- What talents are needed to create hypertext systems? <Sum10 1 4>
- ====================================================
-
- What is In building hypertext systems, I've come to the conclusion
- expertise? that there are at least three kinds of expertise:
- ========== fundamental, operative, and access. I define these
- categories of expertise as follows:
-
- ┌───────────────────────────────────────────────────────────────────────────┐
- │ Type of Expertise Essential Skill │
- │ ================= =============== │
- │ Fundamental Knowledge of the literature of a subject │
- │ Operative Knowledge of the shortcuts not described in books │
- │ Access Understanding why people want specific knowledge │
- └───────────────────────────────────────────────────────────────────────────┘
-
- Which is most Of the three types of expertise, understanding why people
- important? want to access knowledge is the most important thing to know
- ========= in building a hypertext system.
-
- Good hypertext systems match the needs of users by
- displaying desired information with a minimum number of
- keystrokes, regardless of the initial understanding of the
- subject area. For example, if you've answered technical
- questions for some time over the phone, you'll know the
- various abilities of the potential users of your system as
- well as the best way to explain the information.
-
- Automatic If you have this background, you can build good hypertext
- hypertext systems in your sleep. However, if you lack this
- ========= experience, here's the alternative approach.
-
- Our HYPERLINK package includes a decision tree building
- program <link27>. This program rapidly builds a network of
- hierarchies such that each hierarchy is directly suited to
- the needs of specific users to easily find whatever
- information they desire.
-
- Time to build Now the surprise! Having for several years sat in the PhD
- expert systems seminars and courses at UC Berkeley taught by Lofta Zeda
- ============== (pioneer of fuzzy logic), building an good 100-rule expert
- system <link64> typically takes 2 years and a lot of effort.
-
- The problem is that the builders of expert systems have
- confused access expertise with judgement expertise.
-
- Hypertext as an However, if I separate these two forms of expertise, I can
- expert system build a 500-800 rule access decision tree automatically in
- ============= a day using MaxThink and the PERM program of HyperLink.
-
- Hypertext simply provides rapid access to expert-level
- information to help users quickly make expert-level
- decisions. While not providing automatic browsing (AI),
- hypertext does provide sensitivity analysis on the
- validity of the information presented (something not found
- in AI).
-
- While a this is a complex issue, hypertext can replace most
- visions of expert systems. Call for details.
