Problem Statement

Predictive Text Challenge

  • Users type millions of messages daily.
  • Faster typing improves productivity.
  • Intelligent prediction reduces keystrokes.
  • Goal: Build a next-word prediction system using NLP.

Business Value

  • Better user experience
  • Faster communication
  • Increased engagement

Algorithm

N-Gram Language Model

The prediction engine uses:

  • Data cleaning
  • Tokenization
  • Unigrams
  • Bigrams
  • Trigrams

Workflow:

  1. User enters text
  2. Last words are extracted
  3. Matching n-grams are searched
  4. Most probable next word is returned

Application

Shiny Web App

Features:

  • Simple interface
  • Real-time prediction
  • Fast response
  • Easy to use

User enters a phrase and clicks Predict.

The application immediately displays the predicted next word.
