- 1. Introduction Web search engines and digital libraries usually expect the users to use search terms that most accurately represent their information needs. Finding the most appropriate search terms to represent an information need is an age old problem in information retrieval. Keyword or phrase search may produce good search results as long as the search terms or phrase(s) match those used by the authors and have been chosen for indexing by the concerned information retrieval system. Since this does not always happen, a large number of false drops are produced by information retrieval systems. The retrieval results become worse in very large systems that deal with millions of records, such as the Web search engines and digital libraries. Vocabulary control tools are used to improve the performance of text retrieval systems. Thesauri, the most common type of vocabulary control tool used in information retrieval, appeared in the late fifties, designed for use with the emerging post-coordinate indexing systems of that time. They are used to exert terminology control in indexing, and to aid in searching by allowing the searcher to select appropriate search terms. A large volume of literature exists describing the design features, and experiments with the use, of thesauri in various types of information retrieval systems (see for example, Furnas et.al., 1987; Bates, 1986, 1998; Milstead, 1997, and Shiri et al., 2002).

- Abstract
- Bei webbasierten Suchmaschinen werden zunehmend auch Systeme mit Visualisierungskomponenten für die Ergebnisrepräsentation angeboten. Die Ansätze der Visualisierungen unterscheiden sich hierbei in der Zielsetzung und Ausführung deutlich voneinander. Der folgende Beitrag beschreibt die verwendeten Visualisierungsmethoden, systematisiert diese anhand einer Klassifikation, stellt die führenden frei zugänglichen Systeme vor und vergleicht diese anhand der Kriterien aus der Systematisierung. Die typischen Problemfelder werden identifiziert und die wichtigsten Gemeinsamkeiten und Unterschiede der untersuchten Systeme herausgearbeitet. Die Vorstellung zweier innovativer Visualisierungskonzepte im Bereich der Relationenvisualisierung innerhalb von Treffermengen und der Visualisierung von Relationen bei der Suche nach Musik schließen den Beitrag ab.

- The aim of this study is to develop a software tool, VisuaLCSH, for effective searching, browsing, and maintenance of LCSH. This tool enables visualizing subject headings and hierarchical structures implied and embedded in LCSH. A conceptual framework for converting the hierarchical structure of headings in LCSH to an explicit tree structure is proposed, described, and implemented. The highlights of VisuaLCSH are summarized below: 1) revealing multiple aspects of a heading; 2) normalizing the hierarchical relationships in LCSH; 3) showing multi-level hierarchies in LCSH sub-trees; 4) improving the navigational function of LCSH in retrieval; and 5) enabling the implementation of generic search, i.e., the 'exploding' feature, in searching LCSH.
