Hesburgh Libraries Archives

I am curious to learn, "What sorts of things are in the Hesburgh Libraries Archives?"

To answer this question, I first used a program called wget to downloaded all of the Encoded Archival Description (EAD) files from the Archives's website. This generated a cache of 1,200 XML files. I then extracted the titles, biographical histories, and scope notes of 258 of these items. They represent Catholic manuscript collections and collections termed 'Notre Dame-related' (professor and alum personal papers, materials related to Notre Dame history, et cetera). These items did not include closed University records.

The resulting collection of descriptions is about 2.2 million words long. (For comparison's sake, the Bible is about .8 million words long.) And while the average size of the descriptions is 8,500 words long (the size of a long journal article), two descriptions are off the charts in terms of length; each of the Notre Dame Presidents' Letters (1856-1906) and the University Photographer collections are .25 million words long. In other words, the description of these two collections make up about 25% of the entire descriptions in this analysis. Put yet another way, the sizes of the collections are skewed, as the following two charts illustrate:

More to my question -- What sorts of things are in the collection? -- rudimentary unigram, bigram, and keywords analysis points to photographs, sports (namely, football and basketball) as well as the names of men. Given the titles of the predominate collections, this ought not be surprising. Again, charts are illustrative:


unigrams

bigrams


statistically significant keywords

For additional descriptive statistic sorts of illustrations, see the automatically generated page descriping this data set.

Topic modeling is a popular machine learning technique used to enumerate latent themes is a corpus. The application of topic modeling to this corpus results in a seemingly more balanced view of the collection. For example, if I model the corpus for a single word used to describe the whole, then the result is still sports-related, "football". But if I model the corpus for four topics, and each topic is elaborated upon with four words, then the results are more nuanced:

       labels   weights                             features
          john  0.49117          john tape degree interview 
     portraits  0.17081       portraits hall photos student 
      football  0.07759  football player basketball coaches 
           jwc  0.07554             jwc president john paul

Modeling the corpus on sixteen words results in the following themes and proportions; now, the results are not so much about sports, but sports do exist:

        labels  weights                                           features

Hoping for an elaboration, I created a network diagram from the top four topic words and their bigrams. The following illustrates the results, and my take-away is, "The things in the collection are more about the University as an institution and its people and less about the University's academics":

In conclusion, I was not able to answer my origainal question; I do not know what sorts of things are in the collection. On the other hand, I believe I do have a handle on what the things are about. They are about the University of Notre Dame. Duh!?

P.S. It would be interesting to learn who or what "jwc" is. Concordancing for jwc was not very telling, and the following results are typical:

  j.e. grove to am; juan a. garcia jr. to jwc ; charles a. gorman to jwc; julia a. gal
  garcia jr. to jwc; charles a. gorman to jwc ; julia a. galvin to jwc; rev. p.j. clan

   jwc; jwc to louis fox; john gerrard to jwc ; w.a. sutherland to [jwc]; jwc to peter

According to one of my colleagues, jwc might very well be John W. Cavanaugh.
