- "Die Recherche im "klassischen" OPAC verlangt eine exakte Formulierung der Suchanfrage, aber viele Bibliotheksbenutzer wissen nicht genau, wonach sie eigentlich suchen. So bleiben oft wertvolle Treffer oder sogar Teile des Bibliotheksbestandes von den Bibliotheksbenutzern unentdeckt. Ein neues Produkt in der Angebotspalette des Bibliothekssoftware-Herstellers BOND GmbH & Co. KG schafft Abhilfe: Der AquaBrowser Library. Er sprengt die Grenzen der konventionellen OPAC-Suche und bietet ein neues, "ergonomisches" Sucherlebnis: die erste progressive und interaktive Suchumgebung. AquaBrowser Library bezieht in die OPAC-Suche automatisch assoziative Begriffe, Synonyme, unterschiedliche Schreibweisen, Übersetzungen sowie den Kontext mit ein. So werden automatisch neue Suchpfade generiert, der Suchbereich und somit auch das Trefferspektrum erweitert. Als Ergebnis erhält der Informationssuchende eine umfangreichere und qualitativ präzisere Ergebnisliste. Das Suchergebnis geht weit über eine Suchliste hinaus: Der Suchbegriff eines Benutzers wird mit den im Bibliothekskatalog enthaltenen Metadaten verglichen. Dabei werden assoziative Begriffe, Synonyme, alternative Schreibweisen, Übersetzungen in Fremdsprachen sowie der Kontext mit einbezogen. Daraus generiert sich automatisch eine visuelle Karte, die so genannte "Word Cloud". Sie stellt alle Assoziationen oder Überblicke über interessante Themenbereiche grafisch logisch dar. Die Begriffe sind Vorschläge und Hilfestellungen für den Bibliotheksbenutzer. Per Klick auf die "Word Cloud" kann er so neue Informationen entdecken und seine Suchanfrage präzisieren und lenken. Beispielsweise werden Tippfehler erkannt und alternative Schreibweisen angeboten. Gibt ein Leser den Suchbegriff "Auto" ein, beinhaltet das Suchergebnis auch Medien zu "PKW", "Kraftfahrzeug" oder "KFZ". Es werden sogar Treffer angezeigt, bei denen der gesuchte Begriff in einer anderen Sprache (englisch, spanisch oder niederländisch) im Katalogisat hinterlegt ist (z.B. car). Bei jeder Suchabfrage erstellt AquaBrowser Library automatisch eine Liste relevanter Kriterien, nach denen der Benutzer seine Ergebnisse filtern kann. Ein Klick auf ein Kriterium genügt und schon werden die Suchergebnisse präzisiert. Auf diese Weise schränken Mediensuchende die Treffer zielgenau ein und gelangen so schnell und exakt zu der spezifischen Information, die sie brauchen. Die Verfeinerungskriterien sind übersichtlich anhand von Kategorien gegliedert (z.B. Schlagwort, Verfasser, Sprache, Personen, Thema, Reihe oder Jahr)."

- Abstract
- Reports on the design of a GUI for the Okapi 'best match' retrieval system developed at the Centre for Interactive Systems Research, City University, UK, for online library catalogues. The X-Windows interface includes an interactive query expansion (IQE) facilty which involves the user in the selection of query terms to reformulate a search. Presents the design rationale, based on a game board metaphor, and describes the features of each of the stages of the search interaction. Reports on the early operational field trial and discusses relevant evaluation issues and objectives

- Abstract
- Faceted navigation is already a standard feature of contemporary Online Public Access Catalogs (OPACs). The article aims to indicate practices in this area and new affordances that faceted navigation provides. The content of 55 Polish university library websites and their OPACs using faceted navigation was analyzed. After selecting the subject facets, the source of the terms constituting their content was analyzed using the MARC 21 bibliographic record format structure. During the transfer of traditional KOS affordances to those of faceted navigation, the former knowledge organization (KO) structures were deconstructed, which may require the creation of a new kind of KOS.

- Abstract
- The Online Public Access Catalog (OPAC) is an information retrieval system characterized by short bibliographic records, mainly of books, journals, and audiovisual materials available in a particular library. This, coupled with a Boolean search interface and a heterogeneous user population with diverse needs, presents special problems for subject searching by end users. To perform effective subject searching in the OPAC system requires a wide range of knowledge and skills. Various approaches to improving the OPAC design for subject searching have been proposed and are reviewed in this entry. The trend toward Web-based OPAC interfaces and the developments in Internet and digital library technologies present fresh opportunities for enhancing the effectiveness of the OPAC system for subject searching.

- Abstract
- An online library catalogue served as a testbed to evaluate an interactive query expansion facility based on relevance feedback for the Okapi probabilistic term weighting retrieval system. The facility was implemented in a graphical user interface (GUI) environment using a game-board metaphor for the search process, and allowed searchers to select candidate terms extracted from relevant retrieved itms to reformulate queries. The take-up of the interactive query expansion option was found to be lower, and its retrieval performance less effective, compared to previous tests featuring automatic query expansion. Contributory factors including the number, presentation and source of terms are discussed

- Abstract
- Describes the OKAPI projects and OKAPI's development as an experimental online catalogue system over 10 years, first at the University of Westminster (formerly the Polytechnique of Central London) and subsequently at City University, London. The 1st OKAPI project in 1984 introduced 'best match' retrieval and focused on the user interface design. The 2nd investigated word stemming, spelling correction and cross reference tables as retrieval aids. A comparative study of 2 library catalogues was undertaken in 1987, while in 1988 query expansion and relevance feedback were introduced and evaluated by laboratory tests. In 1990 live evaluation of automatic query expansion was carried out and in 1993 subject enhancement of bibliographic records was investigated. The latest project has examined the design of a graphical user interface to support interactive query expansion. Discusses the research and evaluation of each project

- Abstract
- Presents a brief report on a study, carried out by the Centre for Interactive Systems Research, City University, to investigate the techniques used for evaluating OPACs: to explore and assess different data gathering methods in studying information seeking behaviour at the on-line catalogue; and to examine how a transaction logging facility could be enhanced to serve as a more effective diagnostic tool.

- Abstract
- Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system
