- Short: Knowledge Based System Inference Net Builder

-
- ISTAR
-
- Istar is a knowledge based system builder that allows you to construct
- inference nets, bayesian nets and semantic nets. It has a particularly
- nice user interface, with a smoothness that only Amiga hardware can give.
- So it is useful for decision support, to help you clarify complex ideas.
-
- You build your knowledge base by drawing boxes and arrows, and then
- can run the KB direct. See Docs/.Intro to get going.

- NEW IN THIS VERSION (See Docs/History)
-
- This is a minor update from Version 1.05 (Jan 97), with better key control
- and minimize/maximize boxes. Version 1.05 added two major improvements -
- dynamic documents (albeit a limited facility just now) and the ability to
- add attributes to any existing item after it has been created.
-
- PLANS
-
- Next version I hope to put in a Lists facility that will allow
- relational algebra operations like union, intersection, and also
- make the goal list more flexible.
-
- ISTAR NEWS
-
- As bugs are discovered, as tips are suggested, and as better
- documentation is written, etc., - things that do not involve
- a new version of Istar - they will be put on Aminet as they arrive,
- under the name Istarnews. So Istarnews should appear in the RECENT
- list more frequently than versions of Istar.

- COPYRIGHT
-
- Istar, all versions, are copyright (C) Andrew Basden, University
- of Salford, Salford, M5 4WT, U.K. Andrew@basden.demon.co.uk.
-
- The version with this file can be used freely as long as all copies
- of it include the name 'Istar' in their file names whereever they
- are stored and as long as this file and copyright notice is
- kept with the file.
-
- SYSTEM REQUIREMENTS
-
- Known to work on Amiga 1200, 3000, 4000. Will just about run in
- 2Mb machines, but recommend use the IstarPrefs_LowMem as your
- preferences file.
-
- Assigns needed (can work without them):
- IstarSys: (has IstarPrefs and, in future, other things)
- KBTools: where KBs are saved etc.
- Fonts used (unless specified in IstarPrefs):
- Courier
- Garnet
- Topaz
- Libs used:
- iff.library (but can work without it)
-
- It works best if you assign KBTools: to the directory where you keep
- your knowledge bases, and IstarSys: to a directory where various system
- files are kept. At present, the only file sought in IstarSys is IstarPrefs.
- Otherwise just starts as Sys: root.
-
- FILES INCLUDED:
-
- Istar Main program.
-
- Other files are documentation. Read Intro first and it explains the
- other files.
-
- DISCLAIMER:
-
- Istar is supplied as-is.
-
- Istar is still under development. Some of its buttons do not work
- because they are not attached to anything yet. Some of its more
- exotic data transofrmations do not yet work.
-
- Let me know what you think of it, by mailing me at Istar@basden.demon.co.uk
