Introduction

• This is my final project for the Data Science Capstone.
• It predicts the next word using a Shiny app.
• Built using basic pattern-matching and NLP logic.

Data & Preprocessing

• Manually created a set of sample phrases and rules.
• Lowercased and trimmed input.
• Pattern matching used to find likely next word.

Algorithm

• Used grepl() to match common phrases.
• If a known phrase is found, return a next word.
• Else, return “the” as a default.
• Fast and lightweight logic.

Shiny App

• User enters a phrase in a textbox.
• Clicks “Predict” → app shows next word.
• Open the app here

Conclusion

• Simple and fast app using R and Shiny.
• Future work: real n-gram models, larger datasets.
• Clean UI, good user experience.
