Paper for the 2011 ASIS&T Annual Meeting. This paper discusses open access and scholarly communication and the current landscape, future direction, and the influence on global scholarship.

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

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

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

This paper reports an exploratory study on resources and resource sharing among researchers in Intelligent Information Access (IIA).

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

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 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.

Paper discussing a two-dimensional approach for investigating issues of semantic interoperability in digital libraries.

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

This paper discusses the findings pertaining to the framework for building good digital collections. This paper is part of the three-year interim project report for the IMLS Digital Collections & Content Project, summarizing major findings October 2002 through September 2005.

This article discusses automatic keyword extraction for learning object repositories.

This paper presents a method for automatic topic identification using an encyclopedic graph derived from Wikipedia. The system is found to exceed the performance of previously proposed machine learning algorithms for topic identification, with an annotation consistency comparable to human annotations.

Paper for the 2012 International iConference. This presentation discusses data management and the DataRes 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.

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 discusses a project to redesign courses on different levels of details. The Texas Course Redesign Project initiated by the Texas Higher Education Coordinating Board (THECB) aims to develop and distribute instructional resources to improve student learning outcomes and lower the costs of higher education.

This paper discusses the Consortium for the Computer Interchange of Museum Information (CIMI)'s international effort to provide distributed search and retrieval of cultural heritage information. A primary aspect of CIMI's work utilizes ANSI/NISO Z39.50-1995, and American National Standard protocol for information retrieval. The International Organization for Standardization (ISO) recently approved Z39.50 as ISO 23950. CIMI chose Z39.50 to enable uniform access to existing and emerging digital collections and the vast repositories of cultural heritage information resources. These resources include a variety of physical and digital objects--physical artifacts and digital derivatives of those artifacts, descriptive records designed for collection management, bibliographic records, full-text documents, online tools such as thesauri and authoritative lists of artists' names, and more. CIMI's application Z39.50 in the networked cultural heritage information environment is breaking new ground in distributed and integrated access to textual and non-textual digital collections.

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.

An operating assumption for the networked environment is that many different information systems need to interoperate for users to successfully discover and retrieve distributed resources. Meaningful interoperability is often elusive. In the library community, the Z39.50 standard protocol (ISO 23950/ANSI/NISO Z39.50) for information retrieval promised seamless and transparent networked access to library resources. Too often, the reality has not lived up to the promise. This paper discusses two efforts that offer solution paths to Z39.50 interoperability.

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 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.

This paper discusses metadata utilization. This paper reports results of an analysis of a large sample of MARC 21 bibliographic records.
