- 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
- A new search paradigm, in which the primary user activity is the guided exploration of a complex information space rather than the retrieval of items based on precise specifications, is proposed. The author claims that this paradigm is the norm in most practical applications, and that solutions based on traditional search methods are not effective in this context. He then presents a solution based on dynamic taxonomies, a knowledge management model that effectively guides users to reach their goal while giving them total freedom in exploring the information base. Applications, benefits, and current research are discussed.

- Abstract
- "Ergonomisch" suchen! Ähnlich wie beim Surfen durch Webseiten, so navigiert der Leser mit SpiderSearch per Mausklick durch den Medienbestand der Bibliothek und erschließt diesen damit spielerisch. Wie kann man sich das vorstellen? SpiderSearch ist ein Zusatzmodul zum bewährten BOND-WebOPAC. Der Benutzer gibt, wie im normalen WebOPAC, sein gesuchtes Stichwort ein. Sofort setzt SpiderSearch den Begriff in das Zentrum einer grafischen Ergebnisoberfläche. Gleichzeitig bereitet SpiderSearch ein "semantisches Netz" mit "sinnvollen" Begriffen für die weitere Suche auf und stellt diese dem Leser in animierter visuell ansprechender Form zur Verfügung. Diese Begriffe (Assoziative) sind auf unterschiedliche Arten mit dem gesuchten Zentralbegriff verwandt. Sei es eine Wortverwandtschaft wie "Bibliothek" und "Bibliothekarin", eine Sinnverwandtschaft wie "Bibliothek" und "lesen" oder ein anderer sprachwissenschaftlicher Zusammenhang wie z.B. "Bibliothek" und "Ruhe". Die unterschiedlichen Verwandtschaftsarten werden durch unterschiedliche Farben und Größen deutlich. Zum Verfeinern kann der Benutzer einfach einen der verwandten Begriffe anklicken und die Suche wird um diesen Suchbegriff erweitert. So wird der Leser in seiner weiteren Suche quasi durch dieses "Netz" geführt. Eine revolutionäre Art der Suche, mit der die Bibliotheksbenutzer ihre eigenen Informationsnetze spinnen und einfach und sehr anschaulich den Medienbestand noch optimaler erschließen können.

- Abstract
- The digital library system Daffodil is targeted at strategic support of users during the information search process. For searching, exploring and managing digital library objects it provides user-customisable information seeking patterns over a federation of heterogeneous digital libraries. In this paper evaluation results with respect to retrieval effectiveness, efficiency and user satisfaction are presented. The analysis focuses on strategic support for the scientific work-flow. Daffodil supports the whole work-flow, from data source selection over information seeking to the representation, organisation and reuse of information. By embedding high level search functionality into the scientific work-flow, the user experiences better strategic system support due to a more systematic work process. These ideas have been implemented in Daffodil followed by a qualitative evaluation. The evaluation has been conducted with 28 participants, ranging from information seeking novices to experts. The results are promising, as they support the chosen model.

- Abstract
- Der Hersteller von Bibliothekssoftware BOND erweitert sein Produktangebot um eine innovative Neuheit, den Assoziativ-OPAC SpiderSearch. Dieser graphische Web-OPAC sucht zu einem Stichwort Assoziative, d.h. sinn- oder sprachwissenschaftlich verwandte Begriffe. Diese baut er spinnennetzartig um den zentralen Suchbegriff herum auf. Anhand der ihm angebotenen Assoziative kann sich der Leser sehr einfach und anschaulich durch den Medienbestand der Bibliothek klicken. So findet er schnell und komfortabel relevante Medien, die mit herkömmlichen Suchverfahren nur schwer recherchierbar wären. Mühsame Überlegungen über verwandte Suchbegriffe und angrenzende Themengebiete bleiben dem Benutzer erspart. Dies übernimmt SpiderSearch und navigiert den Benutzer ähnlich wie beim Surfen durch Webseiten durch sämtliche Themen, die mit dem Suchbegriff in Zusammenhang stehen. Auch aufwändiges Durchblättern einer riesigen Suchergebnisliste ist nicht nötig. Durch die im semantischen Netz vorgeschlagenen Begriffe, kann der Benutzer sein Thema genau eingrenzen und erhält in seiner Trefferliste nur passende Medien. Diese ordnet SpiderSearch nach ihrer Relevanz, so dass der Leser die benötigte Literatur einfach und komfortabel findet. Wie auch im normalen Web-OPAC enthält die Trefferliste Angaben zu Titel, Standort und Verfügbarkeit des Mediums. Zur einfachen Zuordnung der Medienart ist jedem Medium ein entsprechendes Symbol zugewiesen. Per Mausklick erhält der Benutzer Detailangaben zum Medium und optional eine Ansicht des Buchcovers. SpiderSearch ist ein Zusatzmodul zur Software BIBLIOTHECA2000 von BOND und setzt auf den Web-OPAL auf. Vor allem bei Öffentlichen Bibliotheken stößt SpiderSearch auf großes Interesse. Erste Anwender bieten Ihren Lesern bereits dieses neue Sucherlebnis.

- Abstract
- Humans can make hasty, but generally robust judgements about what a text fragment is, or is not, about. Such judgements are termed information inference. This article furnishes an account of information inference from a psychologistic stance. By drawing an theories from nonclassical logic and applied cognition, an information inference mechanism is proposed that makes inferences via computations of information flow through an approximation of a conceptual space. Within a conceptual space information is represented geometrically. In this article, geometric representations of words are realized as vectors in a high dimensional semantic space, which is automatically constructed from a text corpus. Two approaches were presented for priming vector representations according to context. The first approach uses a concept combination heuristic to adjust the vector representation of a concept in the light of the representation of another concept. The second approach computes a prototypical concept an the basis of exemplar trace texts and moves it in the dimensional space according to the context. Information inference is evaluated by measuring the effectiveness of query models derived by information flow computations. Results show that information flow contributes significantly to query model effectiveness, particularly with respect to precision. Moreover, retrieval effectiveness compares favorably with two probabilistic query models, and another based an semantic association. More generally, this article can be seen as a contribution towards realizing operational systems that mimic text-based human reasoning.
