Introduction

ScatterPlot creates a scatter plot graph of terms, spaced by their variation from one another. Once you arrive to ScatterPlot, insert / upload your content and let the tool perform its analysis. You may hover over these dots and click on them for more information.

Ingredients

• A URL, some text, or a document, if available. Alternatively, you can use one of the corpora included with Voyeur.

Preloaded Corpora

• Novels of Jane Austen: http://voyeurtools.org/tool/ScatterPlot/?corpus=1308355966524.2331&stopList=stop.en.taporware.txt
• Novels of the Brontës: http://voyeurtools.org/tool/ScatterPlot/?corpus=1308356051583.4660&stopList=stop.en.taporware.txt
• Novels of George Eliot: http://voyeurtools.org/tool/ScatterPlot/?corpus=1308356746136.4470&stopList=stop.en.taporware.txt

Basic Steps

1. Go to http://voyeurtools.org/tool/ScatterPlot/ to load a document. Alternatively, use a preloaded corpus by clicking on one of the links above, and then skip ahead to step 4.
2. Provide a URL of a document you would like to visualize, or paste in some text. You can also upload your own document or open one of the included corpora by clicking the appropriate buttons.
3. Click "Reveal."
4. When you first load ScatterPlot, you will see a variety of terms plotted on a graph. If you hover over the terms, you will see their variation explained by each component on the x and y axis.
5. If you click on any of the terms, it will bring you to the Document KWICs tool for further analysis.
6. ScatterPlot offers options for changing the plot. The terms button allows you choose how many terms should be displayed. The dimensions button lets you switch between a two or three dimensional graph. Toggle labels simply removes or adds labels for the terms on the graph. You can also add terms by using the input box.
7. Click on the "gear" button at the top of the box and choose the Taporware stop word list from the dropdown menu, and then click "OK." Note how common words disappear from the results.

Suggested Activities

1. Add terms of interest to the diagram.
2. Play with the options at the top to view the data in different ways.

Discussion

It is important to remember that this is a beta release, which means that there will be bugs. Don’t trust everything you see without stopping to consider that it might be a mistake of some kind. As Stéfan says, “expect the unexpected.”

Description

A document describing Scatterplot is available here: http://entry.tapor.ca/?id=20

Who has worked on creating it

Voyeur is the product of Stéfan Sinclair and Geoffrey Rockwell.

Where to read about it

No papers have been published at this point, although the journal Literary and Linguistic Computing has published many articles that show the kind of work that is possible with a tool like Voyeur. Here is one example:

Fink, Peter. “The Evolution of Order in the Chapter Lengths of Trollope's Novels.” Literary & Linguistic Computing (21:3) Sep 2006, 275-282.
