Artificial intelligence as writing: knowledge-based hypertext systems as a medium for communication

This thesis is an exploration of a new metaphor for artificial intelligence (AI). Traditionally, the computer within AI has been viewed as an agent, one with which the user engages in a conversation. More recently certain researchers have proposed the notion that artificial intelligence (and indeed computing in general) can be more appropriately seen as a form of writing. Initially this thesis reviews the literature in this area, and aspects of AI which support the approach. Features of writing are then described which show parallels with AI. This then allows us to take lessons from the history and development of both traditional writing and the new computer-based writing systems to inform the design of a new type of artificial intelligence system. A design based on these features, called Running Texts is presented through a number of small examples. Issues that arise from these and possible future developments, based on the implementation are then discussed. A rationale for users choosing to learn a system such as Running Texts is proposed, as benefits from the psychological and social implications of writing can be applied to AI systems, when they are seen as writing. The same parallels point out potential problems, and suggest new ways to see the relation between AI and thought

Developing a design methodology for the construction of hypertext and hypermedia, with particular reference to hypertext electronic prospectuses

Use and development of hypertext-based documents is becoming more widespread in both industry and die academic world. This has obvious implications for the design of hypertext documents. The hypertext designer has been relatively ignored until recently, with attention largely focused on the quality of the hypertext rather than support for the designer. Recent hypertext design methodologies, such as that described by Isakowitz et al. (1995) have made a useful contribution, but are oriented towards designers with a background in computing science and related professions. This research addresses this problem by the development of a design methodology which is intended to be accessible to the general author. The design methodology was based on three sources of data: a taxonomy of existing design guidance, including a range of principles and guidelines and previous design methodologies for hypertext; hypertext versions of a higher education college prospectus, and a case study of a CD-ROM higher education prospectus. This material was assembled and synthesised to produce a provisional design methodology that is positioned between existing design methodologies such as Relationship Management Methodology (Isakowitz et al 1995) and Object-Oriented Hypermedia Design Method (Schwabe et al 1995), which are influenced by software engineering and database design concepts, and other less formal descriptions of the hypertext design process. The design methodology supports and encourages iterative methods of working, and includes supporting documentation and pro formas designed to encourage a thorough approach to hypertext design
