This paper presents a case study of the work carried out by the University of North Texas (UNT) Libraries and the intersection of metadata modeling, metadata input rules and documentation, metadata quality assessments, and technology to empower metadata editors to create high-quality metadata.

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.

Paper for the 2015 International iConference. This paper discusses a study exploring metadata change in a digital repository.

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.

Paper describing the results of initial research to evaluate general information about how records change in a digital library, using the UNT digital collections as a sample set. The analysis looked at several key concepts including the number of records that have been edited, the number of edits per record, the number of editors per record, the amount of change in file size and in completeness (i.e., values in required fields), and changes in access to digital objects.

Article on an innovative partnership to recruit and educate biomedical information professionals.

This paper accompanies a poster presented at the 2010 Library Research Seminar V Conference. This paper and the accompanying poster discuss what transaction log data tells us about collection-level subject access.

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.

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 discussing the use of special diagnostic records in the context of Z39.50 and online library catalogs.

This paper discusses Question Answering (QA) combining multiple evidences.

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 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.

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

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 discusses assessing descriptive substance in free-text collection-level metadata. This paper reports on a content analysis of collection records in an aggregation of cultural heritage collections.

This two-year project will advance understanding of the workflow and processes best able to increase access to and use of digitized biological collection metadata within the stakeholder communities comprised of biologists, natural history museum collections managers, biodiversity standards groups, and the library and information science community.
