Using Encyclopedic Knowledge for Automatic Topic Identification

Description: 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.

CIMI's Z39.50 Interoperability Testbed: Search and Retrieval of Distributed Cultural Heritage Information

Description: 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.

Resource Discovery Using Z39.50: Promise and Reality

Description: 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.

Improving Z39.50 Interoperability: Z39.50 Profiles and Testbeds for Library Applications

Description: 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.

A Study of State Library Agencies' Information Technology Standards Policies and Practices

Description: 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.

No Longer Under Our Control: The Nature and Role of Standards in the 21st Century Library

Description: This lecture script examines the nature and role of standards for the emerging 21st century library. Given the dynamic character of the networked environment, when are standards appropriate and how can they be developed in a manner consistent with the volatility of information technologies and changing library services? What are the roles and responsibilities of standards developing organizations, technology vendors, content creators, and librarians for standards? Do local practices of libraries threaten standards-based resource sharing and resource access technologies? Can local needs be balanced with broader library community responsibilities, and how do standards affect this balance? The speaker's assumption is that adherence to standards has never been more critical, yet his implementation experience with Z39.50 and MARC suggests that the commitment to national and international standards by librarians, technology vendors, and content creators are often an example of good intentions rather than actual practice. This standards disconnect threatens the emerging 21st century library's ability to deliver fundamental services in appropriate ways to their users.

Mapping the Interoperability Landscape for Networked Information Retrieval

Description: 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.

Needs Assessment Survey Report

Description: This report is part of the Web-at-Risk project. The Web-at-Risk project is one of eight digital preservation projects funded in 2004 by the Library of Congress. The project is a 3-year collaborative effort of the California Digital Library (CDL), the University of North Texas (UNT), and New York University (NYU). The project will develop a Web Archiving Service that enables curators to build collections of web-published materials. The content of the collections for this project will be largely from US federal and state government agencies, but will also include political policy documents, campaign literature, and information surrounding political movements and labor unions. This report includes the methods, results, discussion, and appendices related to the Web-at-Risk project.

Needs Assessment Survey Report: Abbreviated Version

Description: This report is part of the Web-at-Risk project. The Needs Assessment Toolkit created for the Web-at-Risk project describes the project's needs assessment activities and includes data collection tools, which are designated to identify the needs and requirements of curators, web-content producers, and end users with regard to the Web Archive Service. Additionally, information gathered by some of the data collection tools will help to identify curators' requirements for the web crawler and its crawl analyzer tool, which will be developed as part of the project. Each of the assessment activities described in the Needs Assessment Toolkit was designated to follow a collection development framework for web archives. This report contains a data analysis of the survey results. Results from focus group discussions and interviews with content providers and end users are presented in separate reports.

Learning from Artifacts: Metadata Utilization Analysis

Description: 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.
