Short: Knowledge Based System Inference Net Builder Author: Andrew@basden.demon.co.uk Uploader: Andrew@basden.demon.co.uk Version: 1.06 Type: dev/misc 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. See the following Web pages: The main inca page is http://www.salford.ac.uk/iti/projects/inca/inca.html The main Istar page is http://www.salford.ac.uk/its274/istar/istar.html 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.
