Task 1. Visualizing Word Frequency. Looking at the frequency of occurrence of each word can give you an overall sense of a document. You will use your article to create a word cloud to visualize frequency and understand how stop words affect word frequency analysis. We will use
WordClouds
for this.
Task 2. Taking a deeper look at word frequency and occurrence. For the second text document we will use
Voyant Tools
to explore other visualization methods as well as look at word correlations. You will be adding screenshots and answering the questions on the template.Steps for finding an article:
1. go on gallileo.
2. enter a topic about sports that interests you in the search box. click the ‘Full text only’ box. hit search.
3. Find a Scholarly article between 2-4 pages long and download the pdf full text
steps for task 1:
Open the following website: WordClouds
2. Click the Wizard to get a walk through for how to use the software. To create a Word Cloud, you will upload your pdf. Click File -> New Word Cloud -> Blank Canvas. Click Word List -> Extract Words from pdf document and select the document you downloaded from Galileo. Leave all settings alone and click apply. It will be set to ‘Ignore stop words’ and ‘Ignore word case’ by default.
3. Personalize your Word Cloud by using different Theme, Shape, Gap, Font or other options. Once you are happy with the look, take a screenshot and add it to the template in the first section for ‘with stop words removed.’
4. Stop Words are small, common connector words that are frequent in English, but don’t usually convey much meaning. Let’s see how the word cloud changes if we remove these from the results. We need to recreate the word cloud. Click Word List -> Extract Words from pdf document and select the document you downloaded from Galileo. This time, uncheck the box for ‘Ignore stop words’ and click apply. The word cloud will change (if it doesn’t you’ll need to repeat the steps to make sure you didn’t use the wrong setting). Use the same personalization as you used for the first word cloud, take a screenshot and add it to the template in the second section for ‘without stop words removed.’
