Goals for HTRC
• Provide a persistent and sustainable structure to
enable scholars to ask and answer new questions.
– Leverage data storage and computational infrastructure at Indiana
& Illinois
– Stimulate community development of new functionality and tools
– Use tools to enable discoveries that would not be possible
without the HTRC
• Enable scholars to fully utilize content of HathiTrust
Library while preventing intellectual property misuse
within U.S. copyright law.
– Provide a secure computational and data environment for
scholars to perform research using HathiTrust Digital Library.

8. Non-Consumptive
Research

9. 4/18/15 #HTRC @HathiTrust
Non-Consumptive Research Paradigm
• No action or set of actions on part of users,
either acting alone or in cooperation with
other users over duration of one or multiple
sessions can result in sufficient information
gathered from collection of copyrighted works
to reassemble pages from collection.
• Definition disallows collusion between users,
or accumulation of material over time.
Differentiates human researcher from proxy
which is not a user. Users are human beings.

ACS (Advanced Collaborative Support)
1. Tracing Technology Diffusion Over Time: Dr. Michelle Alexopoulos, a scholar in
economics from the University of Toronto.
2. Detecting Literary Plagiarisms: The Case of Oliver Goldsmith: Douglas Duhaime.
University of Notre Dame: Will work on developing tools for detecting
plagiarisms. He will focus on the case of Oliver Goldsmith, to detect the literary
thefts of Goldsmith by using machine learning techniques.
3. Taxonomizing the Texts: Towards Cultural-Scale Models of Full Text: Colin Allen,
Jaimie Murdock. Indiana University Bloomington. Allen and Murdock will carry
out a cultural-scale investigation and topic modeling on HT public-domain full
text through random sampling to select collections according to the Library of
Congress Subject Headings (LCSH).
4. The Trace of Theory. Geoffrey Rockwell, Laura Mandell, Stefan Sinclair, Matthew
Wilkens, Susan Brown. University of Alberta, Texas A&M University, University of
Notre Dame. Aim to subset theoretical subsets from the HT public corpus and
apply large-scale topic modeling on the subsets. The researchers will develop
tools and computational methods for tracking the concept of "theory.”

HTRC Data Capsule for Secure Text-
Mining at Scale
Funded at $606,000 by The Alfred P. Sloan Foundation; Beth
Plale, Indiana University, PI; Atul Prakash, University of Michigan,
Co-PI; Fall 2011 – Fall 2014.
Goal: Prototype a system that enables secure text mining to be
carried out at scale using public cloud resources, including:
1. a software cloud infrastructure based on OpenStack
2. mechanisms for managing a secure virtual machine We plan
The Sloan Cloud will provide users with dedicated virtual
machines that are pre-configured with appropriate tools and
provide secure access to remote data that cannot be funneled
through the VM to outside filesystems.
