Next Word Predictor

Using N-Gram Model with R Shiny

  • A simple predictive text application
  • Built using R Shiny and N-gram models
  • Goal: Predict the next word based on input phrase

Problem Statement

  • Typing assistance improves user experience
  • Predictive text is used in:
    • Messaging apps
    • Search engines
  • Our task:
    • Build a predictive model to guess the next word

Solution Overview

  • Built a Shiny app for real-time word prediction
  • Approach:
    • Use Bigram and Trigram models
    • Match user input and predict the next word
  • Features:
    • Simple interface
    • Real-time prediction

How It Works

  1. Collect sample text data
  2. Create bigrams & trigrams
  3. Prediction logic:
    • Match last two words → Trigram
    • Else match last one word → Bigram
  4. Output predicted word

Benefits & Future Scope

Benefits: - Lightweight and simple - Demonstrates NLP basics

Future Scope: - Use large datasets for better accuracy - Add deep learning models - Deploy on shinyapps.io for public use
