CAPSTONE PROJECT SWIFTKEY

Flagging end of sentences to avoid that the app makes predictions across sentence boundaries. To achieve this, we need to evaluate n-grams sequence of n words and the frequency in the training data. From our data processing we noticed the data sets are very big. We must clean the data set. 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.

Love to see you. We must clean the data set. The project includes but is not limited too: Btw thanks for the RT. It offers its users up to 3 next best terms.

SwiftKey Capstone Project – Milestone Report

The final app offers a variety of benefits to its users: For the subsequent model building process, I drew a random sample of text and began the data preparation. Data Exploration Now that we have the data in R, we will explore our data sets. We are given datasets for training purposes, which can be downloaded from this link. The ultimate goal for this capstone project is to predict the next word based on a secuence of words typed as input. Removal of all non-alphanumeric characters to bypass prevailing encoding issues.

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.

Removal of any Internet related content hyperlinks, emails, retweets. Data Preparation From our data processing we noticed the data sets are very big.

Btw thanks for the RT. 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 Shiny.

Speed will be important as we move to the shiny application. 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 prject the Coursera website.

Post A Comment Cancel Reply. Now that the data is cleaned, we can visualize our data to better understand what we are working with.

The project includes but is not limited too: But typing on mobile devices becomes a serious pain for many cases. Today is a great … day. Coursera and SwiftKey have partnered to create this capstone project as the final project for the Data Scientist Specilization from Coursera.

Flagging numbers to eventually remove them as we want to predict terms. Your heart will beat more rapidly and you’ll smile for no reason.

There is a lot of information in those documents which is not particularly useful for text mining. We notice three different distinct text files all in English language.

Conversion of text to lower case and removal of any unnecessary whitespaces. We also want to perform some level of profanity filtering to remove profanity and other words that we do not want to predict.

Our second step is to load the date set into R. Data Visualization Now that the data is cleaned, we can visualize our data to better understand what sdiftkey are working with. Milestone Conclusions Using the raw data sets for data exploration took a significant amount of processing time.

Andre Obereigner | A Text Prediction App in Collaboration with Coursera & SwiftKey

Less data has its capsgone, I assume it will decrease the accuracy of the prediction. To achieve this, we need to evaluate n-grams sequence of n words and the frequency in the training data. To acheive this goal, we use a bad words dataset from Sdiftkey as a reference point for bad words removing.

Love to see you. 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.

We must clean the data set.
