- UNC CS Department, CS 290-059, Spring 1993
-
- HYPERTEXT MODELS AND SYSTEMS
-
- David Stotts
- stotts@cs.unc.edu, 962-1833, office 149 Sitterson
- contact me for more information
-
- meeting time: once a week, most likely Monday 3:00 -- 5:00.
- place: Sitterson Hall, room 325
- next meeting: Monday, 1/18
- We will discuss next Monday 2 papers by Vanevar Bush and one by Jeff
- Conklin (see reading list below) as background before getting into
- more recent research topics in subsequent classes.
-
-
- Hypertextual information systems were first envisioned by Vannevar Bush,
- science advisor to Roosevelt, and they have been researched since the
- mid-60's, but only in the last decade have computing resources become
- powerful and cheap enough for hypertext systems to proliferate and find
- broad application. In this seminar, we will be studying hypertext models,
- systems, and the information structures created and manipulated by such.
-
- Hypertext is a broad term for the integration of task with information.
- In this sense, a hypertextual structure is a value-added database or
- value-added information retrieval system. The simple abstract view of
- hypertext is a network (graph) of information nodes, but this network
- is meant to be "browsed" and interacted with in ways that traditonal
- databases and information systems are not. Visions for the eventual
- application of hypertextual structures extend from small single-author
- documentation to multi-author, multi-user "world wide webs" of data.
- Hypertextual forms range from straight-forward linked documents (very
- little integrated task expressed) to large-grained parallel algorithm
- (large amounts of integrated task expressed). Hypertextual structures
- have been used for program browsers and execution simulators, decision
- support systems, legal argument and mathematical proof presentations,
- software engineering support tools (design review, requirements,
- process models), and interfaces to databases, to name a few.
-
- A rough outline of topics follows:
-
- Models and formalisms
- Dexter
- HAM
- Garg's algebraic model
- Trellis
- Tompa's hypergraph model
-
- Systems
- KMS
- Notecards
- Intermedia
- Hypercard
- Hyperties
- Iris
- Trellis
-
- Implementation
- engines
- use of relational databases
- use of graph servers
-
- Issues
- Halasz' seven (ten) outstanding research issues
- query methods
- authoring/construction methods
- browsing methods
-
- Application areas
- hyperbases
- interactive data documents
- hypermedia
- collaborative processes
-
-
- We will study papers from the literature, meeting once a week for about
- 2 hours to discuss our readings and projects. In addition to reading
- and discussion, we will have several hands-on aspects to the course.
- There will be existing systems set up for students to use, and creation
- of hypertext documents in several systems will be required. We will also
- have one or two research systems available and students will work on an
- implementation project of their choosing using one of these research
- systems.

- =====================================================================
- Class Readings (part 1)
- =====================================================================
-
- I will be probably be adding (and perhaps subtracting) readings as
- we go along, based on how the seminar develops and what the class
- interests are, but these are the papers we will start with.
-
- I will make a copy of each available for you to Xerox from (in an
- envelope hanging on my office door) as I assign the reading, or you
- can find them yourself. We do not have a Xeroxing account for the
- class, so you are on your own for costs.
-
- Note that several of the papers are all from one issue of the
- CACM, July 1988.
