Links - Rule Based Systems at the Vrije Universiteit Brussel (VUB)
Tons of interesting aritcles at the System and Software Engineering lab (SSEL) ... many need a bit of googling to find them all.
Many links can be found on the VUB Publications page. Also check out the thesises ... thesii ? ...
The general basis of many of the articles is Aspect Oriented Programming, but the focus at VUB is business rules and rule-based systems.

Obstacles to Rule Based Systems
What were the major obstacles that delayed the adoption of rule-based systems as a mainstream technology for the first 15 years of it existence ?
- Lack of consistent focus on the problem domain - particularly lack of business focus the application was an example of technology rather than catriona
- Lack a rigorous methodology -
Rule Based Systems for the Semantic Web
New Definitions for 'Semantic Web Rule Based Systems' ?
Many of the potential obstacles to adoption of the Semantic Web are similar if not identical to the prbblems faced by rule-based systems in the late 1980s. Therefore, the business rules methodology may be a good guide for development of the Semantic Web.
First, some basic principles.
Introduction to Rule Based Systems
A brief explanation about the unwieldy structure of this document ( as notes to myself if no one else ). The reader can skip this section by clicking on one of the links at the botton of the page.
This is the start of six sections devoted to the subject of rule-based systems. The sections started out as static HTML and are ( slowly ) being converted to the Drupal CMS, with extensive reorganization and revision. Frankly, this document has been difficult to write, for reasons described in "Defining Rule Based Systems".

Modeling the Subject of "Rule-Based Systems"
Definitions can be seen assertions about relationship between well-defined terms, in other words things are defined in terms of other things. The terms and relationships associated with "rule-based systems" are ill-defined and make a rigorous definition nearly impossible to achieve.
