Summary:
HathiTrust Research Center (HTRC) is the public research arm of the HathiTrust digital library where millions of volumes, such as books, journals, and government documents, are digitized and preserved. By Nov 2013, the HathiTrust collection has 10.8M total volumes of which 3.5M are in the public domain [1] and the rest are in-copyrighted content. The public domain volumes of the HathiTrust collection by themselves are more than 2TB in storage. Each volume comes with a MARC metadata record for the original physical copy and a METS metadata file for provenance of digital object. Therefore the large-scale text raises challenges on the computational access to the collection, subsets of the collection, and the metadata. The large volume also poses a challenge on text mining, which is, how HTRC provides algorithms to exploit knowledge in the collections and accommodate various mining need. In this workshop, we will introduce the HTRC infrastructure, portal and work set builder interface, and programmatic data retrieve API (Data API), the challenges and opportunities in HTRC big text data, and finish with a short demo to the HTRC tools. More about HTRC The HTRC is a collaborative research center launched jointly by Indiana University and the University of Illinois, along with the HathiTrust Digital Library, to help meet the technical challenges of dealing with massive amounts of digital text that researchers face by developing cutting-edge software tools and cyberinfrastructure to enable advanced computational access to the growing digital record of human knowledge.

Courtney, Angela, Dalmau, Michelle
Summary:
In preparation for the opening of the Indiana University Libraries' Scholars' Commons, staff from across the libraries including, Collection Development & Scholarly Communication, Library Technologies, Reference Services, and Arts & Humanities, will engage in an extended, hands-on learning project known as Research Now: Cross Training for Digital Scholarship. Our project team will develop a digital archive tentatively called The History of the Indiana University Libraries, which is conceived as a comprehensive, multimedia, and perpetual digital archive documenting the earliest days of the Indiana University (IU) Libraries through present times. The archive will serve as an engaged learning opportunity for first-year, front line Scholars' Commons staff as we retool our skills and knowledge in preparation for the opening of the Scholars' Commons. The project aims to: consolidate two parallel web sites that cover the history of the IU Libraries by migrating the existing content into services such as Archives Online, Image Collections Online, and other services for long-term digital preservation and access digitize and describe existing content (35 mm slides, photographs, manuscripts, newspaper clippings and other ephemeral materials and objects) held by Lou Malcomb, Head of Social Sciences, Gov Docs and GeoSciences cross-reference existing digital content about the libraries' history from related resources and repositories identify, digitize, and describe additional materials in existing repositories across campus create and compile original primary and secondary source contextual information by way of oral histories, essays, timelines and chronologies, biographical sketches, bibliographies, and other related information Above all, this is a learning project for frontline Scholars' Commons staff with three broad goals: to understand the multi-faceted dimensions, iterations and phases involved in designing and developing a curated digital archive to contribute to this project as researchers to cultivate ad-hoc learning strategies Cross-training began in mid-November 2013, and we would like to take this opportunity to provide you with an overview of our praxis-based cross-training initiative, and an update several months into our program.

6. Using Omeka: Cultural Heritage Projects at Indiana University (55:21)

Main contributors:
Cowan, William, Jenns, Erika, Smith, Ardea
Summary:
In recent years, Omeka has become an important tool for the exhibit of digital object collections. As with many technologies, Omeka can present some issues with setup and configuration, but overall, Omeka is easy to use for managing digital content. A few of the recent projects to use Omeka are the Lilly Library's War of 1812 (http://collections.libraries.iub.edu/warof1812/) and Indiana University Library Moving Image Archive's World War II Propaganda Films (http://collections.libraries.iub.edu/IULMIA/). The two projects discussed at this session are the Don C. Belton memorial site by the English Department, presented by Erika Jenns, and the ‰ÛÏRegeneration in Digital Contexts: Early Black Film‰Û conference and workshop site presented by the Black Film Center/Archive graduate assistant Ardea Smith. Using Omeka to Represent the Library of Professor Don C. Belton (http://belton.indiana.edu/) presented by Erika Jenns Using my experiences cataloguing the collection of Professor Don Belton, the late novelist, book collector, and English professor at Indiana University Bloomington, I will address the benefits of using Omeka to create a dynamic access point for users. After Belton's death in 2009, the bulk of his collection was transferred to branch libraries on campus. Remaining books were kept by IU's English Department, which does not have a formal library. To make the collection more visible, I created an Omeka website, meant to function as a precursor to a visit to the collection. The site uses tags, rendering it more searchable. It also includes scans of book covers, digitized videos of Belton lecturing and reading, and posts by students who have worked with the collection. The site represents Belton's books both physically and electronically. Coupled with biographical information, it highlights Belton's research interests, sources of inspiration, and some of the works he produced. The Proceedings of Regeneration in Digital Contexts: Early Black Film (http://www.indiana.edu/~regener8/regeneration/) presented by Ardea Smith In 2013, the Black Film Center/Archive received a National Endowment for the Humanities Level I Digital Humanities Start-Up Grant to convene an interdisciplinary group of scholars, archivists, curators, and digital humanities technology specialists for a two-day conference and workshop, ‰ÛÏRegeneration in Digital Contexts: Early Black Film.‰Û The conference and workshop proceedings were documented on video and fully transcribed. To enhance public access to these proceedings, I oversaw the creation of a website utilizing the open-source Omeka platform and VideoStream 2 plugin designed by project advisor Will Cowan at Indiana University. The website anchors streaming video content to keyword-searchable transcripts of the event proceedings. Drawing on the development process for the ‰ÛÏRegeneration‰Û website, my presentation will discuss the practical issues of building of an Omeka-based site using IU's webserve system with an aim to help individuals new to digital archival creation.

7. Globalization of the US: From Digital Research Project to Digital Library Services (49:09)

Date:
2014-12-10
Main contributors:
Dalmau, Michelle, Dowell, Erika
Summary:
As part of an exhibition at the Lilly Library entitled The Globalization of the United States, 1789-1861 scheduled to open September 15, historian Konstantin Dierks and librarians Erika Dowell and Michelle Dalmau have partnered to create a digital counterpart to the physical exhibit that includes an interactive, map-based visualization. The visualization tracks several data points or ‰ÛÏfacets‰Û about U.S. interventions in the rest of the globe, from diplomatic missions to stationed military squadrons. As Dierks describes, it provides a tool for scholars and students to investigate how ‰ÛÏthe United States, no longer swaddled within the British empire, sought to recalibrate its interaction with the wider world as an independent nation.‰Û This presentation will focus primarily on one component of the digital exhibit, the map-based visualizations, and how we in the libraries have been able to use this project as a use case for generalizing research-oriented treatment of geospatial and temporal data. By abstracting the data gathering and mapping processes and building workflows to support these activities, we have the beginnings of a services-oriented approach to map-based discovery and inquiry that could be leveraged by other digital research projects at Indiana University. As part of this presentation we will: a) evaluate the various map-based tools with which we experimented including SIMILE Exhibit, Google Fusion, Neatline, and Leaflet, b) review the metadata challenges particular to this project and how they can be abstracted for future projects, and c) relay lessons learned when working with historical maps. We will conclude by proposing a model established by Professor Dierk's project team, using a combination of tools and techniques referenced above, as a way forward in supporting map-based digital research projects more generally.

8. IU's participation in the Hydra Project: Many Heads, one Repository Solution Framework (58:54)

Date:
2014-02-19
Main contributors:
Dunn, Jon, Cowan, William, Notess, Mark
Summary:
The Hydra Project is a large collaboration among many institutions sharing needs for open software digital repository solutions. Indiana University is a Hydra Partner, and as such, is both developing new Hydra "heads" and leveraging heads developed by other partners. In this presentation, we will describe the Hydra Project objectives, the primary components of the technology (Fedora, Solr, Blacklight), how the community collaborates, and the benefits of this collaboration. The Avalon Media System was our first Hydra-based project, but now we are also collaborating on a new institutional repository solution as well as a new "page turner" Hydra head for digitized paged media. The Hydra Partner community holds great promise for lower cost, tailorable digital repositories for libraries and archives.

9. Better Doctors, Better Patients, Better Decisions (1:35:21)

Summary:
In modern high-tech health care, patients appear to be the stumbling block: an uninformed, anxious, noncompliant folk with unhealthy lifestyles who demand treatments advertised by celebrities, insist on unnecessary but expensive imaging, and may eventually turn into plaintiffs. Patients’ lack of health literacy has received much attention. But what about their physicians? I show that the majority of doctors are innumerate, that is, they do not understand basic health statistics. An estimated 70%–80% of them do not understand what the results of screening tests mean. This engenders superfluous treatment, anxiety, and healthcare costs. As a consequence, the ideals of informed consent and shared decision-making remain a pipedream; both doctors and patients are habitually misled by biased information in health brochures and advertisements. I argue that the problem is not simply in the minds of doctors, but in the way health statistics are framed in journals and brochures. A quick and efficient cure is to teach efficient risk communication that fosters transparency as opposed to confusion. I report studies with doctors, medical students, and patients that show how transparent framing helps them understand health statistics in an hour or two. Raising taxes or rationing care is often seen as the only viable alternative to exploding health care costs. Yet there is a third option: by promoting health literacy, better care is possible for less money.

10. Simple Heuristics for a Complex World (1:43:32)

Summary:
Whom to marry? How to invest? Whom to trust? Complex problems require complex solutions – so we might think. And if the solution doesn’t work, we make it more complex. That recipe is perfect for a world of known risks, but not for an uncertain world, as the failure of the complex forecasting methods leading to the 2008 financial crisis illustrates. In order to reduce estimation error, good inferences under uncertainty counter-intuitively require ignoring part of the available information,. Less can be more. Yet although we face high degrees of uncertainty on a daily basis, most of economics and cognitive science deals exclusively with lotteries and similar situations in which all risks are perfectly known or can be easily estimated. In this talk, I invite you to explore the land of uncertainty, where mathematical probability is of limited value and people rely instead on simple heuristics, that is, on rules of thumb. We meet Homo heuristicus, who has been disparaged by many psychologists as irrational for ignoring information—unlike the more diligent Homo economicus. In an uncertain world, however, simple heuristics can be a smart tool and lead to even better decisions than with what are considered rational strategies. The study of heuristics has three goals. The first is descriptive: to analyze the heuristics in the “adaptive toolbox” of an individual or an institution. The second goal is normative: to identify the ecological rationality of a given heuristic, that is, the structures of environments in which it succeeds and fails. The third goal is engineering: to design intuitive heuristics such as fast-and-frugal trees that help physicians make better decisions.

12. Putting on Something More Revealing: Exposing Our Fedora Data (41:37)

Date:
2014-04-02
Main contributors:
Hardesty, Julie, Shelby, Jacob
Summary:
IU's Fedora digital repository houses thousands of digitized items including pages of text, photographs, puzzles, three-dimensional artifacts, prints, audio, and moving pictures. These items are made accessible either through silo-ed collection sites or as a certain type of digital object (like images or finding aids). But there is a larger corpus of the entire repository that should be shared for greater understanding, discoverability, and use. Exposing the metadata we have in our repository allows others to make use of it, offering different perspectives on our items and collections and combining our collections with other similar collections around the world. Join us for the latest on our work to reveal our digital collections as data feeds.

Main contributors:
Hardesty, Juliet
Summary:
How do you usefully combine digital repository, library catalog, and library web site data so researchers can discover and make use of the data in support of their research? This session discusses plans to combine IU Libraries' digital repository data with library catalog and IUB Libraries' web site data to create a Solr-indexed data source that preserves context and provides thorough, useful, and sharable access to the information, collections, and resources at the Indiana University Libraries.

14. Consciousness as a Problem in Philosophy and Neurobiology (1:20:19)

Date:
2014-09-09
Main contributors:
John Searle
Summary:
A main intellectual scandal today is that we do not have, in philosophy or neurobiology, a generally accepted account of consciousness. In this lecture, John Searle will offer the philosophical core of such an account, and explain the difficulties in getting a neurobiological account. Along the way, he will expose half a dozen really outrageous mistakes about consciousness.

15. The Logical Structure of Human Civilization (1:24:07)

Date:
2014-09-11
Main contributors:
John Searle
Summary:
The distinctive features of human civilization, as opposed to animal societies, are such things as money, property, marriage, government, etc. These are created and partly constituted by linguistic representations. For this reason, they all have logical, propositional structures. John Searle will explain how they are created and maintained by certain sorts of speech acts and thus explain the nature of human civilization.

17. An Introduction to Using Neatline for Digital Mapping Projects (56:50)

Date:
2014-03-12
Main contributors:
Marshall, Brianna
Summary:
Neatline, a tool for the open-source Omeka framework that allows users to create digital exhibits with maps and timelines, was created to fit the needs of scholars, librarians, historians, and digital humanists. In this talk, the speaker will share an introduction to Neatline, her experiences using the tool for a mapping project with IU's Digital Collections Services, and suggestions for libraries interested in exploring Neatline themselves.

19. The Library User Experience: Why it matters and how it can be improved (50:23)

Date:
2014-04-23
Main contributors:
Notess, Mark
Summary:
User Experience (UX) encompasses not just usability but a customer's total experience of products, services, and organizations. This talk focuses on the technology-mediated experience people have with the Libraries. I begin by explaining the key concepts of UX and give some examples of why it matters to us. I will describe a range of UX methods for improving UX and will talk about how those methods can be applied to technology-based products and services in the Libraries. I will also summarize the charter of the new UX consulting group in the Bloomington Libraries and describe we can assist with UX improvements. Although this talk will focus on libraries, most of it will apply to any technology-based project.
