• How does it work
  
• Source data
  
• Algorithm and relevant documentation
  
• Thank yous

Link to the Shiny App

https://coursephd.shinyapps.io/WordPredictApp/

How does it work - Inputs are as follows

Populate any word in English in the “Input” box and hit enter
Default prediction parameter is set to a single word
The user can choose to set the value from 1 to 5 In the “Next word” box predicted words would get populated

Source data: Capstone Dataset

R packages:
- Shiny
- tm (text mining package)
- Rweka
- stringr

Algorithm and relevant documentation

• Natural language processing Wikipedia page
  
• Text mining infrastucture in R
  
• CRAN Task View: Natural Language Processing
  
• n gram algorithms

My algorithm utilizes a group of bigram, trigram and n-gram dataframes created using the packages mentioned before

Thank yous

I would like to thank all the professors, fellow students, known as well as unknowns who helped on queries.

This is a very good course, please continue the good work.
