Next Word Prediction App

A Shiny App powered by Bigram Prediction Algorithm

  • Built in R & Shiny
  • Predicts the next word based on a phrase
  • Deployable on shinyapps.io

Problem Statement

  • Typing is slow and repetitive in many applications.
  • Predictive text can help users save time by suggesting the next word.
  • Our goal:
    • Build a lightweight Shiny app to predict the next word in real-time.
    • Create a prototype that can be scaled to real-world applications. ## Prediction Algorithm

Bigram Model (Statistical Language Model)

  1. Training:
    • Break sentences into word pairs (bigrams).
    • Count how often each pair occurs.
  2. Prediction:
    • Take the last word from the user’s phrase.
    • Suggest the most frequent word that follows in the training data.

Example:

Input: “I am” → Bigram Table: (“am”, “learning” → 5 times, “am”, “working” → 3 times) Predicted Word: “learning”

App Description & Usage

  • How it Works:
    1. Enter a phrase (e.g., “I am”).
    2. Click “Predict Next Word”.
    3. The app shows the predicted next word.
  • User Interface:
    • Simple input box + one-click prediction.
    • Fast and lightweight.
  • Experience:
    • Easy to use even for non-technical users.
    • Real-time response, feels like using mobile keyboard prediction.

Business Impact & Future Scope

  • Applications:
    • Smart keyboards, chatbots, auto-complete in emails.
    • Writing assistants & customer support bots.
  • Future Enhancements:
    • Use Trigram / Deep Learning (LSTM, Transformers) for better accuracy.
    • Train on real-world large datasets.
  • Why It’s Novel?
    • Lightweight, deployable in a browser.
    • Can be expanded to a full predictive typing system.

Would you invest?Yes, because predictive text is a billion-dollar market!
