- Short: Knowledge Based System Inference Net Builder
- Author: Andrew@basden.u-net.com
- Uploader: Andrew@basden.u-net.com
- Version: 1.14
- Type: dev/misc
-
- ISTAR KNOWLEDGE SERVER
-
- (Note: At present, in Aminet, Istar in dev/misc
- and KnowledgeServer in comm/tcp, are the same program.
- But in future they might diverge and have different
- capabilities or packagings.)
-
- 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 either direct or via a browser.
- See docs/index.html to get going. Most documentation is now in html.
-
- Istar has Knowledge Server capability. That is, knowledge bases
- created by Istar can be run over the Internet, worldwide.
- (Note: If you have a version of Istar1.1 that has a date on or before
- 6th October 1999, then you will find some tracing text that appears
- on the console when running in server mode. This was detected, and
- removed on 7th October 1999. The tracing merely shows stack usage,
- and is interesting: around 1k at that point - though best to keep
- stack high (20000) for other things.)
-
- See the following Web pages:
-
- The main Istar page is
- http://www.basden.u-net.com/pgm/Istar
- and information about the server is on
- http://www.basden.u-net.com/pgm/Istar/server.html
- which has a link allowing you to connect to the demonstration
- Istar Knowledge Server sites.
-
- NEW IN THIS VERSION (See docs/history.html)
-
- Version 1.14 makes a few small changes from version 1.12 (1.13 was never
- published).
- Version 1.12 fixes a couple of bugs, including one in the server that
- prevented long forms from being displayed. Main changes otherwise are
- that the client of server version can now start inference without a
- reset, and that the local lists panel is more powerful.
- Version 1.11 fixes a couple of bugs. Also makes it easier for the
- distant client to explore a KB. Otherwise it is version 1.1 in a
- different guise.
-
- But the major change is that Version 1.1 has been made into
- a knowledge server. That is, Istar can converse with a
- distant browser.
- In addition to a standard local user interface for the run-time user,
- there is also an interface to HTTP. Though the modular nature
- of Istar made it easy to get an initial version working, the
- inference engine required an overhaul before it could support
- multi-user access.
-
- Version 1.092 introduces reset values, which allows you to specify
- a default value to which an attribute will be set when a question is
- asked (previously it showed the value left there from previous
- working. See history.html). A few enforcer hits had been found
- and these have been fixed; see bugs.html. Help buttons are now
- available on forms.
-
- PLANS
-
- Next major version should be able to obtain info by downloading
- from any Internet site.
-
- COPYRIGHT
-
- Istar, all versions, are copyright (C) Andrew Basden, University
- of Salford, Salford, M5 4WT, U.K. Istar@basden.u-net.com.
-
- 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)
- Stack usage: 20,000 recommended, but real usage unknown.
- Surprisingly small, but once ran out when the standard 4k.
-
- 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.
- This Istar.readme and Intro files.
- Preferences files, especially IstarPrefs.server
- Server text files in files/ directory.
- Server KB text files and .serverkbs control file in KBs
- Documentation. Most is now html and cross-linked
- for easy reference. docs/Intro is an ascii version of index.html.
- Sample knowledge bases.
- Installation script.
-
- 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 transformations do not yet work. See bugs.html.
-
- Let me know what you think of it, by mailing me at Istar@basden.u-net.com
