The objective of my App is to predict the most probable following word from an input text given by the user. The dataset used to train the model includes twitter, news and blogs from HC Corpora. The first steps in this project were the cleaning and sampling of the total data collected. It was developed using some functions from the tm package and Natural Language Processing techniques (N-grams). The implemented algorithm corresponds to Katz Backoff algorithm to predict the next word. Prove it! My app
