Quickie release because v5.0 had the wrong version of Jatha integrated into it.
This release fixes a problem with backward chaining rules that appeared in the last release. Thanks to everyone who patiently waited for these fixes.
A new release of Algernon is available. This is compiled with Protege 2.1.2 (the final Protege v2 release). It is also compiled with Jatha 2.1, which adds additional functionality to the LISP backend. Also several bug fixes related to class loading that were interfering with running Google queries.
Version 4.8 is now available. It contains a few bug fixes and is recompiled with the latest libraries. Enjoy!
This is a recompile with Protege 2.1.1 (build 239) and Jatha 1.9. Versions of Jatha prior to 1.9 had an error in the floating-point divide routine. Jatha is a LISP library used internally in Algernon and is also accessible through the Algernon commands as an embedded LISP processor.
This version of Algernon fixes a stack overflow problem on large knowledge bases (> 10,000 frames). It also contains some other minor changes as detailed in the ChangeLog. Additionally it is compiled with Jatha 1.8 and Protege 2.1 (build 232).
This release fixes a bug in the handling of frames with a space in their names.
Algernon 4.2 contains a bug related to activating forward chaining rules, introduced in v4.2 That release is now
hidden and v4.3 is being released to correct the problem.
Algernon 4.2 is available. It fixes a minor but annoying bug in activating backward chaining rules when the slot name is a string rather than a symbol. Have fun!
This release of Algernon, a rule engine for Protege, is built using the Protege 2.0 final release. It also incorporates a few minor changes and the latest release of Jatha.
Since there are two versions of Algernon, v3 for Protege 1.9 and v4 for Protege 2.0, there are usually two releases at the same time. However, SourceForge only shows the last release by default. To view all of them, click on the "View all files released" link at the beginning of the paragraph of text above the list of released files.
Algernon v3.7.6 for Protege 1.9 and v4.0.2 for Protege 2.0 have been released. These versions enhance the trace output, fix the :ALL-PATHS command and add an example/ directory at the top level.
Versions of Algernon 4.0 and higher are compiled with Protege 2.0. Both Protege 2.0 and Algernon 4.0 should be considered beta code.
As of now, there are no differences between the Algernon 3.x and 4.x releases except they are compiled against different Protege jar files.
This release fixes a bug in the Protege backend accidentally inserted into release 3.7.2.
Release 3.7.4 replaces it.
Algernon 3.7.2 was released December 11, 2003.
It includes bug fixes as well as several new pseudo-KB backends and the Java2Protege program that converts Java class hierarchies into Protege ontologies.
