- Abstract
- Keyword based querying has been an immediate and efficient way to specify and retrieve related information that the user inquired. However, conventional document ranking based on an automatic assessment of document relevance to the query may not be the best approach when little information is given. Proposes an idea to integrate 2 existing techniques, query expansion and relevance feedback to achieve a concept-based information search for the Web

- Abstract
- Host-Retrieval und Global Research war das Thema der 20. Online-Tagung der DGD im Mai 1998. Erfahrungen und Einschätzungen von mehr als 60 Referentinnen und Referenten zu Fragen der kommerziellen sowie der innerbetrieblichen Informationsrecherche, zum internationalen Informationsangebot, zur Informationsvermittlung mit neuen Ansätzen, zur Geschäftsabwicklung über das Internet oder zur Informationsbeschaffung in den Bereichen Chemie, Pharma, Biologie, Medizin, Patente und Wirtschaft erwarteten die Kongreßbesucher. Der Tagungsband vereinigt über 30 der dort gehaltenen Vorträge. Es wird der Bogen gespannt von der Informationsbereitstellung in klassischen gut erschlossenen und aufbereiteten Informationsdatenbanken bis hin zu tagesaktueller Verbrauchsinformation im WWW. Das Thema digitale Bibliotheken wird ebenso behandelt wie neue Verfahren des Wissensmanagements in Unternehmen und Suchmaschinen im WWW

- Abstract
- Describes the shortcomings of search engines for the WWW comparing their current capabilities to those of the first generation CD-ROM products. Some allow phrase searching and most are improving their Boolean searching. Few allow truncation, wild cards or nested logic. They are stateless, losing previous search criteria. Unlike the indexing and classification systems for today's CD-ROMs, those for Web pages are random, unstructured and of variable quality. Considers that at best Web search engines can only offer free text searching. Discusses whether automatic data classification systems such as Infoseek Ultra can overcome the haphazard nature of the Web with neural network technology, and whether Boolean search techniques may be redundant when replaced by technology such as the Euroferret search engine. However, artificial intelligence is rarely successful on huge, varied databases. Relevance ranking and automatic query expansion still use the same simple inverted indexes. Most Web search engines do nothing more than word counting. Further complications arise with foreign languages

- 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
- This reviews looks briefly at the history of WWW search engine development, considers the current state of affairs, and reflects on the future. Networked discovery tools have evolved along with Internet resource availability. WWW search engines display some complexity in their variety, content, resource acquisition strategies, and in the array of tools the deploy to assist users. A small but growing body of evaluation literature, much of it not systematic in nature, indicates that performance effectiveness is difficult to assess in this setting. Significant improvements in general-content search engine retrieval and ranking performance may not be possible, and are probalby not worth the effort, although search engine providers have introduced some rudimentary attempts at personalization, summarization, and query expansion. The shift to distributed search across multitype database systems could extend general networked discovery and retrieval to include smaller resource collections with rich metadata and navigation tools

- Abstract
- Discusses the ways in which systems and/or users formulate and reformulate searches in documents retrieval systems (DRS), database management systems (DBMS) and expert systems (ES). Concludes that query formulation and reformulation has been neglected in these fields

- Abstract
- Die Ergebnisse automatischen Indexierens nach Worthäufigkeit werden in verschiedenen Varianten gezeigt. Zuerst werden die Textwörter mit einer fortlaufenden Numerierung maschinell selegiert, dann alphabetisch sortiert mit Häufigkeitsangaben. Durch die Bildung von Quasi-Stämmen läßt eine Frequenzliste dominierende Fachgebiete erkennen. Danach wird noch eine Ordnung nach Begriffen vorgeführt. Sie zeigt, wie man beim Retrieval hohe Vollständigkeits- oder hohe Genauigkeitsraten erzielen kann

- Abstract
- Evaluates the retrieval effectiveness of query expansion strategies on a test collection of the medical database MEDLINE using Cornell University's SMART retrieval system. Tests 3 expansion strategies for their ability to identify appropriate MeSH terms for user queries. Compares retrieval effectiveness using the original unexpanded and the alternative expanded user queries on a collection of 75 queries and 2.334 Medline citations. Recommends query expansions using retrieval feedback for adding MeSH search terms to a user's initial query
