- Abstract
- The Konstanz-Hypertext-System (KHS) is an open hypertext system which employs internal and external information sources to satisfy the user's need for information when navigating through a hypertext. E-mail, Gopher and online databases are available in KHS as external information sources. The main tasks which must be carried out during an online search are analysis of the question, selection of the databases, formulation of a search strategy, online search, feedback and the presentation of the results. All of these tasks are supported within KHS, but special emphasis is given to database selection. Introduces a new method for selecting relevant online databases with KHS using the database descriptions from several hosts

- Abstract
- Investigates how linkage environments in a hypertext based bibliographic retrieval system affect retrieval performance for novice and experienced searchers, 2 systems, 1 with inter record linkages to authors and descriptors and 1 that also included title and abstract keywords, were tested. No significant differences in retrieval performance and system usage were found for most search tests. The enhanced system did provide better performance where title and abstract keywords provided the most direct access to relevant records. The findings have implications for the design of bilbiographic information retrieval systems using hypertext linkages

- Abstract
- The aim of probabilistic models is to define a retrieval strategy within which documents can be optimally ranked according to their relevance probability with respect to a given request. Presents a study which suggests representing documents not only by index term vendors, as proposed by previous probabilistic models but also by considering relevance hypertext links. To enhance retrieval effectiveness, the learning retrieval scheme should modify the weight assigned to each indexing terms, the importance attached to each search term, and the relationships between documents. Evaluation of the proposed retrieval scheme with a hypertext based on the CACM test collection which includes 3.204 documents and the CISI corpus (1,460 documents), yields interesting results on the retrieval effectiveness of this approach

- Abstract
- Hypertext for multi-media and full-text documents is rapidly developed on all fronts. For bibliographic information retrieval the applications are promising but pose several difficulties. Describes work conducted at the School of Library and Information Science at Univ. of Western Ontario the objective of which is to add the capability of a browsing search to an existing OPAC through the use of Windowed Hypertext Interface for Zippy Retrieval and Display (WHIZRD) software. Discusses the underlying retrieval capabilities of the system. Examines design problems and solutions and outlines future enhancements

- Abstract
- In most hypertext systems, information retrieval techniques emphasize browsing or navigational methods which are not thorough enough to find all relevant material, especially when the number of nodes and/or links becomes very large. Reviews the main query-based search techniques currently used in hypertext environments. Explains the experimental methodology. Concentrates on the retrieval effectiveness of these retrieval strategies. Considers ways of improving search effectiveness

- Abstract
- In proposing a searching strategy well suited to the hypertext environment, we have considered four criteria: (1) the retrieval scheme should be integrated into a large hypertext environment; (2) the retrieval process should be operable with an unrestricted text collection; (3) the processing time should be reasonable; and (4) the system should be capable of learning in order to improve its retrieval effectiveness

- Abstract
- Introduces what automatic authoring of a hypertext for information retrieval means. The most difficult part of the automatic construction of a hypertext is the creation of links connecting documents or document fragments that are related. Becaus of this, to many researchers it seemed natural to use information retrieval techniques for this purpose, since information retrieval has always dealt with the construction of relationships between objects mutually relevant. Presents a survey of some of the attempts toward the automatic construction of hypertexts for information retrieval. Identifies and compares scope, advantages and limitations of different approaches. Points out the main and most successful current lines of research

- Abstract
- Discusses the decision points and major implementation steps for deploying a client server full text image retrieval system within a large aerospace manufactoring organisation. The changes in interface brought about by moving from workstation platform to client server, and combining a controlled vocabulary data base with a full text data base are described
