Abstract

This article revisits the debate concerning controlled and natural indexing languages, as used in searching the databases of the online hosts, in-house information retrieval systems, online public access catalogues and databases stored on CD-ROM. The debate was first formulated in the early days of information retrieval more than a century ago but, despite significant advance in technology, remains unresolved. The article divides the history of the debate into four eras. Era one was characterised by the introduction of controlled vocabulary. Era two focused on comparisons between different indexing languages in order to assess which was best. Era three saw a number of case studies of limited generalisability and a general recognition that the best search performance can be achieved by the parallel use of the two types of indexing languages. The emphasis in Era four has been on the development of end-user-based systems, including online public access catalogues and databases on CD-ROM. Recent developments in the use of expert systems techniques to support the representation of meaning may lead to systems which offer significant support to the user in end-user searching. In the meantime, however, information retrieval in practice involves a mixture of natural and controlled indexing languages used to search a wide variety of different kinds of databases

Abstract

All information systems should contribute to the competitive position of an organization and should therefore be strategic. Strategic Information Systems Planning (SISP) is the process of establishing a programme for the implementation and use of information systems so theat the effectiveness of the firm's information resources are optimized and used to support the objectives of the organization as much as possible. SISP involves matching computer applications with the objectives and corporate strategy of the organization. Starts by exploring the nature of a strategic information system and then process to outline the basic steps and features of an SISP. Reviews the criteria to be applied in the selection of an SISP

Abstract

The study sets out to explore the factors that influence the evaluation of information and the judgments made in the process of finding useful information in web search contexts. Based on a diary study of 2 assigned tasks to search on Google and Google Scholar, factor analysis identified the core constructs of content, relevance, scope, and style, as well as informational and system "ease of use" as influencing the judgment that useful information had been found. Differences were found in the participants' evaluation of information across the search tasks on Google and on Google Scholar when identified by the factors related to both content and ease of use. The findings from this study suggest how searchers might critically evaluate information, and the study identifies a relation between the user's involvement in the information interaction and the influences of the perceived system ease of use and information design.

Abstract

Purpose - The purpose of this paper is to propose a multi-dimensional taxonomy for information kiosk-based self service technologies (SSTs). This taxonomy has an important contribution to make to the integration of research and development, in relation to information kiosks. There are aspects that may also be extended to e-service, online service and self-service. Design/methodology/approach - The conceptual context for this work is established by a review of previous literature. This focuses on taxonomies and classification schemes relating to information kiosks, traditional services (p-services) and e-services. A comprehensive database of information kiosk technologies and their applications is constructed. Longitudinal observation of the development of information kiosk technologies is the basis for this and has been extended by web research. Findings - An iterative analysis of the kiosk database defines the nature of service delivery from kiosks, and supports the identification and verification of the dimensions and sub-dimensions of the taxonomy. It is informed by earlier classification schemes and taxonomies in the information kiosk, e-service and p-service literature. Originality/value - This taxonomy has four main dimensions: Location, User, Task and Technology. Sub-dimensions are developed for each of these main dimensions. It can be used to classify all information kiosks.
