I utilized the benchmark code by Jan to test the performance of the next term prediction app. You can try out the Text Prediction App on the Shiny server. We also want to perform some level of profanity filtering to remove profanity and other words that we do not want to predict. An excerpt of text cleaning and other transformations: Removal of all non-alphanumeric characters to bypass prevailing encoding issues.

Data Preparation From our data processing we noticed the data sets are very big. Btw thanks for the RT. Post A Comment Cancel Reply. Possibly removing the list of English stop words is not necessary for building this SmartKey product, but it is a reasonable starting point to remove and see. Flagging numbers to eventually remove them as we want to predict terms. There is a lot of information in those documents which is not particularly useful for text mining. In this capstone, we will work on building predictive text models which could present three options for what the next word might be when people type on their mobile devices.

Data Exploration Now that we have the data in R, we will explore our data sets. As a projject step, I created 4 n-gram tables: Executive Summary Coursera and SwiftKey have partnered to create this capstone project as the final project for the Data Scientist Specilization from Coursera. Removal of any Internet related content hyperlinks, emails, retweets. Speed will be important as we move to the shiny application.

The prediction model is based on three different sources swifttkey text blogs, news, tweets.

Flagging numbers to eventually remove them as we want to predict terms. First we convert all of the text to lowercase and then remove punctuation, numbers swiftkeg common English stopwords. We notice three different distinct text files all in English language. Love to see you. Data Processing After we load libraries our first step is to get the data set from the Coursera website. We are given datasets for training purposes, which can be downloaded from this link.

After we load libraries our first step is to get the data set from the Coursera website. Your heart will beat more rapidly and you’ll smile for no reason.

The goal of this capstone project is for the student to learn the basics of Natural Language Processing NLP and to show that the student can explore a new data type, quickly get up to speed on a new application, and implement a useful model in a reasonable period of time. But typing on mobile devices becomes a serious pain for many cases.

We must clean the data set. Finally, we can then visualize our aggregated sample data set using plots and wordcloud.

SwiftKey Capstone Project – Milestone Report

Cleaning the data is a critical step for ngram and tokenization process. The ultimate goal for this capstone project is to predict the next word based on a secuence of words typed as input. Our second step is to load the date set into R.

The pproject is extremely intuitive. My final model performs as follows:. My final model performs as follows: In this capstone, we will work on building predictive text models which could present three options for what the next word might pgoject when people type on their mobile devices.

RPubs – Coursera Capstone Project- Swiftkey

The objective of the capstone project was to 1 build a model that predicts the next term in a sequence of words, and to 2 encapsulate the result in an appropriate user interface using Calstone.

The final app offers a variety of benefits to its users: Conversion of text to lower case and removal of any unnecessary whitespaces.

It allows native German-speakers to use the app as well experimental. Therefore we will create a smaller sample for each file and aggregate all data into a new file. Btw thanks for the RT. We assume each word is spereated with a whitespace in each sentence, and leverage strsplit function to split the line and count the number of words in each file.

The model recognizes capztone of sentences based on. By the usage of the tokenizer function for the n-grams a distribution of the following top 10 words and word combinations can be inspected. Nowadays, people are spending great amount of time on mobile devices.
