Abstract

Compares and contrasts online searching on DataStar using the 'classic' command language, with access via the more recent Web interface (DataStar Web). The search functionality of the 2 interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike

Abstract

Ovid has supported a sophisticated interface for searching bibliographic and full text databases for some time. It is now offering a Web based version of this interface that is capable of accessing Z39.50-compliant OPACs and databases anywhere in the world. The Ovid Web Gateway builds on the Ovid Server, thus allowing for a variety of functions and configurations at user, group and database-specific level. The Web Gateway has a selection of download formats and delivery options

Abstract

Reviews STN Easy, a Web service that provides access to 2 dozen leading sci-tech databases which is produced jointly by the Chemical Abstracts Service of the American Chemical Society, Germany's FIZ-Karlsruhe, and Japan' SCience and Technology Corporation. It employs a graphical interface, relevance searching, and output based pricing. STN Easy is STN's solution for members of the technical community and others who are not users of the main STN service. The databases included the leading files in STN's major subject areas namely: SCISEARCH; Mathematics Abstracts; MEDLINE; EMBASE; BIOSIS; COMPENDEX; INSPEC; Worlds Patent Index; Inpadoc; US Patents Fulltext; PROMPT; and Chemical & Engineering News. Discusses searching; pricing; and the pros and cons of end user searching

Abstract

EBSCO Publishing have demonstrated a beta version of EBSCOhost, version 3.0, which includes several new features that enrich searching, enhance result lists and make general navigation into and out of the search interface easier. Features unclude: simultaneous multiple database searching; hierarchical authority files; and additional authority file searching options; including a relevancy ranked 'find more like' feature

Abstract

Describes the coming together of 2 independent user interface softwares for improving access to databases: MenUSE (Menu-based User Search Engine) and HIBROWSE (High Resolution Interface for Database Specific BROWsing and SEarching). MenUSE was developed for searching bibliographic databases whilst HIBROWSE is a front end for searching information stored on structured relational database management systems. Combining these 2 approaches affords users much greater access capabilities than is possible using traditional information retrieval systems. Describes the power of HIBROWSE in the context of EPOQUE (the European Parliament Online QUEry system) and the INSPEC database

Abstract

The searching behaviour of 79 end-users of CD-ROM databases was studied at the UCLA campus libraries. The results indicate that users lack basic knowledge on how to search and consequently their searches are not effective despite their efforts. Users therefore need help through training but most importantly by improving the CD-ROM user interfaces and retrieval systems

Abstract

STN Easy is a new graphic user interface for the WWW access to over 20 major online databases in business, science, technology and patents. Patent information is available from a number of Web sites but argues that STN Easy offers extensive coverage combined with both searching sophistication and operational simplicity. Concludes that STN Easy is not a replacement for nor competitor to STN, but provides a complementary means of retrieving patent information for end users or others who do not need the full power of a command language

Abstract

Current user interfaces for textual database searching leave much to be desired: individually, they are often confusing, and as a group, they are seriously inconsistent. We propose a four- phase framework for user-interface design: the framework provides common structure and terminology for searching while preserving the distinct features of individual collections and search mechanisms. Users will benefit from faster learning, increased comprehension, and better control, leading to more effective searches and higher satisfaction.

Abstract

Demonstrates that a mode of interaction, analogous to the optomechanical principles applied in the Peek-a-Boo system, can be applied in computerized retrieval systems to enhance the quality of human-computer interaction radically and increase effectiveness. The MenUSE (Menu based User Search Engine) software has evolved from constructing explicit Boolean combinations of concepts automatically to using an implicit Boolean searching approach, similar to Peek-a-Boo. Thesauri and classification schemes, together with other searchable values, provide the user with views of a database and a means for the recognition and selection of concepts and other parameters by the end user. The resulting filtering model has been implemented for searching the European Parliament's EPOQUE database and for INSPEC. This second application provides illustrations of the technique for this paper

Abstract

Presents a chart comparing the subject access features available on 4 different catalogues (card catalogues, GEAC, MELVYL and NOTIS) and develops a method for 'walking through' subject searches in different catalogues using a 'naive subject searcher' model in which searching behaviour is determined by 3 basic characteristics: a lack of understanding of how information is stored, indexed, and retrieved in library catalogues; a preference for the simplest available mode of interaction with the catalogue and a lack of any searching strategy or tactics beyond simple 'subject searching'. A complete 'naive Subject search' of the GEAC 8000-based GLIS on-line catalogue is presented, and sample NOTIS and MELVYL screens are discussed

Abstract

The application of classification schemes and thesauri to improve online information retrieval can be traced back to the beginnings of online searching itself, but the true potential for using knowledge structures in the user interface has yet to be realized. View-based searching seeks to exploit the classified arrangements in thesauri and existing classification schemes to improve the performance of such systems. HIBROWSE for EMBASE is a system which demonstrates the power of applying an approach to information retrieval which is strongly related to faceted classification. It does this by employing a point a click user interface with mutually constraining views utilising knowledge structure hierarchies for both query specification and the presentation of results. The relevance of this approach to library OPACs is discussed in the context of the digital library, concluding that out legacy of research in classification and indexing is more relevant than ever in the design of systems to cope with the problems of information access

Abstract

View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system
