Project Overview

Objective:
Develop a web-based app that predicts the next word in a sentence, simulating smart keyboard or chatbot behavior.

  • Product:
    A Shiny app where users enter a phrase and receive a next-word prediction instantly.

  • Use Case:
    Streamline communication in digital platforms and showcase advanced language modeling skills.

The Prediction Algorithm

Model:
Utilizes a Stupid Backoff n-gram algorithm trained on Twitter, blog, and news corpora.

  • How It Works:
    Cleans and tokenizes input; analyzes up to four previous words to determine the statistically most probable next word using n-gram frequency tables.

  • Strengths:
    Fast, lightweight, and robust for varied real-world English input.

App Demo & Instructions

  • Features:
    • Accessible via Shinyapps.io (live link).
    • Simple text input box for phrase entry.
    • “Submit” button to generate prediction.
  • Instructions:
    1. Visit the app’s link.
    2. Enter a partial phrase (e.g., “The future of AI is”).
    3. Press submit; the predicted next word appears instantly.
  • Tested With:
    Five authentic phrases from social media/news—returns a prediction for each.

User Experience

  • Interface:
    Intuitive, clean, and responsive — requires no technical background.

  • Performance:
    Predicts rapidly with minimal delay, even for complex or unusual phrases.

  • Reliability:
    Handles slang, typos, and incomplete sentences with real-world accuracy.

Novelty, Business Value & Closing

  • Innovation:
    Combines speed and accuracy with a scalable backend, ready for real deployment.

  • Applications:
    Chatbots, smart keyboards, assistive tech, automated writing.

  • Business Value:
    Enhances user engagement, demonstrates advanced NLP, and enables further product development.
