Abstract: The BOOK HOUSE system is an example of a system for fiction retrieval, where the structure of the work domain is represented by a metaphor familiar to users, which provides the proper associations for the information retrieval task. It presents for users a coherent display of a complex, rich information context within which they can navigate freely without being constrained by the system. It is intended to support retrieval and decision making of fiction retrieval in both familiar, ambigous and problematic situations for casual, novice end users, to whom it provides the capability of visual exploration of icons and direct perception and manipulation of the iconic objects of the artificial, but familiar, environment of the BOOK HOUSE

Abstract

Decribes the BookHouse, a system for the retrieval and indexing of fiction and non fiction literature developed for public and school libraries though cooperation between library and information science professionals. Discusses 3 aspects of the system: domain characteristic; task analysis; and user characteristics. Outlines the framework underlying the collection of field data with special emphasis on the work involved in transforming the empirical field studies of user behaviour in the library into computer system specifications and subsequent design of a retrieval system providing subject access to fiction. Describes a few of the many indexing policies, rules and practices which evolved for concept identification and book descriptions as well as the functionality and associated displays of the system for supporting the retrieval and indexing of fiction

Abstract

Information retrieval and exploration of work domains through databases and integrated information systems has become increasingly important in many modern work settings (as well as in libraries). The problem space of the users is defined on occasion by the dynamically changing requirements from their tasks and goals. it is argued that IR system design should be based on an analysis of the properties of the work domain, the task situation and the user characteristics. The paper describes a general framework for IR system design that has been used in the design of a library system. A special problem identified from use of the framework in domain analysis of fiction retrieval is treated in more detail: mapping the authors' domain structures to the domain structures expressed in users' needs in indexing and representation of fiction

Abstract

This paper describes the Book House system which is designed to support children's information retrieval in libraries as part of their education. It is a shareware program available on CD-ROM and discs, and comprises functionality for database searching as well as for the classification and storage of book information in the database. The system concept is based on an understanding of children's domain structures and their capabilities for categorization of information needs in connection with their activities in public libraries, in school libraries or in schools. These structures are visualized in the interface by using metaphors and multimedia technology. Through the use of text, images and animation, the Book House supports children - even at a very early age - to learn by doing in an enjoyable way which plays on their previous experiences with computer games. Both words and pictures can be used for searching; this makes the system suitable for all age groups. Even children who have not yet learned to read properly can by selecting pictures search for and find books they would like to have read aloud. Thus at the very beginning of their school period, they can learn to search for books on their own. For the library community itself, such a system will provide an extended service which will increase the number of children's own searches and also improve the relevance, quality and utilization of the collections in the libraries. A market research on the need for an annual indexing service for books in the Book House format is in preparation by the Danish Library Center

Abstract

This paper describes a new OPAC system called The Book House and discusses its relevance as a solution to current OPAC developments. The Book House is an interactive, multimedia, online public access catalogue system designed to support casual and/or novice end-users in information retrieval. It runs on a Macintosh and is available on CD-ROM and disks in English and Danish (it can be purchased from Risø for $100). It comprises an interface and module for classifying and indexing fact and fiction books in the database called Book House Write. It uses icons, text and animation in the display interface in order to enhance the utility of the system for the general public. Both words and pictures can be used for searching, which makes the system suitable for all age groups. It plays on users' previous experiencees with computer games to support learning by doing something in an enjoyable way. A prerequisite for the design of The Book House was a new approach to cognitive analysis of retrieval in libraries. Based on the success of this approach, it is claimed that OPAC systems will only be really useful and widespread (1) when their domain and task characteristics allow supplementary information to be added to existing descriptions of book content in online card catalogues in order to match end-users' intentions and needs, and (2) when the user interface and routes to the databases are configured as an integrated and uniform set of displays which match the search strategies of users, as well as their mental capabilities and limitations

Abstract

The Book House is an interactive, multimedia, online public access catalogue designed to support casual, novice users in information retrieval. It uses icons, text and animation in the display interface in order to enhance the utility of the system. A prerequisite for the design of The Book House was a cognitive analysis of users' information needs and search queries. The paper describes The BookHouse and discusses its relevance as a solution to the current OPAC developments

Abstract

Issues concerning the formulation and application of a model of how humans value information are examined. Formulation of a value function is based on research from modelling, value assessment, human information seeking behavior, and human decision making. The proposed function is incorporated into a computer-based fiction retrieval system and evaluated using data from nine searches. Evaluation is based on the ability of an individual's value function to discriminate among novels selected, rejected, and not considered. The results are discussed in terms of both formulation and utilization of a value function as well as the implications for extending the proposed formulation to other information seeking environments
