This page is a companion to the Workshop for select graduate students on the HathiTrust Research Center (HTRC) Portal 4/8/2014.

Preparation

  • Please do bring a laptop! If you have one, bring your own. If you do not have one, please feel free to
    Unknown macro: {menuicon}
    . Having a laptop will allow you to participate in the exercises and get the most out of class.
  • No special software will be needed. All exercises will be done through a Web browser, without any special plugins. However, Firefox is the browser that will work best for rendering results.
  • You will need to obtain credentials to log in. Please follow the steps on the
    Unknown macro: {menuicon}
    for getting started with the production portal.
  • Think about subject matter around which you might want to build a collection for analysis.  The production portal is limited to the 3M+ items that have been digitized by Google and are in the public domain.  These tend to be works that have been published before 1923, or are government documents, or items that are exceptions to various copyright restrictions. 

Agenda

The class is a guided exploration in the HTRC portal. We will explore the algorithms and use them to discover their capabilities, limitations, and various strategies for addressing those challenges. This allows us to explore the HTRC portal in specific, and grapple firsthand with basic issues encountered in computational analysis of text.

Support tips for exercises

  • Book mark this page for handy access. We will be referring to it at points in the workshop.

  • Log on to the
    Unknown macro: {menuicon}
    with your personal credentials.
    • Once signed in, click on "Algorithms" in the black navigational bar at the top of the page. Once you have done so, we will be ready to begin.

  • Worksets can be managed through the
    Unknown macro: {menuicon}
    . You can also access this by using the "Create Workset" link. Regardless of the avenue of entrance, you will have to log in a second time with the same credentials you are using in the Production Portal.
    • Worksets can be created through
      Unknown macro: {menuicon}
      of a CSV file containing Volume IDs
    • Unknown macro: {menuicon}
      MUST be created through upload.

  • I've made three collections for your use in this class. (You are not obligated to use these; you may want to use collections of your own in the exercises.)
    • ShakespeareComedies@MPaolillo - 58 dramas authored by William Shakespeare with MARC 655 field denoting "Tragedies."
    • ShakespeareTragedies@MPaolillo - 54 dramas authored by William Shakespeare with MARC 655 field denoting "Comedies."
    • ShakespearePlays@MPaolillo - A larger CSV formatted collection consisting of the contents of both of the other two collections.

  • Use
    Unknown macro: {menuicon}
    when referencing custom stop word lists. I can post lists relevant to your collections if you have them.

  • There may be a bug that prevents display of the results of the algorithm "Meandre_OpenNLP_Date_Entities_To_Simile". You can display locally by following this fix:
    • Download the date_entity_simile.html to your machine and save.
    • Open with a text editor and change this line 
      <script src="https://htrc2.pti.indiana.edu/HTRC-UI-Portal2/js/timeline-api.js" type="text/javascript"></script>
      to this line 
      <script src="http://api.simile-widgets.org/timeline/2.3.1/timeline-api.js" type="text/javascript"></script>
    • Save the html file and open with a web browser and the data should display. (Firefox works best with Simile.)
