Digital Image Access & Retrieval

The 33th Annual Clinic on Library Applications of Data Processing, held at the University of Illinois at Urbana-Champaign in March of 1996, addressed the theme of "Digital Image Access & Retrieval." The papers from this conference cover a wide range of topics concerning digital imaging technology for visual resource collections. Papers covered three general areas: (1) systems, planning, and implementation; (2) automatic and semi-automatic indexing; and (3) preservation with the bulk of the conference focusing on indexing and retrieval.published or submitted for publicatio

Evaluation of Public Services and Public Services Personnel (Papers presented at the Allerton Park Institute held October 28-30, 1990)

On three magnificent late fall days in October 1990, 150 librarians met at Allerton Park to grapple with the issues of evaluation of public services and public services personnel. These proceedings are the formal record of the 1990 Allerton Institute although, clearly, they cannot fully convey the experiences shared by the participants. The papers document the formal presentations, but they do not reflect the atmosphere of intense debate inside the Allerton conference buildings that contrasted so strongly with the lazy sunshine and the beauty of the late fall foliage outside. Keynote speakers are supposed to start the debate by outlining the issues. James Rettig certainly was effective in starting the process of creative dialog. He reminded us that evaluation cannot begin until we have clearly understood goals and objectives. He then raised a number of objections to one of our more cherished ideals and objectives in reference work: that of providing bibliographic instruction. Reading his paper may provide a partial insight into the discussion that it generated. After the keynote presentation, papers presented theories and practical examples, overviews and individual experiences. This range of coverage was planned, as was the balance between speakers from library education and from the practice of public service librarianship. Tom Childers gave an overview of the history and capabilities of unobtrusive evaluation; then Wilf Lancaster, Alan Nourie and Cheryl Elzy presented a specific instance of unobtrusive testing in which they expanded the boundaries of the method by evaluating individual service providers. Charles Bunge spoke about a thoroughly tried-and-tested mechanism for evaluating what goes on in a reference encounter; following him, Prudence Dalrymple discussed ways in which information science research can point out new directions for evaluating information services. Mary Goulding's paper described a classic approach to objectives-based evaluation, while Betty Turock suggested six or seven additional kinds of evaluation that might be attempted. Finally, Rick Rubin gave a masterful survey of personnel evaluation for public service librarians, and Geraldine King provided a specific example of peer evaluation.published or submitted for publicatio

El análisis documental de la fotografía de prensa en entornos automatizados

Se investiga el proceso de análisis documental de las fotografias almacenadas en los fondos documentales de aquellas instituciones de carácter periodístico que usan imágenes fotograficas para la elaboración de sus productos de información. Se analiza la sistematización de los procesos documentales con objeto de posibilitar la recuperación eficiente y eficaz de las imágenes que demandan los profesionales. Se inicia el trabajo con una introducción teórica. Se indaga, a continuación, acerca de la naturaleza física e informativa del documento, se define entorno funcional, legal, institucional y ético del archivo fotográfico de prensa. Se abordan las técnicas de recuperación sobre herramientas informáticas aplicables a la imagen fotográfica. Finalmente, se propone un modelo teórico de análisis y recuperación icónico basado en un sistema de representación formatizado de contenido inspirado en técnicas de representación del conocimiento empleadas en el campo de la Inteligencia Artificial
