- Abstract
- Describes the final phase of the work on the ELINOR (Electronic Library INformation Online Retrieval) project at De Montfort University, Leicester, which concluded in 1996. ELINOR was 2 phase project with 3 overall goals: to create a practical pilot system based on a commercial product (Excalibur EFS); to investigate the expansion of a small scale electronic library to a larger, distributed library system; and to develop a more efficient and effective means of accessing and sharing resources within a networked multi campus institution. ELINOR was successful in demonstrating that libraries may conveniently digitize and supply smal collections of high demand materials over a campus network in text anf TIFF format. Operational conditions have so far indicated that the barriers are not technological but involve copyright, use issues and sustainability

- Abstract
- Reports on the findings of the major study, carried out by the Royal Society, etc. and prompted by the concern felt about the increasing signs of strain in the scientific, technical and medical information systems (STM) and the consequences for technical research. The report is a follow up to the earlier study (BLRDD report 5626) with the aim of covering the trends which have developed since the earlier report was published (online information retrieval, electronic networks, CD-ROM etc.). The study covers: the nature of the UK scientific, technical and medical information system; users of the STM information system; the changing role of libraries and librarians with regard to periodicals, books and other services; economic aspects of the STM information system (research libraries, primary publishing, secondary publishing, and value of scientific research); economic aspects of the STM information system, and perceived problems and potential changes with regard to primary periodicals, electronic periodicals, user interaction, and funding of the services. The data derived from the user survey and the library survey are published in full with analysis. Presents the conclusions and recommendations arising from the study

- Abstract
- In der folgenden Studie wird eine Komponente für eine visuelle Benutzerschnittstelle zu Textdatenbanken entworfen. Mit Hilfe einer Terminologievisualisierung wird dem Benutzer eine Hilfestellung bei der Relevanzbewertung von Dokumenten und bei der Erweiterung seiner visuellen Anfrage an das Retrieval-System gegeben. Dazu werden zuerst die grundlegenden Information-Retrieval-Modelle eingehender vorgestellt, d.h., generelle Retrieval-Modelle, Retrievaloperationen und spezielle Retrieval-Modelle wie Text-Retrieval werden erläutert. Die Funktionalität eines Text-Retrieval-Systems wird vorgestellt. Darüber hinaus werden bereits existierende Implementierungen visueller Information-Retrieval-Benutzerschnittstellen vorgestellt. Im weiteren Verlauf der Arbeit werden mögliche Visualisierungen der mit Hilfe eines Text-Retrieval-Systems gefundenen Dokumente aufgezeigt. Es werden mehrere Vorschläge zur Visualisierung von Thesauri diskutiert. Es wird gezeigt, wie neuronale Netze zur Kartierung eines Eingabebereiches benutzt werden können. Klassifikationsebenen einer objekt-orientierten Annäherung eines Information-Retrieval-Systems werden vorgestellt. In diesem Zusammenhang werden auch die Eigenschaften von Thesauri sowie die Architektur und Funktion eines Parsersystems erläutert. Mit diesen Voraussetzung wird die Implementierung einer visuellen Terminologierunterstützung realisiert. Abschließend wird ein Fazit zur vorgestellten Realisierung basierend auf einem Drei-Schichten-Modell von [Agosti et al. 1990] gezogen.

- Abstract
- Describes the results of a project to develop conflation tools for searching databases of Latin text. Reports on the results of a questionnaire sent to 64 users of Latin text retrieval systems. Describes a Latin stemming algorithm that uses a simple longest match with some recoding but differs from most stemmers in its use of 2 separate suffix dictionaries for processing query and database words. Describes a retrieval system in which a user inputs the principal component of their search term, these components are stemmed and the resulting stems matched against the noun based and verb based stem dictionaries. Evaluates the system, describing its limitations, and a more complex system

- Abstract
- Addresses the problems of content retrieval in the construction of pictorial database management systems. Presents a generalisable architecture for the effective identification of specific pictures from a large collection and describes prototype system based on this architecture successfully implemented. The architecture consists of 3 main components: picture description; picture indexing and filing, and picture retrieval. The description of pictures is facilitated by using the main semantic concepts employed in the entity-attribute-relationship model. The chief function of the picture indexing and filing component is to convert the logical representations into a relational data format to prepare for subsequent processing initiated by picture queries

- Abstract
- The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project

- Abstract
- View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system

- Abstract
- Der Arbeitsbericht befasst sich mit den zwei unterschiedlichen Usability Methoden, dem Usability Test und den Usability Inspektionsmethoden. Bei den Usability Inspektionsmethoden wird die Benutzungsschnittstelle durch Ergonomieexperten evaluiert. Diese Methoden umfassen die Heuristische Evaluation, standard inspection und cognitive walkthrough, etc. Der Vorteil dieser Inspektionsmethoden liegt darin, dass sie weniger zeitintensiv und kostengünstiger als ein Usability Test sind. Der Usability Test wird im Gegensatz zu den Usability Inspektionsmethoden mit repräsentativen Versuchspersonen durchgeführt. Er ist ein effizientes Mittel um Benutzungsschnittstellen zu evaluieren oder auf deren Benutzungsfreundlichkeit zu überprüfen. Des weiteren erläutert der Arbeitsbericht die verschiedenen Usability Testmethoden sowie die Basiselemente zur Durchführung eines Usability Tests. Abschließend wird noch auf die Varianzanalyse (Analysis of Variance, ANOVA) als ein statistisches Verfahren zur Überprüfung von Mittelwertsunterschieden näher eingegangen.
