COURSERA CAPSTONE PROJECT MILESTONE REPORT

Plans for creating the prediction algorithm and the Shiny app will also be discussed. The model will then be integrated into a shiny application that will provide a simple and intuitive front end for the ned user. This section describes the process to create a sample file training dataset from the three raw data files. This will create a unigram Dataframe, which we will then manipulate so we can chart the frequencies using ggplot. These algorithms will be based on frequency.

Calculate Frequencies of N-Grams Step 7: We will require the following helper functions in order to prepare our corpus. In this project, we are interested in the three forms of data in English. Plans for creating the prediction algorithm and the Shiny app will also be discussed. This report is an exploratory analysis of the training data supplied for the capstone project. I made a wordcloud.

It is assumed that the data has been downloaded, unzipped and placed into the active R directory, maintaining the folder structure.

Plans for creating the prediction algorithm and the Shiny app will also be discussed. Rmd, which can be found in my GitHub repository https: Does including it in the training proejct contribute to more accurate predictions?

The main parts are loading and cleaning the data as well as use NLM Natural Language Processing applications in R s a first step toward building a predictive model.

Overview of the sample data Step 4: Courxera overall objective is to help users complete sentences by analyzing the words they have entered and predicating the next word.

Alternative graph to see quicly the main word. Introduction This milestone report is based on exploratory data analysis of the SwifKey data provided in the courssera of the Coursera Data Science Capstone.

Introduction the milestone report for week 2 in the Exploratory Analysis section is from the Coursera Data Science Capstone project. Rda” ggplot head trigram.

Raw Data Summary Below you can find a summary of the three input files. We use readLines to load blogs and twitter, but we load news in binomial mode as it contains special characters.

Now that we have our corpus item, we need to clean it. The following task have been accomplished: I made a wordcloud. The cleaning procedure performed the following actions: In addition to loading and cleaning the data, the aim here is to make use of the NLP packages for R to tokenize n-grams as a first step toward testing a Markov model for prediction.

This command can be used for obtaining text reporf and is available on every Unix based system. To summarize the all info until now, I seleted an small subset of each data and compared with the main files. Text documents are provided in English, German, Finnish and Russian and they come in three different forms: 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. If none is found, then the 3-gram model is used, and so forth.

These algorithms will be based on frequency. Next, we need to load the data into R so we can start manipulating.

After reducing the size of each data set that were loaded sampled data is used to create a corpus, and following clean up steps are performed. 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. We will require the following helper functions in order to prepare our corpus.

This will create a unigram Dataframe, which we will then manipulate so we can chart the frequencies using ggplot.

Some of the code is hidden to preserve space, but cappstone be accessed by looking at the Raw. Here milesyone list the most common unigrams, bigrams, and trigrams. Each of these N-grams is transformed into a two column dataframe containing the following columns: If you are running windows, you can download the GnuWin32 utility set from http: Build basic n-gram model. Before moving to the next step, we will save the corpus in a text file so we have it intact for future reference.
