Abstract

In principle, the 'knowledge' encoded in a thesaurus can be exploited in many ways to help users clarify their information needs and enhance query performance, but attempts to automate this process via AI techniques face many practical difficulties. In the short term it may be more useful to improve support for direct interactive use of thesauri. We discuss some of the issues which have arisen when building an interface for thesaurus navigation and query enhancement, drawing on logs and user feedback from ongoing small-scale experiments

Abstract

Human Information Behavior (HIB) research commonly examines behavior in the context of why information is acquired and how it will be used, but usually at the level of the work or everyday-life tasks the information will support. HIB has not been examined in detail at the broader contextual level of intellectual purpose (that is, the higher-order conceptual tasks the information was acquired to support). Examination at this level can enhance holistic understanding of HIB as a "means to an intellectual end" and inform the design of digital information environments that support information interaction for specific intellectual purposes. We investigate information-based ideation (IBI) as a specific intellectual information acquisition and use context by conducting Critical Incident-style interviews with 10 game designers, focusing on how they interact with information to generate and develop creative design ideas. Our findings give rise to a framework of their ideation-focused HIB, which systems designers can leverage to reason about how best to support certain behaviors to drive design ideation. These findings emphasize the importance of intellectual purpose as a driver for acquisition and desired outcome of use.

Abstract

This paper demonstrates the application of conventional database design techniques to thesaurus representation. The thesaurus is considered as a printed document, as a semantic net, and as a relational database to be used in conjunction with an intelligent information retrieval system. Some issues raised by analysis of two standard thesauri include: the prevalence of compound terms and the representation of term structure; thesaurus redundancy and the extent to which it can be eliminated in machine-readable versions; the difficulty of exploiting thesaurus knowledge originally designed for human rather than automatic interpretation; deriving 'strength of association' measures between terms in a thesaurus considered as a semantic net; facet representation and the need for variations in the data model to cater for structural differences between thesauri. A complete schema of database tables is presented, with an outline suggestion for using the stored information when matching one or more thesaurus terms with a user's query

Abstract

In meinem Buch CyberSociety: Computer-Mediated Communication and Community habe ich Begriffe, die gewöhnlich dazu gebraucht werden, um das Internet zu beschreiben, als unglücklich gewählte Metaphern kritisiert - so wie in den USA »Information Highway« und »National Information Infrastructure«. Sie sind unglücklich, weil sie viel intellektuellen und sozialen Ballast mit sich tragen, den sie sich durch verblüffende Parallelen zwischen dem gegenwärtigen Projekt des »Information Superhighway« und dem Highway-Projekt aufladen, das in Amerika zur Zeit der Weltkriege durchgeführt wurde - wie etwa das Vertrauen in das Wort »Highway« und seine romantische Konnotation der freien Fahrt. Eine andere wichtige Parallele ist die zwischen dem ursprünglich militärisch motivierten Bau von Autobahnen (die bereits auf Thomas Jefferson zurückgeht) und den militärischen Ursprüngen des prominentesten Informationsnetzes, des Internet, in dem das Computernetzwerk des Verteidigungsministeriums mit den Forschungszentren der Universitäten verbunden worden ist. Schließlich besteht eine weitere Parallele zwischen dem »Weltraumwettrennen« der sechziger Jahre und unserem anhaltenden Streben, bei neuen Technologien und Wissenschaften führend zu sein.

Abstract

Explores interface design raised by the development and evaluation of Okapi, a highly interactive information retrieval system based on a probabilistic retrieval model with relevance feedback. It uses terms frequency weighting functions to display retrieved items in a best match ranked order; it can also find additional items similar to those marked as relevant by the searcher. Compares the effectiveness of automatic and interactive query expansion in different user interface environments. focuses on the nature of interaction in information retrieval and the interrelationship between functional visibility, the user's cognitive loading and the balance of control between user and system

Abstract

Describes the evolution and some of the functions of the layers of complex software which lie between the basic formula at the heart of the Okapi information retrieval system and the simple interface which it presents to the user. Addresses some possible approaches to the goal of easy system configurability, a goal which can be at odds with the desire to build a fully integrated package. Considers some of the issues to be faced in moving Okapi to the WWW, client server, distributed processing environment

Abstract

Reports on work in progress to define an object oriented model of a probabilistic information retrieval system (OKAPI), the central component of which is the query itself. Considers how to represent queries both internally and at the user interface level, and their relationship with other components of the model. The model will form the basis of a configurable user interface, which allows controlled experiments to be undertaken, and could be adapted to the needs of different users accessing different databases. Implementation will involve the use of a high level interpreted scripting language for overall control, communicating with an internal model and an interface model, designed and developed using object oriented techniques
