January 2010 Entries

I am deeply engrossed at present in a new book, published at the beginning of this year, called 'Intelligent Systems - Principles, Paradigms and Pragmatics' by Robert Schalkoff, and published by Jones & Bartlett. Rather strangely, I note the copyright year is 2011, so I guess it fell through some kind of wormhole from the future. I don't think I have enjoyed reading an IT book as much in the last 20 years. The book is a modern introduction to the whole field of 'intelligent systems' (IS) which ......

So there I am doing what a geek does best - sitting in Cafe Nero on Tottenham Court Road in the centre of London on a Saturday afternoon, killing time while waiting to meet up with my daughter, and doing a little coding to pass the time when someone (his name turned out to be Jim) asks me "so what do you think of the Visual Studio 2010 beta?"

This is the third and final part of a three-part series, as follows: · Part 1: Situating the Business Rules Engine · Part 2: Backward Chaining: the 'Simple Name' pattern · Part 3: Backward Chaining: the ‘Bound Variable' pattern In Part 2 we looked at how developers can use procedural attachments and 'directive events' to implement a simple form of backward chaining for Microsoft's Business Rule Engine. In this third, and final, part, we will extend the code to tackle more complex backward-chaining ......

This is the second of a three-part series, as follows: Part 1: Situating the Business Rules Engine Part 2: Backward Chaining: the 'Simple Name' pattern Part 3: Backward Chaining: the ‘Bound Variable' pattern In part one of this three-part series, I explained some of the historical influences that led Microsoft to design their Business Rules Engine as a 'situated reasoning engine'. In this second part, I want to look at a pattern that exploits these features. Microsoft's engine is often described ......

This is the first of a three-part series, as follows: Part 1: Situating the Business Rules Engine Part 2: Backward Chaining: the 'Simple Name' pattern Part 3: Backward Chaining: the ‘Bound Variable' pattern Karl posted on forward and backward chaining at http://karlreinsch.com/2010... I emailed him privately and talked a bit about how backward chaining can be implemented on Microsoft's Business Rule Engine (I even sent him a little example). A couple of days later he published a ......
