- A Study of State Library Agencies' Information Technology Standards Policies and Practices
- This report was commissioned and supported by the National Information Standards Organization (NISO). The dynamic pace of technology change challenges all organizations to identify and select standards on which to base mission-critical programs and services. State library agencies face particular challenges because of the increasing demands that publicly supported libraries provide access to increasing quantities and varieties of networked, digital and paper-based information resources and services. State library agencies are in a unique position to influence the adoption and implementation of standards to support statewide library resource sharing. This study, undertaken in 1998, attempted to bridge the gap of information and understanding about the current situation of state library agencies' use, opportunities and issues related to technical standards. digital.library.unt.edu/ark:/67531/metadc102301/
- A Study of State Library Agencies' Information Technology Standards Policies and Practices
- This report discusses standards in state library agencies. Little is known about state library agencies' policies for standards adoption and use. This study, undertaken in 1998, attempted to bridge the gap of information and understanding about the current situation of state library agencies' use, opportunities and issues related to technical standards. digital.library.unt.edu/ark:/67531/metadc36310/
- A Study of State Library Agencies' Information Technology Standards Policies and Practices: Final Report
- This report is on a study of state library agencies' information technology standards policies and practices. The National Information Standards Organization (NISO) sponsored this study to gain a better understanding of its target markets. As the national standards organization for the communities of libraries, information services, and publishers, NISO's goal for supporting this study was to understand state library agencies' concerns related to information technology standards. The study provides NISO with detailed information about the current use of standards by state library agencies and a set of recommendations to better serve the standards needs of state library agencies. Chief Officers of State Library Agencies (COSLA) endorsed the study since the data collected would assist its members in awareness of what each state library agency is doing with standards as well as the standards issues identified by the agencies. The study benefits COSLA by suggesting appropriate leadership opportunities for state library agencies in statewide standards policy development and deployment. The study also benefits the agencies by providing a compilation of their standards policies and procedures, and identifying barriers and best practices related to information technology standards. The structure of this report consists of a number of narrative sections and a set of appendixes with supporting information. digital.library.unt.edu/ark:/67531/metadc109719/
- Resource Discovery Using Z39.50: Promise and Reality
- 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. digital.library.unt.edu/ark:/67531/metadc36297/
- Assessing Interoperability in the Networked Environment: Standards, Evaluation, and Testbeds in the Context of Z39.50
- This book chapter discusses interoperability in the networked environment. An underlying assumption of any network is that various components and processes will work together to produce desired results (e.g., data transmission, data interchange, reliability of services, etc.). The term interoperability has been used to characterize this working together, especially, the workings of lower level data communication components. Usage of the term has evolved to refer more generally to the extent to which different types of computers, networks, operating systems, and applications work together effectively to exchange information in a useful and meaningful manner. Miller (2000) suggests a perspective That is even more encompassing: he says that to be interoperable means "one should actively be engaged in the ongoing process of ensuring that the systems, procedures and culture of an organisation are managed in such a way as to maximize opportunities for exchange and re-use of information, whether internally or externally." digital.library.unt.edu/ark:/67531/metadc102281/

- Mapping the Interoperability Landscape for Networked Information Retrieval
- 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. digital.library.unt.edu/ark:/67531/metadc36320/
- Improving Z39.50 Interoperability: Z39.50 Profiles and Testbeds for Library Applications
- This paper discusses Z39.50 interoperability. Abstract: 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. digital.library.unt.edu/ark:/67531/metadc36283/
- SQL Data Analysis Procedures to Create Aggregate and Candidate Record Groups on Sample of Decomposed MARC Records Phase 1 Testing
- This document describes the data analysis procedures developed to create the Aggregate and Candidate Record Groups using SQL statements. This is the preliminary version of these procedures tested and validated on a sample of decomposed MARC records. (For a description of how the MARC records were decomposed see the Z-Interop document, Decomposing MARC 21 Records for Analysis. A subsequent version may be necessary as the authors move to the procedures for the entire file of decomposed records. digital.library.unt.edu/ark:/67531/metadc111016/
- Data Normalization Procedures on Decomposed MARC 21 Records
- 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. digital.library.unt.edu/ark:/67531/metadc111005/
- ZDoctor Report of SIRSI Indexing Policies for Interoperability Testing: Phase 1 Testing
- This document discusses phase 1 of interoperability testing as part of the Z-Interop project. The ZDoctor perl program, which is proprietary software provided by Sirsi provides a way to verify the indexing policies established on the Unicorn online catalog reference implementation. ZDoctor produces a report that identifies the MARC fields and subfields that are indexed to support various Z39.50 Bib-1 Use Attributes. For Phase 1 interoperability testings, four Bath Profile searches will be used: Title search - keyword, Author search - keyword, Subject search - keyword, Any search - keyword. The indexing policies to support these searches were established according to the Z-Interop document, 'Indexing Guidelines to Support Z39.50 Profile Searches.' This document presents the output of the ZDoctor program. digital.library.unt.edu/ark:/67531/metadc111286/

This test dataset (hereafter referred to as the dataset) provides a controlled set of data for use in the Z39.50 Interoperability Testbed Project (hereafter referred to as Z-Interop). OCLC selected a 1% weighted sample from its WorldCat database, which contains approximately 45 million records. This document focused on the analysis procedures used to prepare for Phase 1 Testing in Spring 2002. A subsequent version of this document will address the additional procedures for Phase 2 Testing scheduled for Summer 2002. digital.library.unt.edu/ark:/67531/metadc110994/
- Virtual Libraries: A Service-Based Approach for Virtual Libraries
- This article discusses virtual libraries. Much of the expectation surrounding the emerging 21st century library is based on the opportunities presented by enhanced access to information resources through the use of networked information technologies. Existing libraries are a product of an intersection and an interaction of people, resources, and procedures. Libraries are defined by a range of services developed for internal and external consumption. The provision of services to patrons and other users, including library staff, is built upon the collective personnel, information, and technological resources that constitute the library. digital.library.unt.edu/ark:/67531/metadc36305/

- Decomposing MARC 21 Records for Analysis
- 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. digital.library.unt.edu/ark:/67531/metadc110995/

- Assessing Metadata Utilization: An Analysis of MARC Content Designation Use
- This paper discusses metadata utilization. Abstract: Metadata schemes emerge to meet community and user requirements, and they evolve over time to meet changing requirements. This paper reports results of an analysis of a large sample of MARC 21 bibliographic records. MARC 21 is an encoding scheme related closely to metadata elements occurring in library bibliographic records. The records were analyzed for the utilization of content designation available in MARC 21. Results indicate that less than 5% of available content designation accounts for over 80% of occurrences. The implications of these findings affect indexing policies, system design, and can inform setting requirements for extending a metadata scheme based on a threshold of community requirements. digital.library.unt.edu/ark:/67531/metadc36303/
- Hunting and Gathering on the Information Savanna
- In this book, the authors offer three different arenas of nontrivial information seeking for our consideration: "Submarine Chasing" explores the thoughts of a highly decorated Cold War submarine hunter. "Bounty Hunting" involves a long and convoluted search for a reported bond skipper. "Engineering Design" presents a content analysis of the few works in epistemological foundations of engineering design activity. These stories, told at great length and in considerable detail, are framed within a foundational model that links the simple act of document seeking to the broader issue of making one's way through life in the physical world. In each case, the authors ramble, mull, and stumble upon ideas without the least prior constraint, developing some threads quite fully and leaving others to tease us, but never ever throwing us to the lions. digital.library.unt.edu/ark:/67531/metadc83323/

- UNT at TREC 2004: Question Answering Combining Multiple Evidences
- This paper discusses Question Answering (QA) combining multiple evidences. QA aims at identifying answers to users' natural language questions. A QA system can release the users from digesting large amounts of text in order to locate particular facts or numbers. The research has drawn great attention from several disciplines such as information retrieval, information extraction, natural language processing, and artificial intelligence. TREC QA track has provided comparable QA system evaluation on a set of test questions since 1999. The degree of difficulty of the test questions has increased substantially in recent two years, which push the research toward applying more sophisticated strategies and better understanding of English texts. This article discusses this research. digital.library.unt.edu/ark:/67531/metadc96842/

- Project Work Plan Draft
- This document details a work plan to guide the planning and execution of a new phase of the Z39.50 Interoperability Testbed Project. In this phase, the project team will use a set of special, diagnostic MARC records 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 project team refers to these special, diagnostic records as radioactive MARC records. The project includes a number of separate but related activities. The structure of the work plan groups these activities into work areas, each of which describes the major activities, tasks, deliverables, timeliness, and responsibilities. The work areas are: creating MARC documentation database, developing radioactive MARC records, identifying test searches, enhancing indexing guidelines for searching, creating testing procedures and processes, validating radioactive MARC record approach for interoperability testing, and conducting interoperability testing. A number of these work areas will proceed in parallel, and there are interactions between the work areas. digital.library.unt.edu/ark:/67531/metadc111285/

- MARCdocs: The MARC 21 Bibliographic Format Database
- This document discusses MARCdocs. MARCdocs, the MARC 21 Documentation Database, is a pilot effort aimed at structuring the textual documentation from the MARC 21 Format for Bibliographic Data into a relational database. Using a database approach for the authoritative MARC documentation provides new opportunities for various applications, including more efficient maintenance of the documentation, easier and quicker updates and changes, exporting selected data in XML, as well as an aid to research into the development and evolution of MARC, a learning/reference tool for those seeking to understand the MARC format, and a tool to help those devising new bibliographic structures. The database was first envisioned by Dr. William Moen of the University of North Texas School of Library and Information Sciences as a tool for his ongoing research into metadata utilization and interoperability. Dr. Shawne Miksa, Penelope Bernardino, JungWon Yoon, and Jason Thomale have carried this idea forward to implementation. This application uses open source software tools including Linux, MySQL, and PhP. Jason Thomale, a masters student in the School of Library and Information Sciences, designed and implemented the database, developed procedures for data loading, and designed and programmed the web interface for the MySQL database. digital.library.unt.edu/ark:/67531/metadc111004/
- Creating Radioactive MARC Records and Z Queries Using the MARCdocs Database
- 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.

- An Extensible Approach to Interoperability Testing: The Use of Special Diagnostic Records in the Context of Z39.50 and Online Library Catalogs
- This paper discusses an extensible approach to interoperability testing. Assessing interoperability in the networked information services and applications environment presents difficult challenges due in part to the multi-level and multi-faceted aspects of interoperability. Recent research to establish an interoperability testbed in the context of Z39.50 protocol clients and servers and online catalog applications identified threats to interoperability and defined a question space for interoperability testing. This paper reports on follow-up research to develop an alternative approach for interoperability testing in the context of networked information retrieval that uses specially designed diagnostic records. These records, referred to as radioactive records, enable interoperability assessment at the protocol and semantic levels. This approach appears to offer an extensible method for interoperability testing for other metadata and protocol application environments. The resulting interoperability testbed incorporates additional components to exploit automatic processes for interoperability testing and assessment, thus improving the efficiency of interoperability testing. digital.library.unt.edu/ark:/67531/metadc102276/

- Toward a Unified Retrieval Outcome Analysis Framework for Cross-Language Information Retrieval
- This paper proposes a Retrieval Outcome Analysis Framework, or ROA Framework, to systematically evaluate retrieval performance of Cross-Language Information Retrieval systems. The ROA framework goes beyond TREC-type retrieval evaluation methodology by including procedures focusing on individual queries, especially difficult queries. The framework is comprised of four interrelated components: (1) Overall System Performance Evaluation, (2) Query Categorization, (3) Translation Analysis, and (4) Individual Query Analysis. An example of applying the framework is discussed in detail. The author believes the proposed framework would be especially useful for the development of real world Cross-Language Information Retrieval systems because the evaluation guided by the framework has the potential to discover causes behind poor retrieval performance. digital.library.unt.edu/ark:/67531/metadc132969/
- UNT 2005 TREC QA Participation: Using Lemur as IR Search Engine
- 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. digital.library.unt.edu/ark:/67531/metadc96841/

We expanded their TREC experimental QA system EagleQA this year to include Chinese QA and Cross-Language QA capabilities. Various information retrieval and natural language processing tools were incorporated with their home-built programs such as Answer Type Identification, Sentence Extraction, and Answer Finding to find answers to the test questions. Future development will focus on investigating effective question translation and answer finding solutions. digital.library.unt.edu/ark:/67531/metadc96830/
- Final Report for The Z39.50 Interoperability Testbed Project Phase 2: Developing an Alternative Approach for Interoperability Testing of Library Z39.50 Servers
- This report discusses the Z39.50 interoperability testbed project, phase 2. Abstract: The U.S. Federal Institute of Museum and Library Services (IMLS) awarded a National Leadership Grant in 2000 to support the research and demonstration project, 'Realizing the Vision of Networked Access to Library Resources: An Applied Research Demonstration Project to Establish and Operate a Z39.50 Interoperability Testbed.' In the project team's December 31, 2003 interim status report on the Z39.50 Interoperability Testbed Project (Z-Interop), the project team highlighted the challenges of individual libraries to participate in the Z-Interop testbed and the project team suggested an alternative method for interoperability testing for Z39.50 servers that could accommodate the limitations of individual library systems. In May, 2004, IMLS awarded an extension to the Z-Interop Project for additional research to develop and test an alternative approach for interoperability testing and also awarded approximately $50,000 in additional funding to carry out the research. The project team refers to this extension to the original award as Z-Interop Phase 2 or Z-Interop2. Research during Z-Interop2 built on the conceptual and technical infrastructure developed during the Z-Interop Project. digital.library.unt.edu/ark:/67531/metadc111287/

- Preparing, Creating, and Managing a Large Dataset of MARC 21 Records for Research and Analysis
- This poster discusses preparing, creating, and managing a large dataset of MARC 21 records. The MARC Content Designation Utilization (MCDU) Project is examining catalogers' utilization of available MARC 21 content designation (e.g., fields/subfields). A critical component of this project is the development of methods, procedures, and software tools for reliable and valid analyses of the complete WorldCat database of more than 56 million MARC 21 records. digital.library.unt.edu/ark:/67531/metadc77153/
