CAPSTONE PROJECT SWIFTKEY

We also want to perform some level of profanity filtering to remove profanity and other words that we do not want to predict. The user can immediately begin to enter text , see and choose from up to 3 next terms and simply click and add them to the existing message. It offers its users up to 3 next best terms. There is a lot of information in those documents which is not particularly useful for text mining. Conversion of text to lower case and removal of any unnecessary whitespaces.

An excerpt of text cleaning and other transformations: Clean means alphabetical letters changed to lower case, remove whitespace and removing punctuation to name a few. Btw thanks for the RT. Executive Summary Coursera and SwiftKey have partnered to create this capstone project as the final project for the Data Scientist Specilization from Coursera. Your heart will beat more rapidly and you’ll smile for no reason. As a next step, I created 4 n-gram tables: We notice three different distinct text files all in English language.

Data Exploration Now that we have the data in R, we will explore our data sets. Coursera and SwiftKey have partnered to create this capstone project as the final project for the Data Scientist Specilization from Coursera.

The model recognizes end swiftke sentences based on.

We also want to perform some level of profanity filtering to remove profanity and other words that we do not want to predict. The app is extremely intuitive. Flagging numbers to eventually remove them as we want to predict terms. It offers its users up to 3 next cpastone terms.

Data Processing After we load libraries our first step is to get the data set from the Coursera website. After we load libraries our first step is to get the data set from the Coursera website. Removal of any Internet related content hyperlinks, emails, retweets.

SwiftKey Capstone Project – Milestone Report

You can try out the Text Prediction App on the Shiny server. Once a cleaned set of text source was available in form of n-gram tables, I began to implement capsgone test a variety features. Cleaning the data is a critical step for ngram and tokenization process.

My final model performs as follows:.

The final app offers a variety of benefits to its users: Therefore we will create a smaller sample for each file and aggregate all data into a new file. Love to see you.

Cxpstone that the data is cleaned, we can visualize our data to better understand what we are working with. Btw thanks for the RT.

To achieve this, we need to evaluate n-grams sequence of n words and the frequency in the training data. As a next 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. But typing on mobile devices becomes a serious pain for many cases.

Been way, way too long. 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. Nowadays, people are spending great amount of time on mobile devices. So before proceeding any further, we clean things up a bit.

Learned the hard way, but I ended up creating a much smaller sample of the raw data with less information to decrease processing time. Data Preparation From our data processing we noticed the data prkject are very big. 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.

We notice three different distinct text files all in English language. An excerpt of text cleaning and other transformations: I utilized the benchmark code by Jan to test the performance of the next term prediction app. The ultimate goal for this capstone project is to predict the next word based on a secuence of words typed as input. The user can immediately begin to enter textsee and choose from up to 3 next terms and simply click and add them to the existing pfoject.

Removal of all non-alphanumeric characters to bypass prevailing encoding issues.
