App Authors: Closing the App Gap II

Time frame
2014-Present
Investigators
Deborah Stevenson, Kate McDowell
Total funding to date
$248,205.00
Funding agency
Institute of Museum and Library Services

The focus of this three-year, multisite project is development of app-based curricula and tools for use in school and public libraries. These tools will teach children aged eight to twelve how to build their own apps, providing them with early programming experience, and allow them to share their creations with other children. The project further establishes libraries as places to engage youth…

The HathiTrust has provided funding for the HathiTrust Research Center (HTRC), colocated at University of Illinois and Indiana University, to serve as the research arm of the HathiTrust and create an agile, technology-rich service for researchers in the digital humanities, social sciences, natural sciences, and informatics. This service will help researchers conduct nonconsumptive research on…

Natural Language Processing for Building and Enhancing Graph Data and Theory

Investigator
Jana Diesner

How can we use user-generated content to construct, infer or refine network data? We have been tackling this problem by leveraging communication content produced and disseminated in social networks to enhance graph data. For example, we have used domain-adjusted sentiment analysis to label graphs with valence values in order to enable triadic balance assessment. The resulting method enables…

Diesner’s team is developing a natural-language processing solution for probabilistic entity detection and classification in the domain of healthcare. The core of the solution are prediction models built by using supervised and/or semi-supervised machine learning techniques. The resulting models can be used to annotate natural language text data documents for entity classes. The team will…

Taxonomists are scientists who describe the world’s biodiversity. These descriptions of millions of species allow scientists to do many different kinds of research, including basic biology, environmental science, climate research, agriculture, and medicine. The problem is that describing any one species is not easy. The language used by taxonomists to describe their data is complex, and…

Repository Services for Accessible Course Content

Across the country, colleges and universities are struggling to meet demand for accessible forms of course materials for students with an array of disabilities. At present, each institution is addressing this problem individually, at great expense, and often without full campus coordination, much less consortial collaboration. Locating digital files is difficult and entails numerous sources.…

Research Software Credit and Sustainability

Time frame
2014-Present
Investigator
Daniel Katz

An ever-increasing fraction of research is dependent on software, much of it developed in academia. But the developers are often not recognized or rewarded for their contributions in the academic systems. In addition to recognition, resources are needed to sustain research software: to continue to make it available in the future, on new platforms, meeting new needs. This project examines both…

Transforming Taxonomic Interfaces

Investigator
Michael Twidale
Total funding to date
$421,200.00
Funding agency
National Science Foundation

The goal of this research is to help researchers develop and use relatively simple tools to describe species in a way that make those descriptions easier to share with other scientists and easier for computers to process and analyze. The approach is bottom-up and iterative, involving the rapid prototyping of tools, combining of existing tools, and the tailoring of applications developed for…
