Coursera Data Science Capstone Project - Swiftkey Prediction Tool

What is the App and what does it do?

• Text prediction application
• User inputs at least one word
• App retrieves probable next words
• App displays a word cloud of probable choices, and suggests the next word that will be typed
• App also offers up to 5 more choices for the next word

How does the app work?

1. App draws on a corpus containg blog posts, twitter tweets, and news articles (all originally taken from the internet)
   
2. The app tries to match up to three words at a time to its known word combinations
   
3. If no match to three words, it tries to match the last two in the phrase; if no match to the last two it tries to match the very last word
4. If no matches at all, the app returns a list of the most probable single words in the corpus
5. If less than three words are entered: same rules as above as appropriate

How do I operate the App?

1. User types a word or phrase into the text box and presses 'Submit'
   
2. App shows the user what was entered, generates a word cloud, and offers next word choices
   
3. User can change input or press the “Clear” button to start over

A predictive algorithm for typing could have several uses:

• Make cellular phone use easier
• Help people with disabilities communicate better on personal computers
• Aid in Optical Character Recognition conversion programs
• Computer games and novelty electronics
