Difficulties with navigation are common in hypertext documents. Many studies have examined techniques and design strategies to find the proper structure of a hyperdocument whereas others have investigated navigational tools such as overview diagrams, maps, menus, and/or tables of contents that help users navigate through complex hyperdocuments. This study has investigated the effects of table of contents and frames as user interface on user performance and user satisfaction. The result suggests several guidelines for designing complex hypertext information retrieval systems and creating on-line documentation.

Abstract The Centre de Données astronomiques de Strasbourg (CDS) has dealt with bibliographic information for many years. References of publications, published observational data related to objects, data tables, nomenclature, have been homogenized and organized into information retrieval systems: SIMBAD, the reference database for the identification and bibliography of astronomical objects; the catalogue service and the VizieR catalogue Browser, for data tables; the Dictionary of Nomenclature of Astronomical objects, which is now maintained by the CDS. Evolution in recent years has brought the Data Centers closer to the publishing process. General standards for astronomy, for the description of references and of data tables, have been proposed and implemented. Data tables from papers are now directly published in electronic form, and distributed on-line by the Data Centers. The emergence of fully electronic publication paves the way to innovative new services, linking the journals to other sources of informations (data bases, tables, then images, data archives), and making use of new methods for information retrieval. This also has an effect on the publishing process, with the possibility to implement new checks and links from text to other kinds of information (from objects names, positions, etc.). The CDS will bring some of thekey features in the evolution towards a fully linked astronomy information system, in close collaboration with the journal editors, the ADS, the other Data Centers, and the data providers.

Recent advances in computerized library retrieval methods can be used by clinicians and researchers alike, yet practicing professionals are often unaware of the ready accessibility of on-line and on-disk information retrieval systems. This paper provides an overview of commercial vendors and personal computer systems. Clinical applications are discussed.

Level Of Processing

An experiment is described which attempts to derive quantitative indicators regarding the potential relevance predictability of the intermediate stimuli used to represent documents in information retrieval systems. In effect, since the decision to peruse an entire document is often predicated upon the examination of one »level of processing« of the document (e.g., the citation and/or abstract), it became interesting to analyze the properties of what constitutes »relevance«. However, prior to such an analysis, an even more elementary step had to be made, namely, to determine what portions of a document should be examined.An evaluation of the ability of intermediate response products (IRPs), functioning as cues to the information content of full documents, to predict the relevance determination that would be subsequently made on these documents by motivated users of information retrieval systems, was made under controlled experimental conditions. The hypothesis that there might be other intermediate response products (selected extracts from the document, i.e., first paragraph, last paragraph, and the combination of first and last paragraph), that would be as representative of the full document as the traditional IRPs (citation and abstract) was tested systematically. The results showed that:1. there is no significant difference among the several IRP treatment groups on the number of cue evaluations of relevancy which match the subsequent user relevancy decision on the document;2. first and last paragraph combinations have consistently predicted relevancy to a higher degree than the other IRPs;3. abstracts were undistinguished as predictors; and4. the apparent high predictability rating for citations was not substantive.Some of these results are quite different than would be expected from previous work with unmotivated subjects.
