This paper describes the design and development of a learning object repository for a new statewide higher education initiative.

Paper for the 2014 Association for Information Science and Technology (ASIS&T) Annual Meeting. This paper discusses building a collection of web archiving research articles.

This paper describes the MARC Content Designation Utilization Project, which is examining a very large set of metadata records as artifacts of the library cataloging enterprise. This is the first large-scale examination of descriptive metadata utilization. Presents an overview of study activities and suggests the study's significance to the broader use of metadata in digital libraries.

This article discusses semantic document engineering with WordNet and PageRank.

This paper presents the results of the team of the University of North Texas in the Wikipedia image retrieval track of Image-CLEF-2010.

This paper presents a new area of research in library and information sciences - investigation into collection-level subject metadata that describes entire digital collections as integral wholes - and reports results of the multi-method exploratory study combining comparative content analysis of collection-level subject metadata in three large-scale aggregations of digital collections in the USA and Europe, transaction log analysis of user interactions with one of these portals, as well as interviews and observations of aggregation users.

This paper discusses interoperability of networked information. Interoperability is a fundamental challenge for networked information discovery and retrieval. Often treated monolithically in the literature, interoperability is multifaceted and can be analyzed into different types and levels. This paper discusses an approach to map the interoperability landscape for networked information retrieval as part of an interoperability assessment research project.

This paper reports the authors' TREC 2005 QA participation. The authors' QA system Eagle QA developed last year was expanded and modified for this year's QA experiments. Particularly, the authors used Lemur 4.1 as the Information Retrieval (IR) Engine this year to find documents that may contain answers for the test questions from the document collection. The authors' result shows Lemur did a reasonable job on finding relevant documents. But certainly there is room for further improvement.

This paper discusses Chinese information retrieval using Lemur, a freely available information retrieval toolkit.

This paper describes our participation in the NTCIR-5 CLQA task.

Paper for the 2010 International iConference. This paper discusses extraction and parsing of herbarium specimen data to make the critical information available in digital form.

This paper presents an overview of an exploratory research project to identify, describe, and investigate the applicability of the Web services (WS) approach to access legacy data.

This paper discusses the Z39.50 protocol. The ANSI/NISO Z39.50 protocol for information retrieval addresses the complex challenges of intersystem communication. Original uses envisioned for the protocol look very little like current implementations and uses. In the 1980s, users on one library catalog system would search and retrieve bibliographic records on a remote system. By the late 1990s, there was a need for discovering networked resources and integrating access to them. Yet, the Z39.50 protocol has addressed both these scenarios. This paper provides a portrayal of Z39.50 that explains its flexibility in response to a variety of information retrieval requirements in the networked environment.

Paper for the 2012 International iConference. This paper discusses the iCAMP (Information: Curate, Archive, Manage, and Preserve) project and building digital information curation curriculum.

This paper describes different instructional design strategies for teaching computer technological courses online.

Paper for the 2012 American Society for Information Science and Technology (ASIS&T) Annual Meeting. This paper discusses digital curation in the academic library job market.

This paper proposes a Retrieval Outcome Analysis Framework, or ROA Framework, to systematically evaluate retrieval performance of Cross-Language Information Retrieval systems.

Paper describing a plan of work to develop and test an alternative approach for interoperability testing. This approach builds on the conceptual and technical infrastructure developed during the Z-Interop Project.

Paper accompanying a poster presentation for the 2013 International iConference. This paper discusses teaching tools, applications, and infrastructure for digital curation through the use of a virtual lab.

This paper was part of a series by the Smithsonian Photography Initiative 'Click! Photography Changes Everything'. This paper discusses family photographs and how sometimes seemingly unremarkable snapshots can be truly remarkable.

Paper describing an analysis of subject representation in the Digital Public Library of America (DPLA), an aggregate digital library containing more than 8 million item-level metadata records at the time of the study. The findings provide information about the minimum, maximum, and average number of subjects in records from different hubs and hub types, as well as the distribution of unique subject terms across the entire collection.

This paper discusses building contextual mass in digital aggregations for scholarly use.
