Embedded Voyeur

Navigating to webpage

1. Navigate to a site that has Voyeur embedded. For example, we have a dummy wordpress site at http://coreyslavnik.com/wordpress/.

2. In the right hand corner there is a voyeur panel. The default is set to Cirrus where it shows the frequency of words on the page in a cloud form.

3. In the top right hand corner of the Voyeur panel there are three buttons: Options, Export, and Help.

- Options

By clicking the Options button you can set certain tool options. In Cirrus and Summary you can set the 'Stop Words List' to either 'none', 'Taporware(English)' or 'Véronis (French)'. In Frequency Grid you can set the 'Stop Words List' to either 'Taporware(English)' or 'Véronis (French)', choose a Comparison Corpus and set a Minimum Z-Score. In Bubbles and Reader there are no options.

- Export

By clicking the Export button a popup window appears telling you that there isn't enough room to display the window in the current space. By clicking 'OK', a new window will be opened showing a full screen version of the tool. By clicking 'Cancel' you remain on the page embedded with Voyeur.

- Help

By clicking the Help button a popup window appears telling you that there isn't enough room to display the window in the current space. By clicking 'OK', a new window will be opened showing a full screen version of the tool. By clicking the Help button once more in the full screen version a window appears giving you a summary of what the tool does.

4. Clicking on the 'Reveal' button below Voyeur brings up a menu where you can specify filters or change the tool being displayed.

5. In the popup menu you can filter by author, category, tags, or date. This is done by checking the box beside the desired filter then clicking the submit button at the bottom of the menu. Once you click submit, the voyeur panel changes to represent your filter or tool choice.

In the Reveal popup you can also change tool. By changing the tool, Voyeur displays different text analysis tools. Here is help on the different tools.

Bubbles

- Words appear in the screen as bubbles. The larger the word is, the more frequent it appears on the page.

Cirrus

- Cirrus is a word cloud where the most frequent word in the document are displayed. The larger the word is, the more frequent it appears on the page. By hovering over a word a number appears telling you how many times that word appears in the page. By clicking a word, Voyeur opens in a new window to give you more information on the frequency of the word.

Frequency Grid

- This tool shows overall word frequencies for the entire corpus as well as information about how word frequencies are spread out over documents within the corpus. Hover over column headers and buttons for more information. This table shows the frequency of the words on the page in descending order of frequency. By scrolling to the right, there is a trend graph that shows where in the document the word occurs.

Links

- This tool finds collocates for words and displays links between them using a force directed graph. This is like a web where all words are a different color depending on which post there are the most hits(places where the word appears). The bigger the word is, the more frequent it is on the page. When you hover over a word it tells you which post it occurs in and how many links and hits(times the word occurs in the post). Double-click a word to find its collocates; right-click a word to remove it, or make it "sticky"; right-click an empty area to save the graph to an image file.

Reader

- With the reader all posts are color coded on the left hand side of Voyeur. By navigating through the left side bar you can read all the posts one by one.

Summary

- This gives you a summary of the entire document. It gives you the longest and shortest document, highest vocabulary density, most frequent words, notable peaks in frequency and distinctive words. Some of these categories have a trend graph showing where in the document the word occurs.
