intents and Responses**: Gathered and stored in CSV format.
+   - **Preprocessing**: Tokenized and lemmatized text to prepare for model training.
+   - **Model**: Built a Naive Bayes classifier to predict intents.
+   - **Deployment**: Deployed the model to predict user queries and return appropriate responses.
+
+---
+
+#### Additional Resources Used
+   - [Scikit-learn Documentation](https://scikit-learn.org)
+   - **Tutorial**: Building Chatbots with NLP and Machine Learning

+### FEATURES IN THE DATASET
+
+| Feature   | Description                                       |
+|-----------|---------------------------------------------------|
+| `intents` | User query categories like greetings, farewells.  |
+| `responses` | Predefined chatbot responses for each intent.   |
+
+---
+
+#### STEPS AND IMPLEMENTATION
+
+===  "step 1" 
+      Data Preprocessing
+    - Loaded the intents from CSV files.
+    - Cleaned data by removing duplicates and handling null values.
+
+
+
+===   "step 2"
+      Vectorization
+    - Used `TfidfVectorizer` to convert text into vectors.
+    - Split data into training and testing sets.
+
+
+===   "step 3"
+      Model Training
+    - Trained a Naive Bayes classifier on the preprocessed data.
+    - Saved the model for future use with `pickle`.
+    - Created an intent-response mapping.
+
+===  "step 4"
+      Prediction and Response Generation**
+    - The chatbot predicts the intent based on user input.
+    - Fetches and returns the appropriate response.
+
+=== "step 5" 
+      Testing
+    - Conducted live interaction tests with the chatbot.
+
+

+
+### Features Not Implemented Yet
+- Integration of a deep learning model (e.g., RNN or LSTM) for better context handling.

+## MODELS AND EVALUATION METRICS
+
+| Model            | Accuracy | Precision | Recall |
+|------------------|----------|-----------|--------|
+| Naive Bayes      | 92%      | 91%       | 90%    |
+

+
+### CONCLUSION
+
+??? "What Have You Learned?"
+      - Building a chatbot using NLP techniques can automate interactions and provide user-friendly interfaces for businesses.
+      -The Naive Bayes classifier is an effective yet simple model for intent prediction.
+
+---
+
+#### USE CASES
