COURSERA CAPSTONE PROJECT MILESTONE REPORT

In this case, we use the US English versions. In order to be able to clean and manipulate our data, we will create a corpus, which will consist of the three sample text files. There are three text files: The first step in the process is to read in the three input files. Our target files are: We use readLines to load blogs and twitter, but we load news in binomial mode as it contains special characters.

The numbers have been calculated by using the wc command. This report is an exploratory analysis of the training data supplied for the capstone project. Introduction the milestone report for week 2 in the Exploratory Analysis section is from the Coursera Data Science Capstone project. This section describes the process to create a sample file training dataset from the three raw data files. The main goal of the capstone project is the application based on a predictive text model using explain the Explortory Data Analysis and building an algorithm. The first analysis we will perform is a unigram analysis.

mileetone The main goal of the capstone project is the application based on a predictive text model using explain the Explortory Data Analysis and building an algorithm. In this case, we created four different N-grams as follows: I made a wordcloud. Removal of profanity will be a consideration for the predicted text. Essentially, we flip a coin to decide which lines we should include.

Rmd, which can be found in my GitHub repository https: Future Work My next steps will be: Sample Summary A summary for the sample can be seen on the table below.

These algorithms will be based on frequency.

The data can be found at the following link on Coursera: Some of the code is hidden to preserve space, but can be accessed by looking at the Raw.

The Milestonf representation of a text lists all N-tuples of words that appear. Alternative graph to see quicly the main word.

The overall objective is to help users complete sentences by analyzing the words they have entered and predicating the next word. A possible method of prediction is capatone use the 4-gram model to find the most likely next word first. Rda” ggplot head bigram. Another assumption is that the command wc is available in the target system. For the Shiny app, the plan is to create an app with a simple interface where the user can enter a string of text.

This milestone report is based on exploratory data analysis of the SwifKey data provided in the context of the Coursera Data Science Capstone.

Unigram Analysis The first analysis we will perform is a unigram analysis.

Coursera Capstone Project – Milestone Report

The goal of the Data Science Capstone Project is to use the skills acquired in the specialization in creating an application based on a predictive model for text.

Clean up the corpus by removing special characters, punctuation, numbers etc. This will show us which words are the most frequent and what their frequency is.

My next steps will be: Briefly, the application works with a worth ant then it will try to predict the next word. For now, we used this tool to explore certain patters in the data, including most notably the highest frequency 1,2,3 and 4 length word patterns.

While the strategy for modeling and prediction has not been finalized, the n-gram model with a frequency look-up table might be used based on the analysis above. Then we will download the text files used in this ptoject, those files can be downloaded from the following link: To do that we will use the google badwords database. This report is a milestone report of the capstone project introduced by Johns Hopkins University through Coursera.

Introduction This milestone report is based on exploratory data analysis of the SwifKey data provided in the capsone of the Coursera Data Science Capstone.

I will build a UI of the Shiny app and this will consist of a text input box that will allow a user to enter a word or phrase. Next, we need to load the data into R so we can start manipulating. Executive summary This milestone report for the Data Science Capstone project provides a summary of data preprocessing and exploratory data analysis pfoject the data sets provided. To get a sense of what the data looks like, I summerized the main information from each of the 3 datasets Blog, News and Twitter.

Our prediction model will then give a list of suggested words to update the next word.
