By the end of this project, you will learn about the concept of document similarity in textual analysis in R. You will know how to load and pre-process a data set of text documents by converting the data set into a corpus and document feature matrix. You will know how to calculate the cosine similarity between documents and explore and plot the output of your calculation.

Skills you will develop

  • cosine similarity

  • Text Analysis

  • Document Similarity

  • Data Visualization (DataViz)

  • Text Corpus

Learn step-by-step

In a video that plays in a split-screen with your work area, your instructor will walk you through these steps:

  1. Load textual data into R and turn it into a corpus object and understand the concept of calculating document similarity in textual analysis

  2. Extract meta-data from text document filenames and subset the data frame to exclude unwanted data

  3. Tokenize and clean the dataset and convert the data into a document feature matrix

  4. Calculate cosine similarity across documents and plot the output
