Here is a graphic on how various reasoning technologies fit the practical requirements for reasoning discussed below:
This proved surprisingly controversial during correspondence with colleagues from the Vulcan work on SILK and its evolution at http://www.coherentknowledge.com.
The requirements that motivated this were the following: Continue reading “Requirements for Logical Reasoning”
If you are using one of the more popular rules engines, chances are you can blame me. I popularized the technology of forward-chaining production rules based on the Rete Algorithm. Others have certainly contributed; my path is the one that led to open-source implementations and many commercial products, including those of IBM, Oracle, SAP, TIBCO, Red Hat, and too many others to mention (e.g., see this).
Today, I want to make clear that the future prospects for production rule technology are diminishing. My objective here is to explain why most rule-based technologies are no good and why some are much better. Although production rule technology is much better than most rule-based technologies, I hope to also make clear that in the age of IBM’s Watson, Google’s Brain, and the semantic web, production rule technology is inadequate.
They are not created equal.
Rules have become so pervasive in the software business that vendors of all types of software say they have them. Consider, for example, that even Microsoft Outlook has rules!
