TypeAhead Word Predictor

TypeAhead is a software tool that predicts the probable word that will be typed by the user.

• Utilizes a Machine Learning model for prediction
• Very responsive to end user (takes less than 100 milliseconds typically)
• Good accuracy
• Developer friendly API available!

All of the above results is saving a lot of time for the end users!

• N-Gram modeling as described by Daniel Jurafsky and James H. Martin in their paper Speech and Language Processing
• Unigram, Bigram, Trigram and Quadgram models built using training data based on twitter, blogs and news
• Memory footprint for N-Grams optimized
• Further details on the model can be found at http://rpubs.com/mgravi7/WordPredict

Accuracy

• Using completed words, accuracy is 11% for the top word.
• Accuracy is 20% when examining the top five predicted words.
• Using in-progress words, accuracy is 45% for the top word.
• Accuracy is 60% when examining the top five prdicted words.

Performance
