Visualizing Solr Search Results with D3.js for User-Friendly Navigation of Large Results Sets

Julia Bauder, Grinnell College Libraries

As the corpus of articles, books, and other resources searched by discovery systems continues to get bigger, searchers are more and more frequently confronted with unmanageably large numbers of results. How can we help users make sense of 10,000 hits and find the ones they actually want? Facets help, but making sense of a gigantic sidebar of facets is not an easy task for users, either. During this talk, I will explain how we will soon be using Solr 4’s pivot queries and hierarchical visualizations (e.g., treemaps) from D3.js to let patrons view and manipulate search results. We will be doing this with our VuFind 2.0 catalog, but this technique will work with any system running Solr 4. I will also talk about early student reaction to our tests of these visualization features.

More Like This: Approaches to Recommending Related Items using Subject Headings

Kevin Beswick, NCSU Libraries

With a significant portion of the collection at our new Hunt Library being housed in an automated storage and retrieval system, several of us at NCSU Libraries have begun looking at ways to replace and improve upon the classic shelf browsing experience in order to make it easier for patrons to browse related materials. Our goal is to mimic popular services like Amazon and Netflix, which utilize recommendation engines to make it easy for users to find items similar to a particular item of interest. While there have been previous efforts in libraries to recreate this experience using circulation or call number data, we are currently investigating algorithms that focus on use of subject headings. Use of subject headings as an alternative can be particularly helpful in the case of electronic materials that do not always have call numbers or circulation data. In this talk, I will share:

  • Details of the proposed algorithms
  • How these algorithms were quickly and easily implemented using Solr.
  • Our evaluation process and its outcomes in terms of the effectiveness of the algorithms.
  • How this has (or could) impact presentation of recommended items in our discovery layer.

Next Generation Catalogue - RDF as a Basis for New Services

Anne-Lena Westrum, Benjamin Rokseth, Asgeir Rekkavik, Petter Goksøyr Åsen

Oslo Public Library has converted the entire MARC-catalogue to RDF via the self-made conversion tool MARC2RDF.

data.deichman.no, the enriched RDF version of the library catalogue including its authority files, forms the basis for two different mashups; The Active shelf and the Book recommendation database. The RDF catalogue is linked with various content and the dataset is updated daily to account for additions, deletions and changes made in the MARC catalogue.

The Active shelf is a physical touchscreen device that makes use of open source software, RFID technology, RDF data and external web service APIs to provide information about any library book a patron is curious to know more about.

The Book recommendations database stores book recommendations written by library staff from all over Norway and links them to the RDF-representation of the MARC-catalogue.

Structured data NOW: seeding schema.org in library systems

Dan Scott, Laurentian University

The semantic web, linked data, and structured data are all fantastic ideas with a barrier imposed by implementation constraints. If their system does not allow customizations, or the institution lacks skilled human resources, it does not matter how enthused a given library might be about publishing structured data... it will not happen. However, if the software in use simply publishes structured data by default, then the web will be populated for free. Really! No extra resources necessary.

This presentation highlights Dan's work with systems such as Evergreen, Koha, and VuFind to enable the publication of schema.org structured data out-of-the-box. Along the way, we reflect the current state of the W3C Schema.org Bibliographic Extension community group efforts to shape the evolution of the schema.org vocabulary. Finally, hold on tight as we contemplate next steps and the possibilities of a world where structured data is the norm on the web.

Discovering your Discovery System in Real Time

Godmar Back and Annette Bailey, Virginia Tech

Practically all libraries today provide web-based discovery systems to their users; users discover items and peruse or check them out by clicking on links. Unlike the traditional transaction of checking out a book at the circulation desk, this interaction is largely invisible. We have built a system that records user's interaction with Summon in real-time, processes the resulting data with minimal delay, and visualizes it in various ways using Google Charts and using various d3.js modules, such as word clouds, tree maps, and others.

These visualizations can be embedded in web sites, but are also suitable for projection via large-scale displays or projectors right into the 'Learning Spaces' many libraries are converted into. The goal of this talk is to share the technology and advocate the building of a cloud-based infrastructure that would make this technology available to any library that uses a discovery system, rather than just those who have the technological prowess for developing such systems and visualizations in-house.

Personalize your Google Analytics Data with Custom Events and Variables

Josh Wilson, Systems Integration Librarian, State Library of North Carolina

At the State Library of North Carolina, we had more specific questions about the use of our digital collections than standard GA could provide. A few implementations of custom events and custom variables later, we have our answers.

I'll demonstrate how these analytics add-ons work, and why implementation can sometimes be more complicated than just adding a few lines of JavaScript to your ga.js. I'll discuss some specific examples in use at the SLNC:

  • Capturing the content of specific metadata fields in CONTENTdm as Custom Events
  • Recording Drupal taxonomy terms as Custom Variables

In both instances, this data deepened our understanding of how our sites and collections were being used, and in turn, we were able to report usage more accurately to content contributors and other stakeholders.

WebSockets for Real-Time and Interactive Interfaces

Jason Ronallo, NCSU Libraries

Watching the Google Analytics Real-Time dashboard for the first time was mesmerizing. As soon as someone visited a site, I could see what page they were on. For a digital collections site with a lot of images, it was fun to see what visitors were looking at. But getting from Google Analytics to the image or other content of what was currently being viewed was cumbersome. The real-time experience was something I wanted to share with others. I'll show you how I used a WebSocket service to create a real-time interface to digital collections views and search queries.

In the Hunt Library at NCSU we have some large video walls. I wanted to make HTML-based exhibits that featured viewer interactions. I'll show you how I converted Listen to Wikipedia [1] into an bring-your-own-device interactive exhibit. With WebSockets any HTML page can be remote controlled by any internet connected device.

I will attempt to include real-time audience participation.

Slides and Notes

Quick and Easy Data Visualization with Google Visualization API and Google Chart Libraries

Bohyun Kim, University of Maryland, Baltimore - Health Sciences and Human Services Library.

Slides: http://www.slideshare.net/bohyunkim/quick-easy-data-visualization-with-google-visualization-api-google-chart-libraries

Code: https://github.com/bohyunkim/examples

Do most of the data that your library collects stay in spreadsheets or are published as a static table with a series of boring numbers? Do your library stakeholders spend more time collecting the data than using it as a decision-making tool because the data is presented in a way that makes it hard for them to quickly grasp its significance?

This talk will provide an overview of Google Visualization API [2] and Google Chart Libraries [3] to get you started on the way to quickly query and visualize your library data from remote data sources (e.g. a Google Spreadsheet or your own database) with (or without) cool-looking user-controls, animation effects, and even a dashboard.

A Book, a Web Browser and a Tablet: How Bibliotheca Alexandrina's Book Viewer Framework Makes It Possible

Engy Morsy, Bibliotheca Alexandrina (The new Library of Alexandria)

A lot of institutions around the world are engaged in multiple digitization projects aiming at preserving the human knowledge present in books and availing them through multiple channels to people around the whole globe. These efforts will sure help close the digital gap particularly with the arrival of affordable e-readers, mobile phones and network coverage. However, the digital reading experience has not yet arrived to its maximum potential. Many readers miss features they like in their good old books and wish to find them in their digital counterpart. In an attempt to create a unique digital reading experience, Bibliotheca Alexandria (BA) created a flexible book viewing framework that is currently used to access its current collection of more than 300,000 digital books in five different languages which includes the largest collection of digitized Arabic books.

Using open source tools, BA used the framework to develop a modular book viewer that can be deployed in different environments and is currently at the heart of various BA projects. The Book viewer provides several features creating a more natural reading experience. As with physical books, the reader can now personalize the books he reads by adding annotations like highlights, underlines and sticky notes to capture his thoughts and ideas in addition to being able to share the book with friends on social networks. The reader can perform a search across the content of the book receiving highlighted search results within the pages of the book. More features can be further added to the book viewer through its plugin architecture.
