Interactive maps from the ACH 2019 Conference August 5, 2019August 5, 2019 jshanahan Leave a comment Our most recent mapping experiment explored whether CPL programming influences circulation for the Chicago-themed “One Book” selections in our dataset. If so, to what degree? What correlations, if any, could be inferred when mapping CPL events and OBOC checkouts for the three Chicago-themed books, The Adventures of Augie March, Warmth of Other Suns, and The Third Coast? Our hunch was that events have a considerable impact on the number of checkouts; however, the data reveals different trends. Ana and Mihaela made useful visualizations. Because at the Pittsburgh ACH conference… Read more
What do CPL branch libraries have in common? February 12, 2019February 12, 2019 jshanahan Leave a comment As we finish our omnibus white paper on the project, some maps and visualizations have been augmented to include the latest book seasons and recolored to show the branch clusters and checkouts per book. We’ve also excerpted some of the explanation. In order to create Figure C, we performed unsupervised clustering of the branches based on their demographic characteristics. We used the Partitioning Around Medioids (PAM) algorithm [Kaufman 1990], which is known to be more robust to noise and outliers compared to the more widely-used k-means algorithm. PAM is more computationally-intensive… Read more
