Geographical context is required of many information retrieval tasks in which the target of the search may(More)
This paper reports an in-depth case study of a rapid application development (RAD) project. RAD is a recent information systems development method noted for its high levels of user involvement and use of iterative prototyping. The paper develops a model of the core features of RAD gleaned from literature such as that published on the dynamic systems(More)
This paper discusses issues concerning the augmentation of thesaurus relationships, in light of new application possibilities for retrieval. We first discuss a case study that explored the retrieval potential of an augmented set of thesaurus relationships by specialising standard relationships into richer subtypes, in particular hierarchical geographical(More)
Gazeteers and geographical thesauri can be regarded as parsimonious spatial models that associate geographical location with place names and encode some semantic relations between the names. They are of particular value in processing information retrieval requests in which the user employs place names to specify geographical context. Typically the geometric(More)
This paper discusses an approach to navigation based on queries made possible by a semantic hypermedia architecture. Navigation via query offers an augmented browsing capacity based on measures of semantic closeness between terms in an index space that models the classification of artefacts within a museum collection management system. The paper discusses(More)
This paper explores the consequences of the uncertainty introduced into the system development lifecycle by a prototyping approach and the practical strategies employed by developers in prototyping projects. Drawing on various strands of the sociology of technology, the paper discusses findings from a multidisciplinary research project, which investigated(More)
