TypeAid, Easy to Use

TypeAid receives as input an Ngram and predicts the Next Word

  • YOU WRITE: Your text
  • TYPEAID PREDICTS: Your Next Word

Example:

  • YOU WRITE: “I am a professor of political”
  • TYPEAID PREDICTS: “science”
  • YOUR NEW TEXT: “I am a professor of political science”

TypeAid Prediction Algorithm:

  1. Reads input text (news, twitter, or blogs) as a corpus
  2. Cleans the input text from symbols, punctuation, and more
  3. Generates words unigrams, bigrams, and trigrams from text
  4. Computes frequencies of unigrams, bigrams, and trigrams
  5. Computes the probability of a third word given the previous two words
  6. Generates a prediction model to be used in the App
