  1. Computer assisted content analysis How to qualitatively analyze medium to

    large corpus of texts Alberto Lusoli, Simon Fraser University. School of Communication
  2. Automated coding Computer-assisted coding Broad textual analysis

  3. Computer based analysis Suitable for quantitative studies High reliability Validity

    might be limited
  4. Automated analysis in Nvivo Sentiment Autocoding

  5. Mac Users: Please wait...

  6. Using software to facilitate the human coding of large corpus

    of texts
  7. Content analysis with Nvivo An example with a large dataset

    of tweets collected automatically (more on this next later) Download the project here: http://bit.ly/ca-nvivo-pc http://bit.ly/ca-nvivo-mac

  9. How to qualitatively analyze a dataset? Just like any other

    corpus of text. By coding it (inductively or deductively).

  16. Ncapture for Nvivo Quick&Dirty application for collecting tweets, FB posts,

    youtube comments and webpages Install the Chrome Extension
  17. Ncapture for Nvivo When done, you should see a new

    icon on your extensions list (click the More Option if it does not appear in the toolbar)
  18. Supported data Webpages (PDF) Twitter tweets (hashtags, individual profiles tweets)

    FB pages posts and comments Youtube comments (PC version only)
  19. Capturing a page Go to the page you want to

    capture Click on the Ncapture Select Webpage as PDF Check the progress in the Chrome Capture page In Nvivo, go to Sources > internal And click Import from Ncapture If the captured page does not appear in the list, check the Download folder
  20. Capturing Tweets Login on yourTwitter account Search for something or

    visit a Twitter profile page Click the Ncapture Icon Select “Tweets as Dataset” Authorize the App Check progress page (stop the collection as some point..) Go to Nvivo and, as done previously, import the Dataset as an Internal Source
  21. Capturing FB posts Go to a Facebook page (while being

    logged in) and follow the same steps done for Twitter. Collect as Dataset Authorize the app Let NCapture collect data Import the Dataset as an Internal source in Nvivo Can you think of privacy and confidentiality issues?
  22. Gephi integration SNA tool. You can use tweet networks Need

    training? Research Common!
  23. Web archiving Search the archive Search keyword on Wayback machine

    Search website on Wayback machine
  24. Build your own archive Webrecorder.io Archive webpages Archive infinite scroll

    pages Download archives and visualize them with Webrecorder Player http://rhizome.org/software/
