Smart keyboard makes it easier for people to type on their mobile devices. One cornerstone of smart keyboard is predictive text models.

The goal here is to build first simple model for the relationship between words. This is the first step in building a predictive text mining application. Tasks to accomplish: * Build basic n-gram model - using the exploratory analysis, build a basic n-gram model for predicting the next word based on the previous 1, 2, or 3 words. * Build a model to handle unseen n-grams - in some cases people will want to type a combination of words that does not appear in the corpora. Build a model to handle cases where a particular n-gram isn't observed.

The Storm Data from the NOAA has been used to answer following questions: Across the United States, which types of events (as indicated in the EVTYPE variable) are most harmful with respect to population health? Across the United States, which types of events have the greatest economic consequences?
