🧠 Attention - Sentiment Analysis with AI

Attention is an advanced sentiment analysis tool designed to determine the emotional tone of textual input, leveraging cutting-edge natural language processing (NLP) techniques.

🔍 What Does This Project Do?

The Attention project classifies input text into positive, negative, or neutral sentiment categories. This is achieved through the integration of BERT, a state-of-the-art transformer-based language model developed by Google.

Key features of the project include:

• Transformer Architecture: Powered by BERT, which uses self-attention mechanisms to capture contextual relationships in text. 🔗
• Pre-trained Model Utilization: Fine-tuned on sentiment analysis datasets for high accuracy in predicting sentiment. 🎯
• Natural Language Understanding: Handles complex sentence structures and subtle linguistic nuances. 🌐

🛠️ Technologies Used

This project employs a robust combination of technologies and frameworks, including:

1. BERT: (Bidirectional Encoder Representations from Transformers)

   • A transformer-based model that processes text bidirectionally, capturing both past and future context in sentences.
   • Fine-tuned on sentiment-specific data for enhanced performance.

2. Hugging Face Transformers Library:

   • Provides pre-trained models and pipelines for seamless integration with NLP tasks.

3. Natural Language Toolkit (NLTK):

   • Used for preprocessing steps, such as tokenization, stemming, and stop-word removal.

4. Pandas and NumPy:

   • Essential for data manipulation and analysis during training and testing phases.

5. Scikit-learn:

   • Supports evaluation metrics like accuracy, precision, and recall.

🔧 How It Works

1. Preprocessing: Input text is cleaned and tokenized, ensuring compatibility with the BERT model.
2. Encoding: Text is converted into numerical embeddings using BERT's tokenizer.
3. Prediction: Sentiment is classified using a fine-tuned BERT model, producing one of three categories: positive, negative, or neutral.
4. Evaluation: Results are validated using datasets like IMDb or custom sentiment datasets, ensuring precision.
