- ABSTRACT
-
- Hypertext is an effective computer interface
- technology showing promise for information retrieval system
- applications. The ease of use and totally self-directed
- nature of navigating a hypertext information system using
- embedded associative links has drawn favorable reactions
- from system developers and implementors. However, many
- information retrieval specialists and librarians are
- concerned about the absence of planning for effective,
- consistent, controlled means of information organization
- and access. This exploratory study investigated the
- potential for transferring traditional, print-based methods
- of information retrieval to the hypertext medium.
- An extensive literature review provided background
- for construction of a conceptual model of traditional
- information access methods. The study used the established
- case study procedure of comparing a subject system against
- a proposed model, to establish the degree of agreement or
- disagreement with the hypothesis. The investigator
- selected an MS-DOS hypertext authoring system which
- apparently used some traditional information organization
- and structuring methods. Data collection methods included
- interview of the system developer and associates,
- examination of system documentation, informal interview of
- hypertext system developers using the system, and use of
- the subject system authoring tools for construction of a
- small hypertext system. Multiple means of data collection
- were used, allowing for cross-checking and verification of
- information. The data was interpreted by tabulation and
- examination of results against the traditional information
- access model.
- The study conclusively supported the hypothesis of
- the transferability of nearly all traditional information
- access and retrieval methods to the hypertext medium. It
- identified the hierarchical taxonomy matrix tool used in
- the subject authoring system as an accepted method of
- organizing information structure, and found it to be an
- effective hypertext authoring approach. It recommended the
- use of methods for insuring structured information
- organization, and tools to provide for consistency and
- control of access means. The study concluded that it would
- be productive for hypertext system authors to adopt a
- highly integrative approach, using a mixture of traditional
- information access methodologies to complement hypertext
- associative linking access and sophisticated information
- retrieval software approaches.
