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

This presentation discusses an exploratory study on resources and resource sharing among researchers in Intelligent Information Access (IIA). The investigation consists of two stages. In Stage One, the authors conducted a content analysis to identify resources used in 145 research papers and reports in two subfields of IIA; and in Stage Two, the authors carried out an online survey of IIA researchers to understand resource-sharing channels and the researchers' perspectives on resource sharing.

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

Final report for the Z39.50 interoperability testbed project, phase 2.

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.

This document is a draft version of the Z-Interop 2 project search and record data requirements for Z39.50 interoperability testing using radioactive MARC records.

This document provides a status report on the Z39.50 Interoperability Testbed Project (Z-Interop) covering the period of July 1, 2002 through December 31, 2002. The previous status report covered a three-month period from April 1, 2002 through June 30, 2002. This document highlights activities and accomplishments to communicate to IMLS progress on this project since the last status report.

This document serves as an interim report on the Z39.50 interoperability testbed, Phase 2 of the Z-Interop Project. This report covers the period of July 1, 2004 through December 31, 2004. This document highlights activities and accomplishments to communicate to IMLS progress on the project since the interim report on July 1, 2004.

This document provides a status report on the Z39.50 Interoperability Testbed Project (Z-Interop) covering the period of May 1, 2000 through March 31, 2002. Due to a family medical emergency, the Principal Investigator was not able to complete the six-month status report that was due December 1, 2001. The Principal Investigator (PI) communicated with the Institute of Museum and Library Services (IMLS) staff about this situation, and had sent via email in November 2001 information about the progress of the project.

This document details a work plan to guide the planning and execution of a new phase of the Z39.50 Interoperability Testbed Project.

This document discusses phase 1 of interoperability testing as part of the Z-Interop project.

Presentation for the 2005 American Society for Information Science and Technology (ASIS&T) Annual Meeting. This presentation discusses an alternative approach to interoperability testing and the use of special diagnostic records in the context of Z39.50 and online library catalogs.

This presentation discusses radioactive metadata records and an interoperability testing approach based on metadata utilization. The research is part of Z-Interop, an Institute of Museum and Library Sciences' (IMLS) National Leadership Grant supported project.

Report on the logic and procedures to create a test dataset of more than 400,000 (400K) MARC 21 records from the OCLC WorldCat database.

This document discusses decomposing MARC 21 records for analysis. To prepare the test dataset of the 1% sample of MARC 21 records from the WorldCat database for use in the Z39.50 Interoperability Testbed, the authors need to be able to efficiently analyze the records to determine relevant records to be returned for a set of test searches. The first step in that analysis is to determine the occurrence of test search terms in specific records. This document describes the general approach for this analysis and identifies specifications for the analysis.

This document provides guidelines for indexing MARC 21 records to support a set of searches using Z39.50. The Z39.50 Interoperability Testbed Project (Z-Interop) uses these guidelines to index the 400,000 MARC 21 records that comprise the Z-Interop reference implementation of the Z39.50 server and online catalog.

This report discusses the Z39.50 interoperability testbed and serves as an interim report for the Z-Interop Project as of December 31, 2003.

This document discusses a Z39.50 Interoperability Testing framework. In a first phase of the Z39.50 Interoperability Testbed, a large dataset of MARC records was used. In this work, the authors are exploring how a set of special, diagnostic MARC records can be developed and used to identify interoperability problems between a Z39.50 client and a Z39.50 server providing access to a database of bibliographic records supporting the search and retrieval functions of an online library catalog. The authors refer to these special, diagnostic records as radioactive MARC records. It discusses the various components and identifies the tasks related to developing and implementing the components.

This document describes how the authors can extend a relational database of MARC documentation to store the appropriate information that will support the automatic generation of the special, diagnostic MARC records the authors will call radioactive MARC (RadMARC) records. The information contained in the database will also support the generation of the Z queries used in the interoperability testing.

Report on the MARC 21 bibliographic format database.

In this document, the authors present some aspects of data normalization of the decomposed records to improve the results of analysis. The data normalization processes use pattern-matching techniques to eliminate and/or generalize anomalous characters and terms. Since the unit of analysis in preparing the test dataset of 400,000 MARC 21 records is a "word," there was a need for data normalization to provide reliability in the subsequent analysis.

Poster presented at the 2007 International Conference on Open Repositories. This poster discusses the Metadata Education and Research Information Commons (MERIC). MERIC originated from an action plan of the Library of Congress and addresses the need to prepare future information professionals to organize and provide access to digital resources.
