CodeAlpha Internship Projects

NLP projects completed as part of the CodeAlpha internship program.

📁 Projects

1. 🤖 FAQ Chatbot (chatbot_for_faqs.ipynb)

A rule-based chatbot that answers questions about AI and machine learning concepts using TF-IDF vectorization and cosine similarity for intent matching.

How it works:

• FAQ knowledge base defined as key-value pairs
• User query is vectorized with TF-IDF
• Cosine similarity finds the best matching question
• Returns the corresponding answer (or fallback if confidence < 0.3)

Stack: Python, scikit-learn, NLTK

2. 🌐 Language Translation Tool (language_translation_tool.ipynb)

An interactive translation tool supporting multiple languages using the deep-translator library (Google Translate API wrapper).

How it works:

• User inputs source language, target language, and text
• GoogleTranslator handles the translation
• Clean CLI interface with error handling

Stack: Python, deep-translator

🧰 Technologies Used

• Python 3
• scikit-learn — TF-IDF, cosine similarity
• NLTK — Natural language toolkit
• deep-translator — Google Translate wrapper

🚀 How to Run

1. Open either notebook in Google Colab
2. Run all cells — dependencies install automatically
3. Interact via the input prompts
