“For many years, computer scientists have sought to create decision making tools based on the way humans reason.  Early expert systems in the 1980’s and 1990’s were quite limited, but they were central to the first wave of commercial success of Artificial Intelligence (AI).  Outgrowths of that technology,  business rules and decision trees, have become well established as distinct market sectors.  Now ubiquitous, they automate millions of mission critical business processes every day.  But automation of more complex human reasoning and knowledge remained illusive, due to technical limitations.” This paper claims game-changing advances that have come in the form of a knowledge representation and reasoning language called Rulelog. Attendees of RuleML+RR and DecisionCAMP  will be able to listen its presentation by Coherent Knowledge in London next month.
