Today ResearchGate confirmed that people continue to read my 2019 presentation “Creating Intelligent Perpetually Running Applications with Business Rules” at the BBC conference. I reread its abstract: “In the AI era, many business applications which consider themselves “intelligent” cannot simply execute a complex rules-based transaction and wait for the next one. To become really “intelligent” applications, they should be able to learn from already executed transactions, accept new facts as they become available, and, when necessary, they should make changes in their own execution logic. This presentation describes a practical architecture that supports the creation and continuing development of such intelligent, perpetually running decision-making applications. This proposed architecture utilizes the modern pub/sub tools with continuous data streams and state machines, allowing subject matter experts to define and maintain behavioral and decisioning rules. It’s been demonstrated by using several real-world scenarios.” Then I went through my presentation with a new interest.
