•Improves typing speed and user experience •Useful for assistive and predictive text systems •Demonstrates practical Natural Language Processing

Prediction Algorithm

The prediction engine uses N-gram language modeling with backoff.

How it works

  • Trigrams (3 words) → primary prediction
  • Bigrams (2 words) → fallback if trigram not found
  • Default word → used when no match exists

Key design choice

  • Frequency-based prediction for speed and simplicity

Using the Application

The app is designed for real-time interaction.

User Flow

  1. ✍️ Enter a short phrase
  2. ⚙️ The model analyzes recent words
  3. 🔮 The next word is predicted instantly

Example
Typing: How are
Prediction: you
